Dear Mr. Shelly:

Thank you for your letter of July 1, 1982, concerning handrail and railing clearance for stanchion-mounted lights on stairways and platforms. Your letter was referred to this office for reply.

The OSHA National Office concurs with the clearance interpretation as stated in our Chicago Regional Office's May 10, 1979 letter. Accordingly, OSHA's nationwide interpretive position is the following:
A handrail as used on stairs, incline ramps, fixed industrial stairs, ships ladders, and other similar types, where the handrail is used to assist in maintaining balance in traversing from one elevation to another, should be designed to maintain the desired clearance. OSHA STD 1-1.6 (enclosed) allows 1-½-inch clearance.

Where railings are used on platforms and other surfaces to act as a perimeter guard to prevent falls from working and walking surfaces, the maintaining of the clearance is not as important. Therefore, it should not be considered a violation of the standard to mount lighting stands to the top railing and toeboard to illuminate the platform.
Should you have any further questions, please do not hesitate to contact [the Office of General Industry Enforcement at (202) 693-1850].
