Section 22 Worker overexposure

(1) If a worker may be exposed to an airborne concentration that is more than the occupational exposure limit of a substance, the employer must conduct measurements of the concentrations of that substance at the work site.

(2) If a worker is exposed to more than the occupational exposure limit of a substance, the employer must immediately

(a) identify the cause of the overexposure,

(b) protect the worker from any further exposure,

(c) control the situation so that no other workers are exposed to the substance at airborne concentrations that are more than the occupational exposure limit, and

(d) explain to the worker the nature and extent of the overexposure.

(3) As soon as reasonably practicable, an employer must inform the joint work site health and safety committee, if there is one, in writing, that a worker has been exposed to more than the occupational exposure limit of a substance and the steps taken to control the overexposure.
