Underground mines can use modern respirators without asking for special permission

The US Labor Department is proposing to let underground mines use a specific type of modern respirator. Mine operators will no longer need to ask for special permission every time they want to use these devices.

For decades, mine operators had to get a special waiver to use a specific type of advanced breathing equipment. This meant a slow, expensive process for every mine that wanted to upgrade its safety gear. This change means mines can adopt better technology faster, without bureaucratic delays.
