Section 1509 requires every construction employer, on top of the IIPP, to adopt which written document?

Explanation

Section 1509(b) requires every construction employer to adopt a written Code of Safe Practices relating to its own operations, containing language equivalent to the relevant parts of Plate A-3 in the Appendix. The other three are real California documents produced by other sections: the emergency action plan comes from section 3220 and only where that standard applies; the heat illness prevention plan is section 3395(i) and is owed by outdoor employers, not by construction employers as such; and a site-specific fall protection plan is permitted under section 1671.1 as a narrow alternative where conventional fall protection is infeasible. None of them is what section 1509 asks for.
