Why are a 75-degree angle and secure footing important when using ladders in exterior operations?

• A. To ensure stability and reduce fall risk.
• B. To speed up the climb regardless of safety.
• C. To allow the ladder to roll.
• D. To comply with paperwork.

Answer: (A)

Stability and fall prevention are the focus of proper ladder setup in exterior work. Setting the ladder at about a 75-degree angle places the ladder in a balanced position, roughly following a 4:1 base-to-height rule, so the weight and reaction forces keep the ladder from tipping or kicking out. Secure footing means the feet sit on firm, level ground and are stabilized—use levelers on uneven ground, anchor the base, or have a coworker hold the base—so the ladder doesn’t shift when you step on or lean. Outdoor surfaces can be slippery or soft, so ensuring a solid footing is essential to prevent slips and shifts as you move. When both angle and footing are addressed, the risk of falling is reduced and you can climb more safely. That’s why this option emphasizes stability and fall risk reduction.
