What safety equipment is required for underground use?
A. Personal protective equipment should include safety eyewear, chemical resistant gloves, and long-sleeve work clothes. Adequate ventilation should also be employed so that vapor levels do not exceed recommended Occupational Safety & Health Administration (OSHA) guidelines. If vapor levels are expected to exceed these guidelines, use National Institute for Occupational Safety & Health (NIOSH)/Mine Safety & Health Administration (MSHA) approved, positive pressure supplied air respirator.
