Which statement describes a key safety rule for ladders on deck?

• A. Maintain three points of contact and keep the ladder at a safe angle.
• B. Climb as fast as possible to minimize time on the ladder.
• C. Only use ladders when fully loaded with gear.
• D. Ladders can be used at any angle.

Answer: (D)

The key safety rule is to maintain three points of contact and set the ladder at a safe angle. Keeping three points of contact means you always have two hands and one foot, or two feet and one hand, on the ladder. This gives you stability and helps your weight stay centered as you climb or descend, reducing the chance you’ll slip off a rung. Setting the ladder at a safe angle—typically about 75 degrees, often described as a four-to-one ratio (for every four feet of ladder height, place the base about one foot from the deck)—helps prevent the ladder from slipping outward or tipping inward if the deck moves or you shift your weight. On a ship’s deck, where motion from waves or wind can happen, this stable setup is essential for keeping balance and control while climbing. Also ensure the ladder is secured at the top and bottom and that it extends a bit above the deck so you have something to hold onto when stepping off.

Climbing as fast as possible compromises balance and increases the risk of missing a rung or losing grip. Ladders should be used whenever needed whether lightly or heavily loaded, and they must not be used at any angle—only at a safe angle to maintain stability.
