What it requires, in plain English
- A competent person inspects scaffolds and components for visible defects before each work shift.
- A new inspection is needed after any occurrence that could affect structural integrity.
- Any part damaged or weakened below the required strength is immediately repaired or replaced, braced, or removed from service until repaired.
- Erecting, moving, dismantling or altering a scaffold happens only under the supervision and direction of a qualified competent person.
Where it shows up on site
- A scaffold struck by equipment and put back in use without a check
- Bent frames, cracked planks or missing pins on a working scaffold
- A scaffold tag that has not been updated for the current shift
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:
- Who is the designated competent person for scaffolds on this site?
- Was the scaffold inspected before this work shift?
- Has anything happened since the last inspection, such as an impact, high wind, or a modification?
- Are the defects visible in the photo on a component that is in use?
Typical corrective actions
- Have the competent person inspect the scaffold before further use this shift.
- Remove damaged or weakened components from service and repair, replace or brace them.
- Re-inspect after any impact, alteration or other event that could affect structural integrity.
- Limit erection, moving, dismantling and alteration to trained employees under the competent person’s direction.
Common questions
How often does OSHA require scaffolds to be inspected?
Under 1926.451(f)(3), before each work shift and after any occurrence that could affect the scaffold’s structural integrity. The inspection is for visible defects and must be done by a competent person.
Does OSHA require scaffold tags?
The cited paragraph requires the inspection itself, by a competent person, before each shift. It does not mention tags; many sites use them to show inspection status, so check your site or company program.
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.
