What protective clothing and equipment must surface coal mine employees wear under 30 CFR 77.1710? Answer in under 100 words.

Under 30 CFR 77.1710, every employee in a United States surface coal mine (or the surface work areas of an underground coal mine) must wear MSHA-required protective gear: face shields or goggles when welding, cutting, or facing eye hazards; full-body coverings such as chemical-resistant suits or coveralls; protective gloves unless entanglement creates a greater hazard; a hard hat or hard cap where falling objects threaten; protective footwear such as steel-toed boots; snug-fitting clothing near moving machinery; full-body harnesses with lifelines at fall hazards; lifejackets where water immersion is possible; and seatbelts in ROPS-equipped vehicles.

Details / How it works

Section 77.1710 requires each employee working in a surface coal mine, or in the surface work areas of an underground coal mine within the United States, to wear protective clothing and devices per MSHA standards:

  • Eye protection: Face shields or goggles (e.g., welding helmets, safety glasses) when welding (arc or oxy-fuel), cutting, working with molten metal, or when flying particles, intense light, or chemical splashes exist.
  • Body protection: Suitable full-coverage clothing (e.g., chemical-resistant suits, aprons, or coveralls) when handling corrosive or toxic substances or skin-injury materials.
  • Hand protection: Gloves appropriate to the hazard (leather, rubber, cut-resistant, or insulated).
  • Head protection: A suitable hard hat or hard cap that is impact- and penetration-resistant.
  • Foot protection: Steel-toed boots, metatarsal guards, or slip-, puncture-, and impact-resistant footwear.
  • Fall protection: Safety belts (full-body harnesses) and lifelines where there is danger of falling; a second person (safety attendant) shall tend the lifeline when bins, tanks, or other dangerous areas are entered.
  • Flotation: Lifejackets or life belts where there is danger from falling into water.
  • Vehicle restraints: Seatbelts (operator restraint systems) in vehicles where overturning danger exists and rollover protective structures (ROPS) are provided.

Numbers & thresholds

Subsection Hazard trigger Required equipment
(a) Welding, cutting, molten metal, eye hazards Face shields, goggles, welding helmets
(b) Corrosive/toxic substances Chemical-resistant suits, aprons, coveralls
(c) Hand-injury materials Leather, rubber, cut-resistant, or insulated gloves
(d) Falling objects Hard hat or hard cap
(e) Foot hazards Steel-toed boots, metatarsal guards, slip/puncture/impact-resistant footwear
(f) Moving machinery Snug-fitting (non-loose) clothing
(g) Danger of falling Full-body harness plus lifeline with attendant
(h) Water immersion risk Lifejackets or life belts
(i) Vehicle overturning with ROPS Seatbelts (operator restraint systems)

Exceptions & edge cases

  • Glove exception: Gloves are not worn where they would create a greater hazard by becoming entangled in the moving parts of equipment.
  • Hard hat painting: If a hard hat or hard cap is painted, nonmetallic based paint shall be used to avoid compromising electrical insulation or structural integrity.
  • Lifeline attendant: When bins, tanks, or other dangerous areas are entered, a second person (safety attendant) must tend the lifeline.
  • Seatbelt condition: Operator restraint systems apply specifically where a vehicle presents overturning danger and rollover protective structures (ROPS) are provided.

Authority: Section 101(a) of the Federal Coal Mine Health and Safety Act of 1969; originally published in the Federal Register on May 22, 1971 (36 FR 9382), with later amendments (36 FR 13143, July 15, 1971; 39 FR 7176, February 25, 1974).
