CSLB C-39 Roofing ContractorSafety and RepairEasy
A roofing contractor is setting up a ladder to access a roof with a 15-foot eave height. According to Cal/OSHA regulations, what is the minimum distance the ladder's side rails must extend above the landing surface?
- A2 feet
- B3 feet
- C1 foot
- D4 feet
Show answer & explanationAnswer & explanation
Correct answer: B. 3 feet
Cal/OSHA requires that the side rails of a ladder used to access an upper landing surface extend at least 3 feet above that landing surface to provide a secure handhold for safe transition.
Why the other options are wrong
- A. 2 feet is less than the minimum 3 feet required by Cal/OSHA for ladder extension above a landing.
- C. 1 foot is insufficient for a safe transition and does not meet Cal/OSHA requirements.
- D. 4 feet would provide additional safety but is not the minimum requirement; 3 feet is the specified minimum.
Cal/OSHA Ladder Extension
Ladder side rails must extend at least 3 feet above the upper landing surface for safe access.
- Applies to ladders used for accessing elevated surfaces.
- Provides a stable handhold for stepping on/off the ladder.
- Aids in maintaining balance during transition.
Memory trick: Three feet high, for a safe sky.
