OSHA 10-Hour Construction ReviewStairways and LaddersMedium
A worker is using a stepladder on a construction site. To ensure stability and prevent tipping, what is the maximum height from the top of the stepladder that a worker is permitted to stand, according to OSHA guidelines?
- AThe top cap
- BAny step as long as three-point contact is maintained
- CThe second step from the top
- DThe third step from the top
Show answer & explanationAnswer & explanation
Correct answer: C. The second step from the top
OSHA prohibits standing on the top cap or the step immediately below the top cap (the first step from the top) of a stepladder. Therefore, the highest permissible standing step is the second step from the top.
Why the other options are wrong
- A. Standing on the top cap is strictly prohibited as it can lead to loss of balance and falls.
- B. Three-point contact is important, but it does not override the prohibition of standing on the top two steps of a stepladder.
- D. While safe, this is not the maximum permissible height; workers can stand one step higher.
Stepladder Top Step Rule
Workers are prohibited from standing on the top cap or the step immediately below the top cap of a stepladder.
- Ensures stability and prevents tipping.
- Applies to all stepladders.
- The 'second step from the top' is the highest safe standing point.
Memory trick: Top two steps are a no-go, for safety, stand below!
