A self-contained breathing apparatus (SCBA) supplies firefighters with their own compressed air source, letting them work safely in smoke, oxygen-deficient atmospheres, and other IDLH environments. Unlike an air-purifying respirator, an SCBA carries its own air rather than filtering ambient air, which is critical since fireground atmospheres often do not have enough oxygen to filter safely. A full system includes a facepiece, regulator, harness, cylinder, and PASS device, certified under NFPA 1970 (2025 edition), the standard that consolidated the former NFPA 1981. A.J. Stone carries the MSA G1 SCBA line and a full range of SCBA accessories.

The MSA G1 XR 2025 Edition SCBA is certified as compliant to NFPA 1970 (2025 edition), the consolidated standard that replaced NFPA 1981. It includes Bluetooth radio communications and a noise-cancelling integrated voice amplifier as standard, with no additional hardware required, plus a rechargeable battery system whose rapid charger handles up to six batteries at once. The facepiece platform comes in small, medium, and large to simplify fit across a department. See the full MSA G1 SCBA lineup or our MSA Knowledge page.

Under NFPA 1850 (2026 edition), which consolidated the former NFPA 1852, an SCBA assigned to an individual should be inspected at the beginning of each duty period, and units carried on apparatus but not individually assigned should be inspected at least weekly, with no more than one week between inspections. Flow testing on a calibrated test bench is required at least annually, and additionally before a unit enters service, after any repair or rebuild, and after a severe exposure. Inspections should cover cylinders, facepieces, regulators, PASS devices, and harness components, since a failure in any one can put a firefighter at risk on scene. NFPA 1850 also introduced SCBA retirement language: units retire at 15 years from date of manufacture, extendable to 20 years where the owner installs manufacturer upgrade kits that keep the unit within two editions of the current standard. A.J. Stone provides SCBA inspections, maintenance, and flow testing for departments across Ontario through our in-house and mobile service program.

Yes. A.J. Stone provides both mobile and in-house SCBA servicing across Ontario, including inspections, flow testing, preventative maintenance, repairs, and compliance testing. Keeping this with a supplier who also sells the equipment means one point of contact for both purchasing and upkeep.

Common SCBA accessories include facepieces, RIT bags and accessories, fill stations, chargers, replacement cylinders, regulators, and integrated communication systems. This modularity lets departments upgrade individual components as standards evolve rather than replacing the whole unit.

A Rapid Intervention Team (RIT) bag provides an emergency, portable air supply that a RIT crew can connect to a downed firefighter's SCBA regulator, buying critical time during a mayday event. RIT bags are typically staged pre-connected and ready to deploy. See A.J. Stone's RIT Systems and RIT Accessories collections.

A.J. Stone carries Innotex as our bunker gear brand, spanning the Classic and Energy lines for different levels of mobility and thermal protection. For departments wanting a more tailored fit or look, we also offer A.J. Stone Elite Spec Custom Bunker Gear, built on the Innotex platform with configurable options. Round out a full turnout with Boots from our broader PPE lineup.

Turnout gear must be retired no more than 10 years from its date of manufacture. This is a mandatory retirement requirement, not an inspection trigger, and it applies regardless of how lightly the gear has been used or how well it has been cared for. Two details departments frequently miss: the clock runs from the manufacture date rather than the date the gear entered service, and each ensemble element carries its own date, so a coat, pant, helmet, hood, gloves, and boots can all age out at different times. Gear must also be retired earlier than 10 years if it is contaminated beyond cleaning, damaged beyond repair, or fails an advanced inspection. The requirement originated in NFPA 1851 and now sits in Chapter 10 of NFPA 1850 (2026 edition). Talk to us about planning a bunker gear replacement cycle before gear ages out mid-budget-year.

Essential structural PPE includes bunker gear, a helmet, gloves, a hood, boots, SCBA, and eye protection. NFPA 1970 (2025 edition), which consolidated the former NFPA 1971, governs how these pieces are certified to work together as a full ensemble. Missing or mismatched components, such as a hood that does not interface correctly with the SCBA facepiece, can create gaps that are not obvious until they matter.

Modern bunker gear has improved on thermal protection, mobility, moisture management, and safety through anatomically contoured cuts and moisture barrier technology not made with PFAS. Some lines also add particulate-blocking hoods designed to reduce carcinogen exposure, a growing focus industry-wide.

Gear exposed to smoke, soot, or hazardous materials should get preliminary exposure reduction on scene, immediately after exiting, followed by advanced cleaning before it returns to service. NFPA 1850 (2026 edition) requires advanced cleaning a minimum of twice in any 12-month period, with at least one of those paired with an advanced inspection. Using the wrong detergent or washer can degrade protective barriers faster than normal wear, so gear should only be cleaned with products rated for turnout. A.J. Stone supplies decon detergent and washers and extractors built for PPE specifically.

Yes. A.J. Stone provides PPE inspection, repair, and maintenance services to help departments stay compliant with NFPA 1850 and keep gear performing between replacements. Regular inspection catches issues like seam separation before they become a safety concern. Contact us through our in-house and mobile service page to schedule.

A.J. Stone offers structural firefighting helmets, rescue helmets, face shields, visors, and helmet accessories, in both traditional and modern styles depending on department preference. We also offer custom helmet configuration, including passport-style and standard fronts.

A CAFS injects compressed air into a foam-and-water solution before it reaches the nozzle, producing foam with higher velocity and lower expansion than water alone. That knocks down fire faster while using less water, reducing both suppression time and water damage. Enforcer's units scale from the 10-gallon Enforcer 10 up to the 200-gallon Enforcer 200. See A.J. Stone's Enforcer CAFS collection and CAFS System collection.

CAFS systems improve water efficiency, increase suppression effectiveness, reduce firefighter fatigue from hose handling, and improve exposure protection, since the foam clings to vertical and overhead surfaces better than plain water. Departments running CAFS often use a fraction of the water volume for comparable knockdown.

A.J. Stone offers a selection of fire suppression foam including Class A foam, Class B and A/B fluorine-free foam, foam eductors, and application equipment, including Enforcer's FIREBULL line. FIREBULL's F3 fluorine-free foam is positioned as a transition product for departments moving away from AFFF, and a Climate Control Premix is rated to -40°C for Canadian winters.

Class A foam is a wetting agent for ordinary combustibles like wood and paper, helping water penetrate rather than run off. Class B foam is formulated for flammable liquid fires and works by forming a vapour-suppressing blanket over the fuel surface. Some concentrates, like FIREBULL's A/B line, handle both from one product. See A.J. Stone's Fire Suppression Foam collection to compare.

Foam system equipment typically includes eductors, foam-capable nozzles, monitors, proportioners, flow meters, and CAFS units. An eductor draws concentrate into the water stream at a set percentage without a dedicated pump-mounted system, making it a simple entry point for foam operations. A.J. Stone carries Task Force Tips nozzles and eductors alongside Enforcer's lines. Browse Nozzles & Valves and Fire Suppression.

Yes. A.J. Stone works with departments to recommend foam systems based on apparatus configuration, call type mix, and operational requirements rather than a one-size-fits-all default. Proportioning method matters here — some fluorine-free concentrates are specified for external in-line eductors and are not approved for around-the-pump proportioners, so the foam and the delivery system need to be specified together. Browse Enforcer and Fire Suppression Foam to start comparing and request a quote to one of our sales reps who will reach out to you with a custom order.

Fire hose nozzles are selected based on flow rate, application, pressure needs, and department preference built up over years of experience. A nozzle needs to match the pump capacity and hose diameter it is paired with, or performance suffers regardless of its rating. See A.J. Stone's Task Force Tips collection and Nozzles & Valves to compare

Task Force Tips (TFT) nozzles are used for fire suppression, exposure protection, foam application, and specialty operations like piercing or high-rise work, and the brand is known industry-wide for durability and consistent flow. TFT also builds Bluetooth-enabled flow meters that let crews confirm actual flow versus rated flow in real time.

A piercing nozzle injects water or foam directly into concealed spaces — behind walls, into vehicle compartments, or through aircraft skin — without needing full physical access to the fire. This is valuable for fires in spaces that are unsafe or too slow to open up conventionally.

Smooth bore nozzles provide a solid stream for maximum reach and penetration, useful for knocking down fire from a distance. Fog nozzles produce an adjustable spray pattern, better suited to cooling and exposure protection. Many departments carry both, since call types vary enough to justify having each on hand. See A.J. Stone's Task Force Tips collection to compare.

A.J. Stone carries fire hose, intake and discharge valves, hose bridges, suction hose, hose testing equipment, and strainers, including Kuriyama fire hose. Hose selection is not just about diameter — burst pressure rating, coupling type, and weight all factor into what fits a given apparatus. We also offer custom hose configurations and hose testing equipment.

High-rise operations often require hi-rise kits, lightweight hose packs, pressure-reducing equipment, and specialized nozzles built to be carried up multiple flights when elevators are not usable. Pressure-reducing valves matter especially here, since standpipe pressure can vary significantly floor to floor. A.J. Stone carries hi-rise equipment alongside our Hose and Adapters collections. Contact us for a recommendation suited to your building stock.

Rescue air bags are used for lifting, stabilization, extrication, and collapse rescue, giving crews a controlled way to create space or shift weight without sudden movement. Paratech's MaxiForce G3 line comes in 14 sizes, with the largest rated to lift, move, or shift up to 106 U.S. tons. Paratech also states that it produces the only air lifting bag ATEX certified for use in explosive environments, which matters for pipeline, mining, and industrial rescue applications. See A.J. Stone's Paratech Rescue Equipment collection and Lifting Bags.

High pressure air bags provide precise lifting in tight spaces, like under a vehicle chassis, where a smaller footprint matters more than surface area. Low pressure bags lift large loads over greater surface areas, better suited to structural collapse where weight is not concentrated on one point.

A.J. Stone offers rescue equipment from Paratech and Power Hawk Technologies, along with Genesis Rescue Systems battery-powered extrication tools. Carrying multiple brands lets departments mix stabilization, lifting, and cutting equipment to fit each tool category best.

Genesis EForce rescue tools are battery-powered extrication tools for cutting, spreading, and vehicle rescue. Each tool contains an electric motor driving an onboard hydraulic pump, which eliminates the separate power unit and hose run that traditional rescue tools require. The current SLi generation runs on the standard Milwaukee M18 battery platform rather than a proprietary pack, so departments already invested in that platform can share batteries across tools. That cordless design matters most at scenes with limited access. See our Genesis EForce cutter specifications for model-by-model detail.

Vehicle stabilization systems secure a vehicle during extrication, preventing shifting or rolling that could injure the patient or crew mid-operation. Paratech's Vehicle Stabilization Kits scale across several configurations: the Highway VSK uses four struts and is rated to 80,000 lbs with an 8-foot reach, while the Interstate VSK is rated to a maximum load of 120,000 lbs with a 4:1 safety factor and reaches up to 14 feet using LongShore struts.

Rescue air cushions provide controlled, gradual lifting during technical rescue, typically used under a vehicle or load where a rigid strut is not practical. Because they inflate progressively, crews can fine-tune lift height in small increments.

A.J. Stone supplies portable gas detectors, calibration gas cylinders, monitoring accessories, and air filtration systems, including MSA's multigas detector lineup. Portable detectors are typically configured for four-gas monitoring — oxygen, combustible gas, carbon monoxide, and hydrogen sulfide — as a baseline.

Gas detection equipment helps firefighters identify hazardous atmospheres, oxygen deficiencies, and toxic or combustible gases before they become an exposure risk. It is critical in confined space, hazmat, and industrial calls where hazards are not visible. Continuous monitoring through an incident, rather than just an initial reading, catches conditions that shift as ventilation or fire behaviour changes.

Gas detectors should be bump tested before each use to confirm sensors respond correctly, and calibrated on a schedule set by the manufacturer, typically monthly to annually depending on sensor type and usage. A device that passes a bump test but is overdue for full calibration can still drift out of accurate range.

Gas detection is common in firefighting, industrial safety, confined space entry, hazmat response, and general emergency services — anywhere workers enter an atmosphere that is not pre-confirmed safe. Fire departments increasingly carry it beyond hazmat calls, for routine structure fires and CO complaints too.

Thermal imaging cameras (TICs) help firefighters locate victims, identify hotspots behind walls or ceilings, and improve visibility and situational awareness in smoke. A TIC reads heat signatures rather than visible light, so it works in zero-visibility smoke where a flashlight is nearly useless. A.J. Stone runs a Seek Thermal trade-in program for departments upgrading their units.

A.J. Stone offers flashlights, floodlights, portable scene lighting, helmet-mounted lights, hand-held lights, and rechargeable emergency lighting, including Streamlight products. Scene lighting has shifted toward battery-powered, rechargeable systems, reducing dependence on generator power and cords at a scene.

Proper scene lighting improves safety, visibility, and scene management, particularly at night or during structure fires where smoke and darkness compound each other. Poor lighting slows down hose lays, patient care, and accountability tracking, and raises trip-and-fall risk. A.J. Stone's Firefighting Lighting Equipment collection covers scene, hand-held, and helmet-mounted options.

A.J. Stone supplies a wide ventilation collection that includes electric fans, gas-powered fans, battery-powered fans, smoke ejectors, and ventilation accessories, covering both positive pressure ventilation (PPV) and traditional smoke ejection. Fan choice usually comes down to balancing portability, noise, and airflow against apparatus space and battery logistics.

PPV pushes fresh air in through one opening and forces contaminated air out through another, improving working conditions and search visibility. Used correctly, it can significantly cut the time needed to clear smoke compared to natural ventilation alone. Timing matters, because PPV started before a fire is located can sometimes intensify it. See A.J. Stone's Ventilation collection for PPV-rated fans.

Electric fans are quieter with no exhaust emissions, useful for confined-space ventilation. Gas-powered fans offer greater portability without a cord run and often move more air, suiting large-area or exterior setups. Battery-powered fans split the difference — quiet, but cordless.

Proper decontamination reduces exposure to carcinogens, soot, and hazardous materials that accumulate on gear during operations, and is a major focus in the fire service given documented elevated cancer rates among firefighters. Preliminary exposure reduction on scene, followed by thorough station cleaning, reduces the window of exposure before contaminants transfer to apparatus or living quarters. A.J. Stone's Decon collection and Decontamination Systems cover both.

A.J. Stone carries decon showers, SCBA washers, cleaning detergents, gear dryers, and cleaning products for everything from on-scene exposure reduction to full PPE laundering. Using detergents and washers rated for turnout gear matters, since standard laundry products can degrade moisture barriers and compromise NFPA 1850 compliance. See Decontamination Systems, Detergent, and Washers & Extractors.

An SCBA washer cleans breathing apparatus components — facepieces, regulators, and harnesses — removing soot and biological residue while improving hygiene and equipment longevity. Manual cleaning alone often misses residue trapped in valve seats and straps.

Firefighting gear should be cleaned after any exposure to smoke, hazardous contaminants, or bodily fluids, rather than on a fixed calendar schedule, since contamination depends on what a call involves. Separately from exposure, NFPA 1850 requires advanced cleaning a minimum of twice in any 12-month period regardless of how many exposures occurred, with at least one of those paired with an advanced inspection. A.J. Stone supplies the detergent and washers and extractors for routine in-house cleaning, and can advise on advanced cleaning compliance.

The MSA G1 XR 2025 Edition SCBA has received NIOSH approval and SEI certification as compliant to NFPA 1970 (2025 edition), the consolidated standard that absorbed the former NFPA 1981. Meeting the current edition matters for departments doing new apparatus purchases or grant applications, since procurement specs often reference the standard by name and edition. A.J. Stone can walk you through which G1 configurations meet your department's certification requirements. See the full lineup on our MSA G1 SCBA product page.

The G1 platform includes integrated Bluetooth radio communications and a noise-cancelling integrated voice amplifier, both standard with no additional hardware required. That is a real advantage on the fireground, where garbled radio traffic can slow down a response. Browse our full MSA G1 SCBA collection to see facepiece and control module options that support this.

The G1 rechargeable battery system replaces disposable batteries. The portable rapid charger can charge up to six batteries at once, with batteries reaching a full charge in about six hours. For departments running multiple shifts, that turnaround makes it realistic to keep spare batteries cycling without falling behind. A.J. Stone carries both the rechargeable battery pack and the charging station.

MSA specifies the G1 facepiece at an 86% effective field of view with a 122% overlapping field of view, and offers it in three sizes — small, medium, and large — with colour-coded harness points to make sizing obvious on the rack. It is also built without electronic components on the facepiece itself, cutting weight and removing a potential snag or entanglement point. Check the MSA G1 SCBA Facepiece on our site for pricing and availability, and talk to us about arranging fit testing across your department.

Yes. A.J. Stone can set up a demo so your crews can try the G1 SCBA's facepiece, controls, and communication features firsthand before committing to a purchase or fleet upgrade. Hands-on time matters here, since fit and control-module familiarity affect adoption more than a spec sheet ever will. You can schedule a G1 SCBA demo directly through our site, and our team will follow up to arrange timing.

CrewProtect™ 100 is a self-contained air decontamination unit that mounts in apparatus cabs to reduce three things firefighters are exposed to daily: VOCs, particulates, and airborne aerosols. TFT rates it to capture over 99.5% of particulates and over 95% of VOCs. It moves 100 CFM, which clears a 350 cubic foot cab in roughly three and a half minutes, or a 500 cubic foot cab in about five. An LED indicator tracks cartridge condition — blue for good, amber around the five-month mark, red when replacement is required — so crews know exactly when it is time. See the TFT CrewProtect™ 100 on our site for specs and pricing.

A Bluetooth flow meter installs in line between two hose sections and reads water flow in real time on a paired smart device, with no wires or batteries to manage. TFT's SHO-FLOW® 1 is self-powered by an internal water-driven turbine that passes debris up to one inch, and connects to nozzles, hoses, and portable or fixed monitors using the appropriately sized coupling. That makes it useful for pump testing, live-fire training, and confirming actual flow versus rated flow on scene. Check the TFT SHO-FLOW® 1 Bluetooth Flow Meter for full specs, including the minimum flow needed to power the unit.

An in-line foam eductor draws concentrate into the water stream at a set percentage, so crews can apply Class A, Class B, or AR-AFFF foam without a separate pump-mounted system. TFT's eductor series uses an adjustable metering knob for different foam percentages and includes a back-flush button for quick cleanout on scene. They are built in hardcoat anodized aluminum, which matters for equipment that sits wet on an apparatus for years. Browse the TFT Eductor Series to compare flow ratings and coupling options.

TFT's adapter and valve lineup covers hose adapters, intake valves, gated wyes, hydrant valves, and ball intake valves designed to keep water supply operations compatible across different apparatus and hose configurations. That matters most at mutual aid calls or hydrant hookups where coupling standards do not always match between departments. TFT's catalogue spans NPSH, Storz, and CODE-AT configurations, though available threads vary by valve family — browse the TFT collection or ask us to confirm the right fit for your apparatus.

Yes. A.J. Stone works directly with Task Force Tips to help departments see equipment in action before purchasing, whether that is a nozzle, monitor, or foam system. Hands-on trials matter here, since flow characteristics and control feel are hard to judge from a spec sheet alone. Contact us and we will help arrange a demo or answer questions on any product not listed on the site.

Paratech's strut systems are built for trench rescue, structural collapse, and vehicle stabilization work, where crews need equipment that holds under unpredictable load. The strut heads and bases are milled from solid aircraft-grade aluminum rather than cast, then hard-coat anodized for strength and resistance to the elements. A.J. Stone carries the full Paratech strut and strut kit lineup — see our Paratech Rescue Equipment collection for available systems.

The kits scale up by reach and load capacity. The Standard VSK is the entry configuration for routine passenger vehicle stabilization. The Highway VSK uses four AcmeThread struts with up to 3 feet of extension each, letting crews create two A-frame stabilization triangles and reach up to 8 feet, rated to a maximum load of 80,000 lbs with a 4:1 safety factor. The Interstate VSK steps up further, rated to 120,000 lbs with the same 4:1 safety factor and capable of reaching up to 14 feet using LongShore struts, which suits loaded commercial vehicles and multi-vehicle collision scenes. Compare kits on our Paratech collection page to find the right fit for your response area.

The HydraFusion Strut combines shoring and hydraulic lifting in one tool, rated to lift up to 10 U.S. tons with a 2:1 safety factor and shore up to 20,000 lbs with a 4:1 safety factor. A built-in dual shaft end adapter lets it work with Paratech's LongShore, LockStroke, or AcmeThread struts and extensions, so departments can extend an existing strut inventory rather than replace it. That combination of lift and stabilization in a single tool is useful on heavy vehicle extrication calls where you would otherwise need separate lifting and shoring setups.

Air lifting bags handle everything from gently shifting debris in urban search and rescue to lifting heavy vehicles and industrial loads. The MaxiForce G3 line comes in 14 sizes, with the largest model rated to lift, move, or shift up to 106 U.S. tons. Paratech also states that it produces the only air lifting bag ATEX certified for use in explosive environments, which matters for pipeline, mining, and industrial rescue applications. Browse Paratech Air Lifting Bags on our site to compare capacity and insertion height across models.

Paratech's Dual Deadman Strut Controller G3 and Strut Regulator are built with integrated safety relief valves to protect against over-pressurizing during a lift or shore. All couplings and fittings are made of corrosion-resistant, non-sparking brass, which matters when equipment is used around fuel, gas leaks, or other hazardous environments. A.J. Stone carries the Dual Deadman Strut Controller G3 along with the Paratech Adjustable Strut Regulator and Shutoff and Inline Relief Valve to round out a strut system.

A.J. Stone's Paratech Knowledge Centre covers the full product family in one place: vehicle stabilization kits, air lifting bags, structural and trench shoring systems, pneumatic control equipment, and forcible entry tools. It is built for departments comparing models before a purchase decision, since spec sheets alone do not always make the tradeoffs clear. Visit the Paratech Knowledge Centre for model-by-model detail.

PFAS are a class of chemicals used in many everyday products, and historically in water- and oil-repellent coatings, including some turnout gear moisture barriers. Innotex now offers gear that is not made with PFAS, built around non-fluorinated barriers such as the Alpex FR3 moisture barrier. This reduces one route of chemical exposure for firefighters without giving up water and contaminant protection. See the Innotex Gray™ Particulate Blocking Nano Hood and the PREVENT CLEAR 25 Hood, both built without PFAS.

Classic is Innotex's standard turnout platform, while Energy adds anatomically responsive features that give firefighters improved freedom of movement and comfort without adding bulk or compromising thermal protection. In practice, that means a more contoured fit designed to move with the body during active firefighting rather than against it. A.J. Stone carries both lines: the Innotex Classic™ RDG10 and RDG20, plus Energy™ RDG40, RDG50, and RDG60. The RDG designation marks Innotex's Rapid Delivery Gear program, which ships stock configurations in 15 working days or less — worth knowing if you need gear before a custom order could arrive.

The AIRFLOW™ 3D Padding System is a three-dimensional padding system that cushions the SCBA against the body while creating airflow channels, making the pack more comfortable to wear over long deployments. It is typically paired with the INNOTEX ENDURANCE™ Integrated Knee Guard System, designed to move with the firefighter's natural stance rather than restrict it. These features come standard on Innotex's higher-end lines, including the Innotex Energy Customizable Bunker Gear A.J. Stone offers.

Standard knitted hoods can let microscopic carcinogenic particles travel through the fabric during smoke exposure. Innotex Gray hoods use a particulate-blocking interface built with DuPont™ Nomex® Nano Flex, which blocks more than 99.9% of particles between 0.1 and 1.0 microns, and the hood and its components are not made with PFAS. A second option, the PREVENT CLEAR 25 hood, uses a Stedair® Prevent Clear nanofiber barrier blocking 98% of toxic particles, also without PFAS. Both are meaningful upgrades for departments focused on reducing carcinogen exposure during and after fireground operations. See the Innotex Particulate Blocking Gray™ 25 Hood on our site.

Innotex advises against storing turnout gear in quarters where firefighters live, eat, or sleep, or in vehicle storage compartments, which helps limit UV degradation and reduces contamination exposure for the firefighter and others nearby. Gear should be hung neatly and protected from sharp objects, UV rays, sunlight, and extreme temperatures. When gear does need to be carried in an enclosed space, keeping it in a sealed gear bag helps contain residue. Good storage habits extend gear life well beyond what cleaning alone can do.

A CAFS injects compressed air into the foam solution before it reaches the nozzle, producing foam with high velocity and low expansion that knocks down fire faster while using less water overall. That matters both for extinguishing speed and for reducing water damage to structures and contents during suppression. A.J. Stone carries the full Enforcer CAFS lineup — see the Enforcer collection to compare unit sizes.

The numbers refer to pressure vessel capacity in U.S. gallons, which scales up the finished foam output. The Enforcer 10 holds 10 gallons and produces up to 200 gallons of finished foam, UL 711 rated 20:B. The Enforcer 30 produces up to 600 gallons and is UL 711 rated 10:A and 60:B. The Enforcer 60 produces up to 1,200 gallons, and the Enforcer 200 produces up to 4,000 gallons of finished foam for larger apparatus or industrial applications. Compare the Enforcer 10, Enforcer 30, Enforcer 60, and Enforcer 200 to find the right fit for your apparatus.

Fluorine-free foams like FIREBULL are formulated without the fluorinated compounds found in traditional AFFF, which have drawn increasing environmental and health scrutiny across the fire service. Enforcer positions the FIREBULL F3 line as a seamless transition product for departments moving off AFFF. One important specification detail: the FIREBULL Fluorine Free 3% UL product is recommended for external in-line eductors only and is not approved for around-the-pump proportioners, so departments should confirm their proportioning method before switching. A.J. Stone can help you check that. We carry FIREBULL A/B Concentrate Fluorine Free Foam and FIREBULL F3 Fluorine Free Foam.

Yes. The FIREBULL F3 Climate Control Premix -40°C uses a proprietary additive, not antifreeze, to withstand temperatures down to -40°C, so departments in colder regions of Canada are not stuck choosing between foam performance and freeze protection. Note that this product is a premix rather than a concentrate, so it requires no dilution. A separate FIREBULL A/B Climate Control concentrate rated to -40°C is also available if you would rather stay on a concentrate. Either is a practical consideration for any apparatus that sits outside or responds in winter conditions for extended periods. See the FIREBULL F3 Climate Control Premix on our site.

Class A foam is a wetting agent designed for structural and wildland fires involving ordinary combustibles like wood and paper, helping water penetrate material more effectively. FIREBULL A/B Concentrate is built to handle both Class A materials and Class B flammable liquids, giving departments broader coverage from a single concentrate if their call volume includes vehicle or flammable-liquid fires. It is also compatible with Class A and B tanks, pumps, and standard firefighting equipment. A.J. Stone stocks both the FIREBULL Class A Wetting Agent Foam and FIREBULL A/B Concentrate, plus Training Foam for live-fire drills where you do not want to burn through operational stock.

BullsEye™ uses LED flames paired with a laser-driven extinguisher, and its sensors detect whether the trainee has properly aimed the extinguisher and is correctly sweeping the nozzle. Instructors can adjust the fire class and difficulty level so flames grow or shrink in response to trainee technique, and because there is no real fire or chemical agent involved, there is nothing to clean up afterward. A.J. Stone carries the BullsEye Digital Fire Extinguisher Training System for departments looking to add repeatable, low-maintenance extinguisher training.

Yes. LION's BullsEye is portable, safe, and effective, and can be reset quickly for multiple participants both indoors and outdoors, which makes it well suited to school visits, safety fairs, and public events beyond routine firefighter training. It is also commonly used to train current and future firefighters, so departments get double use out of one system.

BullsEye ships with a 5-pound laser extinguisher standard, with optional 10-pound or 20-pound extinguishers available to better match the weight and handling of real equipment. For departments that want tactile feedback closer to a live extinguisher, BullsEye can also pair with a pressurized air-and-water SmartExtinguisher. A.J. Stone stocks the SmartExtinguisher for the Digital Fire Extinguisher Training System as an add-on.

The manikin uses embedded heat emitters combined with heat diffusion technology to simulate a person's thermal signature, running 20 to 30°F over ambient room temperature so it reads realistically through a thermal imaging camera. A built-in thermostat maintains that temperature, and the manikin is anatomically correct with uniform weight distribution and movable joints, plus a sound-activated or timed voice box for added realism. See the LION SmartDummy Thermal Manikin on our site.

Departments have historically used real people to act as victims during thermal imaging camera drills, but that exposes them to unsafe conditions like smoke-filled structures or simulated building collapse scenarios. A manikin removes that risk while still letting trainees practice locating a heat signature in low-visibility conditions, and built-in power supplies make it usable for outdoor, cold-weather, and wilderness search training as well. A.J. Stone also carries the SmartDummy Rescue and SmartDummy Extrication manikins to round out a training program.

A.J. Stone provides both in-house and mobile repairs for MSA, Task Force Tips, Irwin Air Ltd, LION, Streamlight, and Aerotecnica Coltri, so departments are not limited to shipping equipment out for every repair. Our factory-trained technicians are certified on the specific brands we service, which matters since incorrect repairs can void a manufacturer warranty.

Buying and servicing equipment from one supplier means a single point of contact for warranty claims, parts, and repair scheduling, rather than juggling separate vendors. A.J. Stone's approach is "we service what we sell," so support does not end at checkout. See our In-House & Mobile Service page for the brands we currently service.

A.J. Stone services MSA, Task Force Tips, LION, Streamlight, Irwin Air Ltd (breathing air compressors), and Aerotecnica Coltri (high-pressure breathing air compressors), covering SCBA, compressors, nozzles, training equipment, and lighting. Having multiple brands under one service program means departments running mixed equipment fleets can consolidate their maintenance schedule. Browse the In-House & Mobile Service page for details.

In-house service means bringing equipment to A.J. Stone's facility for repair, while mobile service means our technicians come to your station, which is useful for larger equipment or when a department cannot be without a unit for the travel time. Which option makes sense typically depends on the equipment type and how urgent the repair is.

Departments can reach out directly through A.J. Stone's In-House & Mobile Service page or by contacting our team to arrange a repair, whether it is a quick fix or a full inspection. Our technicians will walk through the issue and recommend whether in-house or mobile service is the right fit.

The Sensor Warranty Replacement program lets departments claim a replacement MSA ALTAIR XCell® sensor under warranty rather than paying full price for a suspected defective unit. After submitting the required serial number and date code, a representative from A.J. Stone's service department follows up on the request.

The date code and serial number are printed on the back of the detector. The sensor's own serial number is located inside the unit. If you are not comfortable accessing it, contact our service team and we will walk you through it or handle the lookup for you. Recording both numbers accurately before submitting a claim helps avoid delays in processing. Full photo instructions are available on our Sensor Warranty Replacement page.

Before sending in an LEL/Pentane sensor, fully charge the detector, leave it powered off for 24 hours, and recalibrate, since this resolves many apparent sensor faults without needing a replacement. If the issue persists after recalibration, the sensor can then be submitted for a warranty claim. See our Sensor Warranty Replacement page for the full troubleshooting steps.

A flashing End-of-Life indicator sometimes just means the detector needs a fresh calibration rather than a sensor replacement, so try another bump test or a full calibration first. If the indicator keeps flashing after that, the sensor is likely due for a warranty replacement. Submit your claim through our Sensor Warranty Replacement page.

Once you fill out the form with your date code, serial number, and a description of the issue, A.J. Stone's service department reviews the claim and reaches out with next steps. This keeps the process straightforward, since it is handled by the same team you would contact for any other MSA service question.

This program lets departments submit information on their Paratech air lifting bags and find out whether they are still good, approaching the end of their service life, or already past it. A.J. Stone provides guidance for each outcome, including how to extend the life of bags still in good condition. Start a check through our Check Your Air Bags Service Request page.

Air lifting bags, like most rubber and rescue equipment, have a manufacturer-rated service life, and using a bag past that point can mean reduced lift capacity or a higher risk of failure under load. A.J. Stone's trade-in program checks your bag's status and lets you know whether it is still good to use.

Proper storage, avoiding unnecessary UV exposure, and following manufacturer inflation limits all help extend a rescue air bag's service life. A.J. Stone's Air Bags Service program includes care tips specific to your bag's current condition rather than generic advice.

It is worth planning a replacement order ahead of time rather than waiting and leaving your department without a working set. Paratech's current MaxiForce G3 line spans 14 sizes, so there is usually a direct equivalent to whatever you are retiring, and A.J. Stone can help identify the right replacement lifting bag models and timing once your bags are checked. See our Check Your Air Bags Service Request page to check your current inventory.

The Check Your Air Bags program is built around Paratech's air lifting bag line, since A.J. Stone is a Paratech dealer with direct access to product and service information. If you have a different brand, contact our team directly and we can advise on next steps.

Departments can trade in any thermal imaging camera, regardless of brand or condition, and receive a credit towards a new Seek Thermal TIC. This makes upgrading to a current-generation TIC more affordable, especially for departments retiring an older or damaged unit.

No to both. The Seek Thermal Trade-In Program accepts any thermal imaging camera, any brand, in any condition, so a damaged, outdated, or non-functional unit from any manufacturer still qualifies. The goal is to help departments upgrade regardless of what they are currently running.

The two lines differ in price point and feature set, which is reflected in the trade-in credit each qualifies for. The AttackPRO Series spans several models, including the AttackPRO, AttackPRO S, AttackPRO VRS, and AttackPRO+ NFPA, while the FirePRO Series includes the FirePRO 200 and FirePRO 300. A.J. Stone can help match the right model to your department's call volume and budget. Browse our Thermal Imaging collection or start a trade-in on our Seek Thermal Trade-In page.

Founded in 1972 by the late Alfred Joseph (A.J.) Stone after years in the fire industry's manufacturing and sales side, A.J. Stone Company Ltd. has grown into a well-known name across Ontario and Canada's fire and emergency services market over more than 50 years. The company is run today by second and third generation fire specialists with hands-on fire service backgrounds. That kind of continuity is uncommon in equipment supply, and it shapes how the company builds relationships with departments and product partners alike.

A.J. Stone's head office and 20,000-square-foot warehouse sit at 62 Bradwick Drive in Vaughan, Ontario, minutes from major GTA highways, keeping shipping and service response times short for departments across the region. The company serves fire departments and first responder organizations across Ontario and Canada, supported by sales representatives stationed throughout the province. Get in touch through our Contact page or see directions to our head office.

A.J. Stone partners with leading fire service manufacturers, including MSA (MSA G1 and MSA SCBA systems), Task Force Tips nozzles and monitors, Innotex firefighter bunker gear, Enforcer CAFS and foam, Paratech rescue equipment, LION training tools, Seek Thermal cameras, Kuriyama fire hose, Streamlight lighting, and Circul-Air PPE cleaning and drying equipment. Carrying this range lets us outfit a department across nearly every equipment category rather than specializing narrowly in one. See our full Vendors page to browse by brand.

A.J. Stone supplies a full range of firefighting and first responder equipment, from SCBA and bunker gear to turnout gear, firefighting foam, fire hose, thermal imaging cameras, rescue tools, and gear care equipment like turnout gear extractors and PPE drying cabinets. The goal is not specializing in one category, it is outfitting a department's full operation, from suppression through decon and gear maintenance. Browse the full products catalog to see the range.

A.J. Stone's team includes multiple factory-trained repair and service technicians who handle both in-house and mobile maintenance and repairs, alongside dedicated customer service staff who help build custom quotes for departments. The company's guiding approach is "we service what we sell," meaning support does not end once equipment ships out.

The clearest recognition is the Ontario Association of Fire Chiefs' Alf Stone Award, named for the company's founder and first presented to him in 2002. The OAFC continues to award it annually to individuals who have made outstanding contributions to Ontario's fire service, and the Stone family continues to support OAFC programs. Beyond that, A.J. Stone's work has been covered editorially in Fire Fighting in Canada and by the International Association of Fire Fighters in connection with the Sault Ste. Marie PFAS-free gear deployment, and the company is listed in the OAFC buyers guide and the Fire Fighting in Canada supplier directory.

The most significant is an equity partnership: in April 2025, A.J. Stone announced a strategic partnership with Sani Gear Inc., a Canadian PPE cleaning, inspection, and repair company, acquiring a 50 percent ownership stake. That lets us offer fire departments a complete PPE lifecycle service, from gear selection and measurement through cleaning, inspection, and repair. Separately, A.J. Stone holds distributor and co-marketing relationships across its vendor roster, including MSA, Task Force Tips, Paratech, Innotex, Enforcer, LION, Seek Thermal, NRS Rescue, Streamlight, and Kuriyama. The Sani Gear partnership is distinct from those in that it expands the company's service capability rather than its product catalogue.

In May 2024, A.J. Stone supplied Sault Ste. Marie Fire Services with PFAS-free bunker gear, outfitting all 80 frontline firefighters with INNOTEX gear. The deployment made IAFF Local 529 the first Canadian IAFF affiliate to wear PFAS-free turnout gear, and was covered by Fire Fighting in Canada. A.J. Stone Fire Service Specialist Steve Dionne worked with the department for roughly 18 months to get the transition done.

A.J. Stone works with fire departments of all sizes across Ontario, from smaller township departments such as North Dumfries Fire Department, Douro-Dummer Fire Services, and Middlesex Centre Fire Department to larger municipal fire services like the Toronto Fire Service, Ottawa Fire Service, Hamilton Fire Department, Mississauga Fire and Emergency Service and Brampton Fire and Emergency Service.

A.J. Stone has been recognized by the manufacturers it represents across more than two decades. INNOTEX named the company a Preferred Dealer in 2014, 2015, and 2016, and an Elite Dealer in 2017, 2018, 2019, and 2025. From MSA, A.J. Stone received the President's Sales Award Canada in 2008 and 2012, the Pinnacle President's Award Canada in 2003, and the Pinnacle Sales Award in 2002.

The A.J. Stone team continues to be led by the Stone family, with Mike Stone serving as President and Chief Executive Officer (CEO) and Dan Stone as Senior Vice President (VP) and Chief Operating Officer (COO). In December 2022, Michelle O'Hara joined the executive leadership team as Vice President of Operations, a newly established role overseeing day-to-day operations, strategy, and organizational structure. She came to A.J. Stone after more than a decade with the Ontario Association of Fire Chiefs, most recently as its Executive Director.

A.J. Stone's team spans several groups: a family ownership group leading a business now in its third generation, a network of fire service sales specialists stationed across Ontario, a management team, sales and account coordinators, a service team of factory-trained technicians, plus accounting and warehouse staff. That range, from the founding family through dedicated regional sales reps, reflects a company still structured around direct relationships with departments rather than call-centre-style support.
