(d) Inspection, maintenance, and repair. The employer must ensure:
- (1) Walking-working surfaces are inspected, regularly and as necessary, and maintained in a safe condition;
- (2) Hazardous conditions on walking-working surfaces are corrected or repaired before an employee uses the walking-working surface again. If the correction or repair cannot be made immediately, the hazard must be guarded to prevent employees from using the walking-working surface until the hazard is corrected or repaired; and
- (3) When any correction or repair involves the structural integrity of the walking-working surface, a qualified person performs or supervises the correction or repair.
