Confined spaces represent a major health and safety risk for many workers. Before anybody enters a confined space, a system of procedures and precautions must be followed. It is essential that supervisors, attendants, and entrants all know the specifics of the space. It is also critical to have the correct equipment on hand to ensure worker safety.
A wide range of protective equipment is available for protecting entrants to confined space work areas. It is essential that each entrant has the correct equipment for the environment and is versed in its safe and effective use. | TNT Confined Space Cutter - CSC-40 | | Most advanced confined space cutter | | Internal safety bleed valve to prevent over pressurization | | Regrindable blades, extends blade life | | Anodized aluminum body | | Separate controller |

MSA Confined Space Equipment  To facilitate both entry into and exit from a confined space, it is necessary to have a proper retrieval system for both workers and equipment. Consisting of a heavy-duty lifeline, a tripod, and a personnel/material hoist, retrieval equipment is useful in lowering workers into a confined space environment, as it controls the
rate of descent and prevents accidental falls into the work area. Additional work hoists are frequently used to raise and lower tools and equipment.
MSA offers complete confined space entry kits for multiple confined space applications. Confined space kits with Lynx Rescuer allow for non-entry rescue of a confined space entrant. Tripod and davit kits allow for great portability. | The Lynx™ Rescuer | The Lynx™ Hoist | Harness | The Lynx™ Rescuer is a field resettable self-retracting lanyard with emergency rescue capability.
The Lynx Rescuer has a 4.5 feet per second locking speed and a built-in shock absorber that will limit fall arrest forces to 900 lbf. Each unit comes with 3/16" stainless steel cable and a forged steel swivel snaphook that contains a load indicator to make users aware that a fall has occurred on the Dynevac II. When the emergency rescue device is activated, the Dynevac II has the ability of retrieving a fallen or injured worker. | The Lynx™ Hoist is a rugged, versatile, and economical hoist for lifting, lowering, and positioning of personnel and materials. Designed for a maximum work load of 310 lbs for personnel (10:1 design factor) and 620 lbs for materials (5:1 design factor). All steel construction with an internal shock absorber that operates even when usable length of line is fully extracted. Loadlimiting clutch prevents loading hoist in excess of 620 lbs. Emergency drive allows manual bypass of the load-limiting clutch for extra lifting capacity. | The Pullover harness uses a patented design which eases donning and doffing. A single point shoulder strap adjuster and the choice of Qwik-Fit™, tongue or friction thigh strap
buckles, to adjust the harness snugly to the body. Integrated systems (harnesses with
shock absorbers) are available
upon request. All Pullover
harnesses meet or exceed ANSI Z359.1, ANSI A10.14, CSA and OSHA requirements. |  |  |  |
Portable Gas Detection Instruments Battery-powered, direct-reading portable gas detection instruments are considered by many experts to be the most practical devices for conducting spot checks of a confined space atmosphere. These monitoring devices, which are classified into two groups—single-gas instruments and multiple-gas instruments, typically monitor one or a combination of the following atmospheric conditions:
(1) Oxygen deficiency or enrichment
(2) The presence of combustible gas
(3) The presence of certain toxic gases For more info about gas detection please click here. | Single-Gas Monitors for Combustible Gases | Single-Gas Monitors for Toxic Gases | Multigas Monitors for Oxygen, Combustible and Toxic Gases | Single-gas instruments for monitoring combustible gases and vapors are generally calibrated on pentane or methane and are designed for general purpose monitoring of hydrocarbon vapors. Such instruments operate through the catalytic action of a heated platinum filament in contact with combustible gas. The filament is heated to operating temperature by an electric current. When the gas sample contacts the heated filament, combustion on its surface raises the temperature in proportion to the quantity of combustibles in the sample. A Wheatstone bridge circuit, incorporating the filament as one arm, measures the change in electrical resistance due to the temperature increase. This change indicates the percentage of combustible gas present in the sample. 
| Compact, battery-powered devices can be used to measure levels of carbon monoxide (CO), hydrogen sulfide (H2S) or other toxic gases, depending upon the model selected. Most toxic gas monitors use electrochemical cells. If the gas of interest enters the cell, the reaction produces a current output proportional to the amount of gas in the sample. With these instruments, audible and visible alarms sound if the gas concentration exceeds a preset level. These devices are well suited for use in confined spaces containing motors or engines, which can generate large quantities of CO, as well as in sewers, waste treatment plants and oil refineries which tend to have hazardous volumes of H2S and SO2 present. In recent years, infrared sensors have been developed for use in portable instruments, typically for detection of carbon dioxide (CO2) and hydrocarbons. | Toxic gases and vapors, which can be inhaled or absorbed through the skin, are frequently found in confined spaces. Sometimes these atmospheric hazards displace oxygen and may make the body incapable of maintaining respiration. Some toxic gases and vapors can also cause long-term physical damage to the body in cases of repeated exposure. A number of instruments are available to assist in toxic gas detection. Whereas most single-gas monitors operate in diffusion mode, some hand-held multigas instruments have built-in pumps to draw samples from the immediate area or from outside the confined space work area when used with sampling lines. The user views sensor readout on a digital display on the face of the instrument. Regardless of the number of sensors used, all sensors monitor and display readout continuously.
Diffusion-type instruments are available for simultaneously measuring the LEL of combustible gases, oxygen, and toxic levels (in parts per million) of H2S, CO, and other toxic gases. Alarms also alert the user to low and high oxygen levels. Remote sampling pump adapters are available to convert diffusion instruments into pumped instruments. |
