PPE must meet Subpart E, with 1926.95(d) governing employer payment for PPE this subpart requires, including fall protection, electrical protective equipment and flame-resistant and arc-rated gear. Personal fall arrest systems must meet Subpart M; where employees face flame or arc hazards identified under 1926.960(g)(1), fall arrest equipment must still pass a drop test equivalent to (b)(2)(xii) after exposure to an arc with heat energy of 40±5 cal/cm2. Work-positioning body belts and positioning straps must meet design and test criteria: hardware of drop-forged, pressed or formed steel or equivalent, with a corrosion-resistant, smooth, edge-free finish; buckles withstand an 8.9-kN (2,000-lbf) tension test with no more than 0.4 mm (0.0156 in) permanent deformation; D rings a 22-kN (5,000-lbf) tensile test without cracking or breaking; snaphooks a 22-kN (5,000-lbf) tension test without failure. Leather may be used but never alone as a load-bearing component; plied fabric must have no exposed raw edges or separating plies. Positioning straps must pass a dielectric test of 819.7 V AC per cm (25,000 V per ft) for 3 minutes, a leakage test at 98.4 V AC per cm (3,000 V per ft) with leakage of at most 1 mA, tension tests of 20 kN (4,500 lbf) without buckle holes and 15 kN (3,500 lbf) with them, a 4.4-kN (1,000-lbf) buckle-tear test, and the Table V-1 flammability test (self-extinguishing and still holding a 100-kg load after a 5-second flame). Belt cushions are at least 76 mm (3 in) wide with no exposed rivets inside; the centre 100 mm (4 in) of the back between D rings is kept free of tool loops; D-ring bars have liners; snaphooks are locking, needing 6.7 to 17.8 N (1.5 to 4 lbf) to release the lock, and, with the lock released, the keeper must stay shut up to 11.2 N (2.5 lbf) yet begin opening by 17.8 N (4 lbf). Drop tests use a 100-kg (220.5-lbm) mass (scaled up for workers over 140 kg fully equipped, equipped mass divided by 1.4) falling 1 m (39.4 in); straps must arrest it with no more than 17.8 kN (4,000 lbf). Equipment meeting ASTM F887-12e1 is deemed compliant for users up to 140 kg (310 lbm). Work-positioning equipment is inspected before use each day and not used if unsafe (Appendix F gives guidelines). Fall arrest systems are used per 1926.502(d). Employees in aerial lifts use fall restraint or personal fall arrest (1926.453(b)(2)(v) does not apply). Employees more than 1.2 m (4 ft) up on poles, towers or similar structures use fall arrest, work-positioning or fall restraint unless other Subpart M protection exists. Since April 1, 2015, qualified employees climbing or changing location must use fall protection unless the employer shows it is infeasible or a greater hazard; trainees and unqualified employees always need it above 1.2 m. Since April 1, 2015 work-positioning systems are rigged for free falls of no more than 0.6 m (2 ft). Work-positioning anchorages must hold the greater of 13.3 kN (3,000 lbf) or double the impact load a fall could produce. Non-locking or undesigned snaphooks may not be connected to webbing, rope or wire rope, to each other, to an occupied D ring, to a horizontal lifeline, or to incompatible objects.
