Q: Is it acceptable to tie off
inside a basket (lift) using a retractable safety cable and harness?
A: It is a requirement to tie off when using an aerial lift in any form other than a properly guarded scissors lift. OSHA requirements when using the personal fall arrest system state, when stopping a fall:
(iii) be rigged such that an
employee can neither free fall more than 6 feet (1.8 m), nor contact any lower
level. [1926.502(d)(16)(iii)]
