The employer must provide ways for employees or employee representatives, or both to participate in developing and periodically reviewing programs and policies adopted to comply with this subpart.(d)Multi-employer worksites -(1)Host employer responsibilities. The host employer's responsibilities are to: (i) Inform all employers at the worksite about the content of the fire safety plan including hazards, controls, fire safety and health rules, and emergency procedures;(ii) Make sure the safety and health responsibilities for fire protection are assigned as appropriate to other employers at the worksite; and(iii) If there is more than one host employer, each host employer must communicate relevant information about fire-related hazards to other host employers.
