Product Specifications

For: CSE Self Contained Self Rescuer model SLRD Justification:

This action is for the purchase of SLRD Self Contained Self Rescuers (SCSR). SCSRs are required for any inspector who goes underground. Under the regulations in 30 CFR Part 75, these units must by MSHA and NIOSH approved units. Working in a coal mine subjects personnel to a harsh environment where the average mine height is approximately 42 inches, there is no light, the surfaces are wet and slippery, and the average temperature is approximately 55 degrees. There is usually only 2 means into or out of the mine. The environment may contain methane and other harmful gasses. In the event of an emergency, the breathing environment may become contaminated with carbon monoxide, methane, carbon dioxide and other noxious gasses. In such emergency situations the MSHA personnel must depend on the Self Contained Self Rescuers for a breathable mixture of air that will permit them adequate time to safely exit the mine.

Moreover, space and weight concerns are of paramount importance to MSHA inspectors. MSHA inspectors frequently need to work in very tight spaces, many of which are less than 30 inches tall. A unit that be securely worn on the belt is very important. In addition, MSHA inspectors need to carry a significant amount of equipment, often weighing as much as 45 pounds. As a result, smaller, lighter equipment lessens the load that inspectors need to carry. This is not just a question of comfort but of safety.
