Extension Ladder Safety
Extension Ladder Safety

4 to 1 Ratio

Place an extension ladder at a 75-1/2° angle. The set-back ("S") needs to be 1 ft. for each 4 ft. of length ("L") to the upper support point.

Safety Do's

Climb facing the ladder. Center your body between the rails. Maintain a firm grip

Always move one step at a time, firmly setting one foot before moving the other

Haul materials up on a line rather than carry them up an extension ladder

Use extra caution when carrying anything on a ladder

Safety Dont's

DON'T place the base of an extension ladder too close to the building as it may tip over backward

DON'T place the base of an extension ladder too far away from the building, as it may slip out at the bottom. Set the ladder at a 75-1/2º angle

DON'T over-reach, lean to one side, or try to move a ladder while on it. You could lose your balance or tip the ladder. Climb down and then reposition the ladder closer to your work!
