Button guide stabilization system.
(1) You must make sure the guide buttons are:
(a) Coordinated with the platform guide tracks and other platform-mounted equipment; and
(b) Located on the building so they properly engage the guide tracks mounted on the platform.
(2) You must make sure two guide buttons engage each guide track at all times except for the initial engagement.
(3) You must make sure guide buttons that extend beyond the face of the building have no sharp edges or points.
(4) You must make sure guide buttons do not interfere with the handling or operation of cables, suspension wire ropes and lifelines that may be in contact with the building face.
(5) You must make sure guide buttons, connections, and seals are either:
(a) Able to sustain, without damage, at least the weight of the platform; or
(b) Are prevented by the guide tracks or guide track connectors from having the weight of the platform and its attachments transmitted to them.
