accessories. Test rope and pulley. Be sure all bolts and rivets are in place and secure. Make sure ladder is free of foreign material.

Clear clutter from area.
Block off area so people or equipment won’t interfere.
If close to a corner or near a door, use a guard and/or proper signage.

SETTING UP A LADDER(Extension Ladder)
75.5 from the horizontal is optimum resistance to sliding, ladder strength, and balance (angle of inclination).
One-Quarter Rule - One foot away from wall or object for each four feet of ladder’s length.
Place feet against object and “walk” ladder up; then position.
12
SETTING UP A LADDER(Self-Supporting Ladder)
