Step ladder injuries are among the most common and most preventable on NYC construction sites. Workers climb above the safe climbing position, stand on top of the ladder to gain extra height, use a closed step ladder as a leaning ladder, or set up on uneven ground. These are not failures of equipment — they are failures of habit, and they cause serious falls every year in New York City.

• Never stand on the top cap or the top two steps of a step ladder — these steps are not engineered for standing load and provide no handhold
• Fully open the ladder and lock both spreader bars before use — a step ladder that isn't fully open is unstable and will fold under load
• Never use a step ladder in the folded (closed) position as a leaning ladder — the side rails are designed for compressive load, not lateral bending
• Never climb from one side to the other over the top — dismount and reposition

• All four feet must contact the floor surface — on uneven ground, level with adjustable feet or a solid base pad. Never shim with scrap lumber or wedges
• Face the ladder when climbing and descending — never climb with your back to the ladder
• Keep body centered between the rails — never lean to either side beyond the rail
• Do not use a step ladder near a door unless the door is locked, blocked open, and posted with a warning
