Dear Mr. Frederick:
This is in response to your letter of March 19 addressed to Mr. Gerald Reidy, Director, Office of Construction/Maritime Compliance Assistance, concerning head clearance requirements for fixed ladders used on FAA radio communication towers varying in height from 30 to 150 feet.
Regarding 29 CFR 1910.268(h) Telecommunications Ladders, the following clarifications are provided:
1. 29 CFR 1910.268(h) does not specifically cover clearances on the climbing side of fixed ladders, andThank you for your interest in occupational safety and health. If we may be of further assistance, please contact us.
2. 29 CFR 1910.268(a)(3) states in part, "Operations or conditions not specifically covered by this section are subject to all applicable standards contained in this Part 1910," therefore;
3. 29 CFR 1910.27(c)(1) Climbing Side Clearance, Fixed Ladders, copy enclosed, pertains to clearances on the climbing side of fixed ladders installed on FAA radio communication towers. That standard requires the clearance on the climbing side of a vertical fixed ladder to be 30 inches.
4. Also, enclosed is the newly released Occupational Safety and Health Administration standard "Walking and Working Surfaces and Personal Protective Equipment", 29 CFR 1910.23(c)(13) page 13399, and ANSI A14.3-1984, Section 126.96.36.199 which state that "When unavoidable obstructions are encountered, the minimum clearance may be reduced to 24 inches if deflection plates are provided".
5. If an Occupational Safety and Health Administration (OSHA) compliance officer were to observe conditions as described in item 4 above, a violation would be noted and classified as de minimis, with no abatement required and no penalty assessed. De minimis violations are explained by an enclosure from our Field Operations Manual.
