Cal/OSHA requires every employer (including those in construction) to set up an effective Injury and Illness Prevention Program (IIPP). Tailgate safety training for workers is an integral part of an IIPP. Below are excerpts from Construction Safety Order §1509, which specifies IIPP requirements in the construction industry. The chart on the next page shows what an IIPP must include.

(a) Every employer shall establish, implement and maintain an effective Injury and Illness Prevention Program.
(b) Every employer shall adopt a written Code of Safe Practices which relates to the employer's operations.
(c) The Code of Safe Practices shall be posted at a conspicuous location at each job site office or be provided to each supervisory employee who shall have it readily available.
(d) Periodic meetings of supervisory employees shall be held under the direction of management for the discussion of safety problems and accidents that have occurred.
(e) Supervisory employees shall conduct "toolbox" or "tailgate" safety meetings, or equivalent, with their crews at least every 10 working days to emphasize safety.
