SafetyQuestion 88 of 100
What is a key requirement when setting up an extension ladder against a wall?
a.Lean it as steeply as possible
b.Place the base right at the wall
c.Set it at roughly a 4-to-1 ratio (base one foot out for every four feet of height) and secure it against slipping
d.Rest it on a stack of paint cans for height
Explanation
A stable extension ladder is positioned so the base is about one foot away from the wall for every four feet of working height, giving roughly a 75-degree angle. It should be on firm, level ground and secured against slipping, extending above the landing when used for access. This reduces the risk of the ladder kicking out or tipping.
