WAC 296-155-795

Removal of walls, masonry sections, and chimneys.

(1) You must not permit masonry walls, or other sections of masonry, to fall upon the floors of the building in such masses as to exceed the safe carrying capacities of the floors.
(2) You must not permit any wall section, which is more than one story in height, to stand alone without lateral bracing, unless such wall was originally designed and constructed to stand without such lateral support, and is in a condition safe enough to be self-supporting. You must leave all walls in a stable condition at the end of each shift.
(3) You must not permit employees to work on the top of a wall when weather conditions constitute a hazard.
(4) You must not cut or remove structural or load-supporting members on any floor until all stories above such a floor have been demolished and removed. This provision must not prohibit the cutting of floor beams for the disposal of materials or for the installation of equipment, provided that the requirements of WAC 296-155-790 and 296-155-800 are met.
(5) You must plank solid floor openings within 10 feet of any wall being demolished, except when employees are kept out of the area below.
(6) In buildings of "skeleton-steel" construction, the steel framing may be left in place during the demolition of masonry. Where this is done, you must clear all steel beams, girders, and similar structural supports of all loose material as the masonry demolition progresses downward.
(7) You must provide walkways or ladders to enable employees to safely reach or leave any scaffold or wall.
(8) You must not demolish walls, which serve as retaining walls to support earth or adjoining structures, until such earth has been properly braced or adjoining structures have been properly underpinned.
(9) You must not use walls, which are to serve as retaining walls against which debris will be piled, unless capable of safely supporting the imposed load.
