OCCUPATIONAL SAFETY AND HEALTH
1926 Subpart T
Overview for Subpart T Demolition
T-1 What are the serious most frequently cited demolition violations?
- Not performing a written engineering survey of the structure before commencing demolition work [1926.850(a)].
- Not providing fall protection for employees exposed to wall openings [1926.850(g)].
- Not providing shoring or bracing for walls to prevent premature collapse [1926.850(b)].
- Not properly inspecting and maintaining stairways and ladders in safe conditions for employee use [1926.851(b)].
- Not properly testing and removing hazardous materials from within the structure before commencing demolition work [1926.850(e)]; and not providing sidewalk shed covers to protect employee entrances to structure [1926.850(h)].
T-2 What are some effective control measures that can be used to protect employees from the hazards presented in T-1 above?
- First, the engineering survey needs to be done to determine areas where premature collapse may occur. While this survey is being done, the presence of hazardous materials needs to be noted including whether asbestos or lead is present. If hazardous materials are present then these hazards will need to be included in the work scheduling before the demolition work can begin. Knowledge of the structure's weak points and the presence of hazardous materials including the contents of equipment within the structure prior to beginning demolition work is essential for providing a safe work environment. See 1926.850 preparatory operations, 1926.62 lead, 1926.1101 asbestos and 1926.150 fire protection for more specific criteria.
- Fall protection measures are necessary for employees who will be using stairs, ladders, or working near wall openings (see illustration T-1). The measures required in Subpart M - Fall Protection and Subpart X - Stairways and Ladders will provide further clarification of what measures are necessary to assure employees are protected from falling.
- Safe entrance into the structure to be demolished is necessary to protect employees from objects falling onto them as they enter to begin work. This overhead shed protection needs to extend at least 8 feet (2.46 m) out from the structure to prevent workers from being struck by falling objects. See 1926.850(k) for specific criteria.
All guard rails must be able to withstand 200 pounds lateral pressure at the top rail.
