(a) Working platforms that contain overhead structures which restrict emergency egress; and
(b) Single-point suspended working platforms.
(2) You must make sure each person on the working platform is provided with a fall arrest system that:
(a) Meets the requirements of Appendix C—Personal fall arrest system, WAC
296-24-88050, found in the General safety and health standards, chapter
296-24 WAC; and
(b) Uses a horizontal lifeline or direct connection anchorage on platforms that contain overhead structures which restrict emergency egress.
(3) You must make sure platforms suspended by two or more wire ropes are provided with vertical lifelines if failure of one wire rope or suspension attachment will cause the platform to upset.
