OSHA 1926.451(e)(1): safe access to scaffold platforms
Under 29 CFR 1926.451(e)(1), when a scaffold platform is more than 2 feet above or below a point of access, workers must use a ladder, stair tower, ramp, walkway, integral access or direct access from another surface. Crossbraces may not be used as a means of access.
Official text
(e)(1) When scaffold platforms are more than 2 feet (0.6 m) above or below a point of access, portable ladders, hook-on ladders, attachable ladders, stair towers (scaffold stairways/towers), stairway-type ladders (such as ladder stands), ramps, walkways, integral prefabricated scaffold access, or direct access from another scaffold, structure, personnel hoist, or similar surface shall be used. Crossbraces shall not be used as a means of access.Read the full section on eCFR
(e)(2)(ii) Hook-on and attachable ladders shall be positioned so that their bottom rung is not more than 24 inches (61 cm) above the scaffold supporting level;Read the full section on eCFR
(e)(2)(iii) When hook-on and attachable ladders are used on a supported scaffold more than 35 feet (10.7 m) high, they shall have rest platforms at 35-foot (10.7 m) maximum vertical intervals.Read the full section on eCFR
What it requires, in plain English
- Access is required when the platform is more than 2 feet (0.6 m) above or below the point of access.
- Acceptable means include portable, hook-on and attachable ladders, stair towers, ramps, walkways, integral prefabricated access, and direct access from another scaffold, structure or personnel hoist.
- Hook-on and attachable ladders have a bottom rung no more than 24 inches above the scaffold supporting level.
- On supported scaffolds more than 35 feet high, hook-on and attachable ladders have rest platforms at 35-foot maximum vertical intervals.
Where it shows up on site
- Workers climbing the crossbraces of a frame scaffold to reach the deck
- A hook-on ladder that stops well above the ground or mudsill
- No ladder or stair tower at all on a scaffold run, so workers climb the end frames
Verify on site before you call it
A photo rarely shows every fact a standard depends on. Confirm these in person before treating the condition as a violation:
- How far above or below the point of access is the platform?
- Is the worker erecting or dismantling the scaffold, where 1926.451(e)(9) access rules apply instead?
- Is there a ladder, stair tower or direct access point outside the photo?
- How high is the scaffold, and does the ladder need rest platforms?
Typical corrective actions
- Stop climbing on crossbraces and provide a ladder, stair tower or other listed means of access.
- Install a hook-on or attachable ladder designed for the scaffold type, with the bottom rung within the allowed distance of the supporting level.
- Add rest platforms where the ladder serves a tall supported scaffold.
- Brief the crew on the designated access points for the scaffold.
Common questions
Can workers climb scaffold crossbraces?
No. 1926.451(e)(1) states that crossbraces shall not be used as a means of access. A ladder, stair tower, ramp, walkway, integral access or direct access from another surface must be used instead.
When does a scaffold need a ladder or stair?
When the platform is more than 2 feet (0.6 m) above or below the point of access, one of the access methods listed in 1926.451(e)(1) is required.
Turn the observation into a notice
Record what the photo shows, confirm the on-site checks above, and identify the responsible company and due date. Use the fillable construction safety notice template or follow aworked example from observation to verified fix. Cirqify can draft the notice from your circled photo for you to review.
