Who this module is for

AFS fabricates the flashing. Installing it, and keeping that jobsite safe, is the installing contractor's work.

29 CFR 1926.20(b)(1) makes it the responsibility of the employer to start and keep up the safety programs the construction rules require.

This module is written for that contractor and crew. Nothing here describes an AFS safety program.
