To ensure the safe use of A-frame ladders and prevent falls and injuries, here are three critical safety precautions:

1. Proper Setup: Position the ladder on a stable, level surface. Ensure all feet are firmly planted and the ladder is fully opened with side locks engaged. Avoid using ladders on uneven ground without proper leveling using plywood or adjustable bases. A ladder that is not level will become unstable when a worker climbs it. [2] [3] [6]

2. Safe Climbing Practices: Always maintain three points of contact (two hands and one foot, or two feet and one hand) while climbing. Keep your body centered between the side rails and avoid overreaching. Never climb on the top step or the step below the topcap of a stepladder. Carry tools in a tool belt or hoist materials instead of carrying them while climbing. [1] [5] [1] [1]

3. Regular Inspection and Maintenance: Before each use, inspect the ladder for any signs of damage, such as cracks, loose rungs, or damaged feet. Ensure that all parts, including rung locks and spreader braces, are working correctly. If any defects are found, immediately tag the ladder as "DO NOT USE" and remove it from service for repair or disposal. [4] [7] [7] [7] [7]
