Rockwell Mining, LLC has submitted a petition to the Mine Safety and Health Administration (MSHA) to modify an existing safety standard for their Coal Branch No. 1 Mine in West Virginia. The company wants permission to use specific Powered Air Purifying Respirators (PAPRs) underground, which are not MSHA-approved but considered intrinsically safe by the company. These respirators, made by 3M and CleanSpace, offer constant airflow and protection, especially benefiting miners with facial hair or those who struggle with tight-fitting masks. The petition outlines detailed training, examination, and maintenance requirements to ensure the equipment is used safely.
Simple Explanation
Rockwell Mining wants to use special kinds of masks in a mine that help people breathe more easily, even if they have beards or don't like tight masks. But these masks haven't been officially approved yet, so they need permission to use them safely.
