TIPS ON SCAFFOLD SAFETY CHECK SAFETY CODES: OSHA, state and local safety codes should be consulted; and approval obtained from Building Safety and Industrial Commission on scaffold tips. INSPECT AND CHECK: Take no chances. Inspect the scaffold set up after erection and daily while in use. Don't remove or allow removal of, any parts without the OK from the proper authorities. When wire rope is used, inspect it on each job. DON'T SHORT-CHANGE BRACING: Use bracing at all points provided; add extra braces if needed to insure stability. TIE SCAFFOLD TO THE BUILDING: Scaffolding should be tied to the struc- ture using heavy wire or tie-in devices. The first vertical tie should be at the maximum height of 4 times the narrowest base dimension. Additional ties are not to exceed 26 feet vertically. Maximum horizontal distance between ties is not to exceed 30 feet. USE METAL CATWALKS, PLATFORMS; Where available. If wood plank is used, it must be scaffold grade or better. Inspect thoroughly before every job to make sure it is free from breaks, knots, cracks or warpage. Decking should be full width. DON'T RIDE MOVING SCAFFOLD; and remember scaffold units are limited in height to 4* times their narrowest base dimension (unless base is widened by outriggers, or more end frames; or tied into building.) Always keep casters locked. (except to re-spot) PROTECT WORKING LEVELS: Use overhead canopies to protect workers on lower work levels when work is being done overhead. Rope off unsafe areas underneath scaffold or provide wire mesh around work area. USE DOUBLE GUARD RAILS; and toeboards on exposed sides at platform heights of 6 feet or more.
