A solar technician is working on a residential rooftop using an extension ladder to access the work area. The eave height is 18 feet. According to safety regulations, what is the minimum safe working length for the ladder to extend above the roof's bearing point?
- A3 feet
- B1 foot
- C2 feet
- D4 feet
Show answer & explanationAnswer & explanation
Correct answer: A. 3 feet
OSHA regulations, and generally accepted safety practices, require that ladders used to access an upper landing surface must extend at least 3 feet above that surface. This provides a stable handhold for ascending and descending.
Why the other options are wrong
- B. This is insufficient for a safe handhold.
- C. This is less than the minimum required extension for safety.
- D. While safer, this is not the minimum required extension; 3 feet is the minimum.
Ladder Extension Rule
When using an extension ladder to access an upper landing surface, the ladder must extend at least 3 feet above that surface.
- Ensures a stable handhold for safe transfer.
- Applies to all ladders used for accessing elevated platforms.
- Prevents falls during ascent and descent.
Memory trick: Three feet up, you're safe and sound, for climbing ladders all around.
