How high must ladders extend above a trench?

• A. At least 2 ft
• B. At least 3 ft
• C. At least 4 ft
• D. At least 5 ft

Answer: (B)

When working near trenches, it's critical for ladders to provide a safe means of access that ensures workers can enter and exit the trench securely. A ladder must extend at least 3 feet above the edge of the trench. This height facilitates safe access, allowing workers to grip the ladder above the trench's edge when climbing up or down. By extending at least 3 feet above the edge, it helps prevent slipping and falling, which can occur if a worker attempts to step off the ladder at the trench's edge without a secure handhold. This specification is crucial for adhering to safety regulations and promoting a safer work environment around excavations.
