Under 29 CFR 1926.1053(b)(5)(i), what approximate setup ratio applies to an ordinary non-self-supporting portable ladder, excluding a wood job-made ladder with spliced side rails?
Correct Answer
A) 1 foot of horizontal setback per 4 feet of working length along the ladder
Under 29 CFR 1926.1053(b)(5)(i), the horizontal setback is approximately one quarter of the distance along the ladder from its foot to the upper support. Thus the indicated ratio is 1:4. Spliced-side-rail wood job-made ladders have a different rule in (b)(5)(ii). Source: https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.1053
