§ 1960.29 Accident investigation.

(a) While all accidents should be investigated, including accidents involving property damage only, the extent of such investigation shall be reflective of the seriousness of the accident.

(b) In any case, each accident which results in a fatality or the hospitalization of three or more employees shall be investigated to determine the causal factors involved. Except to the extent necessary to protect employees and the public, evidence at the scene of an accident shall be left untouched until inspectors have an opportunity to examine it.
