Respiratory Protection Resources for Mine Workers
Current regulations and guidelines require coal mine operators in the United States to provide respirators to each miner. Each underground coal miner must have a self-contained self-rescuer (SCSR), also referred to as closed-circuit escape respirator (CCER) unit. Title 30, Code of Federal Regulationsexternal icon (30 CFR) §75.1714 provides safety standards for underground coal mines. The regulation requires that each person in an underground coal mine wear, carry, or have ready access to a unit. Coal mine operators should only provide units approved by NIOSH and the Mine Safety and Health Administration (MSHA). NIOSH NPPTL, in cooperation with MSHA, conducts an ongoing, long-term field evaluation of SCSR and CCER units. This evaluation assesses the units’ reliability and performance while deployed in underground coal mines.
View the results of NIOSH’s study of SCSR and CCER units deployed in U.S. underground coal mines. The ongoing study provides performance, reliability, and user maintenance compliance data on field-deployed SCSR units. View the mining PPE CASE reports to learn more.

Understanding the Breathing Gas Capacities (ratings) of Escape Respirators for Mineworker Use
DHHS (NIOSH) Publication Number 2013-148 (May 2013).
This publication helps workers understand the meaning of breathing gas capacity of a jointly approved NIOSH and MSHA CCER. Understanding the uses and limitations of the CCER is important in planning for an escape during a mine emergency.
