Guard openings to hoppers and chutes.

(1) You must guard all openings to hoppers, chutes, and elevator-type conveyors to prevent workers from:
(a) Falling or stepping into them.
(b) Making any kind of bodily contact with conveyors.
Grating provided at floor level with no openings larger than two inches (50 mm) that is strong enough to withstand any load of personnel or trucks that may be imposed upon it is acceptable guarding.
(2) You must do all of the following when dumping operations use chutes or hoppers that are flush with the floor and their use cannot be guarded:
(a) Place a temporary guardrail around ground or floor-level hoppers when dumping operations are not in progress.
(b) Post warning signs in a conspicuous location alerting personnel to the presence of an open pit in order to protect employees when dumping operations are in progress.
For guardrail requirements see, Railing, toeboards, and cover specifications, WAC 296-24-75011.
