- A3 feet
- B6 feet
- C4 feet
- D1 foot
Show answer & explanationAnswer & explanation
Correct answer: A. 3 feet
Cal/OSHA regulations require 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 safe handhold for workers.
Why the other options are wrong
- B. Extending the ladder 6 feet is excessive and not the minimum requirement specified by Cal/OSHA regulations.
- C. While extending the ladder further may provide additional safety, 4 feet is not the minimum required by Cal/OSHA.
- D. This extension is insufficient for safe access and egress according to Cal/OSHA standards.
