Ladder Set-up

Self-Supporting Ladder Set-up Requirements

• Place the base of the ladder on a firm and level surface. Ensure that all four feet are on the ground. Use leg levelers on uneven surfaces.
• Open and lock the spreader bars.

Non-Self-Supporting Ladder Set-up Requirements

• Place the base of the ladder on a firm and level surface. Make sure that both feet are on the ground. Use leg levelers on uneven surfaces.
• Use the 4:1 rule to achieve the required angle. For every 4 feet up, place the base of the ladder 1 foot from the wall or support surface that it rests against. To check that the ladder is set up at a 4:1 angle, stand in front of the ladder with your toes at the ladder's base and extend your arms straight out. Your fingertips should touch the rung nearest to your shoulder level if the ladder is set up at a proper 4:1 angle.
• Place the ladder against a solid, stable surface. Ensure that both side rails are equally supported.
• If you will be stepping off the ladder onto an access point, the ladder's rails must extend at least 3 feet above the access landing, and you must tie off or otherwise secure the ladder's side rails at the top.
• When you use an extension ladder, make sure that the rung locks are engaged, and make sure that the minimum required overlap between sections is maintained.
