Ramps and Walkways
Scaffold ramps and walkways must meet the following requirements:
- Ensure ramps and walkways 6 feet or more above lower levels have appropriate guardrails.
Ramps 6 feet or more above lower levels must have guardrails.
- Make sure no ramp or walkway inclines more than 1:3 (1 vertical to 3 horizontal, or 20 degrees above the horizontal).
- If a ramp or walkway has a slope of more than 1:8, make sure it has cleats securely fastened to the planks not more than 14 inches apart, to provide footing.
Direct Access
Check that direct access to or from another surface is permitted only when the scaffold is not more than 14 inches horizontally and not more than 24 inches vertically from the other surface.
Erectors and Dismantlers
- While inspecting during scaffold erection and dismantling, make sure safe access for employees erecting or dismantling supported scaffolds is provided where it is feasible, and where it does not create a greater hazard.
- Ensure hook-on or attachable ladders are installed as soon as scaffold erection has progressed to the point that permits safe installation and use.
- When erecting and dismantling tubular, welded-frame scaffolds, and end frames are used as climbing devices for access, make sure:
- Horizontal members are parallel, level, and not more than 22 vertical inches apart.
- Horizontal members are erected in a manner that creates a usable ladder and provides good hand hold and foot space.
- Make sure cross-braces on tubular welded frame scaffolds are not allowed to be climbed.
