MSHA - SELF CONTAINED SELF RESCUERS

SCSRs are required to be worn by MSHA’s mine inspectors when going underground in mines for safety reasons. Also, in accordance with 30 CFR part 75 subpart R section 75.1714-1, self-rescue devices must be available for use by all persons entering coal underground mines and these devices must be approved by MSHA and the National Institute of Occupational Safety and Health (NIOSH) under 42 CFR Part 84.

In the event of a mine emergency, the breathing environment may become contaminated with carbon monoxide, methane, carbon dioxide, and other noxious gasses. In such emergency situations, MSHA personnel must depend on the SCSRs for a breathable mixture of air that will permit them adequate time to safely exit the mine. Space and weight considerations are of importance to MSHA mine inspectors for safety reasons. MSHA mine inspectors frequently need to work in very tight spaces, many of which are less than 30 inches in height. In addition, MSHA mine inspectors need to carry a significant amount of equipment, often weighing as much as 45 pounds or more. Smaller and lighter equipment lessens the total weight that MSHA mine inspectors need to carry which translates to increased safety.
