The ladders shall be constructed of adequately strong materials with rungs placed at equal intervals of _____________ apart and securely fastened and maintained in good condition at all times.

• A. 20 centimeters
• B. 25 centimeters
• C. 35 centimeters
• D. 40 centimeters

Answer: (C)

Safe ladder use relies on rungs being placed at a regular, comfortable distance so you can step securely with steady rhythm. About 35 centimeters (roughly 14 inches) between rungs provides enough room for a typical boot to land firmly while keeping your stride manageable. If the spacing were much smaller, climbing would feel cramped and require more rungs; if it were larger, each step would be harder to balance and could lead to slips. With rungs spaced at this interval and kept in good condition and securely attached, you get a reliable, steady climb that supports three-point contact and reduces the risk of falls.
