What 29 CFR 1910.30 requires (plain English)
29 CFR 1910.30 requires general-industry employers to train workers about fall and equipment hazards before those workers are exposed to them. It is the training leg of the general-industry walking-working-surfaces framework, the counterpart to construction's 1926.503, completing the duty (1910.28), criteria (1910.29), training (1910.30) structure.
Under 1910.30(a), before any employee is exposed to a fall hazard, the employer must provide training, delivered by a qualified person, for each employee who uses personal fall protection systems or who is otherwise required to be trained. The training must ensure the worker understands the nature of fall hazards in the work area, the correct procedures for using the fall protection systems, and how to maintain, inspect, and store the equipment.
A separate provision, 1910.30(b), requires training on the equipment hazards addressed elsewhere in Subpart D: such as dockboards, rope descent systems, and designated areas. Retraining is required whenever the employer has reason to believe a worker lacks the understanding or skill the training was meant to provide, for example after changes in the workplace or equipment, or when a worker's behavior shows the earlier training did not hold.
