Portable ladders are a simple and effective means for safe climbing except for one major problem. Workers sometimes find portable ladders so easy to use that they neglect normal precautions and safety rules. The result, too often, is an accident.
A ladder should always be examined before it is used to be sure there are no defects that make it unsafe to use. (The reason a ladder should never be painted is that the paint could conceal significant defects.)
A ladder is unsafe to use if side rails are cracked or split or if there are sharp edges or splinters on cleats, rungs, or side rails. Check also for missing, broken, or weakened cleats, rungs, or treads by placing the ladder flat on the ground and walking on it. If a defective ladder cannot be repaired, it should be disposed of permanently.
Once the ladder has been checked and found safe, set it at an angle of about 75° with the floor or ground. The distance from the wall to the foot of the ladder should be about equal to 1/4 of the ladder’s total length.
After setting the ladder in place, check it for firm and level footing. To prevent slipping, nonslip points or safety shoes are recommended. But, if this is not practical, the ladder should be secured firmly by lashing it with rope or some other suitable line.
The ordinary straight ladder is not built to support more than one person at a time. In going up or down, always face the ladder and grasp the side rails with both hands.
Never carry tools or materials in your hands when going up or down the ladder. Instead, put them in a sack that hangs from a strap over your shoulder or use a bucket and rope to raise and lower them.
Don’t lean a ladder against an object that might move, and never lean it against a window sash. If you must work near or on a window, fasten a board securely across the top of the ladder to give a bearing on each side of the window
Always stay below the top three rungs unless you have a firm handhold or a safety belt. Even then, you should hold on with one hand while working.
Be sure you keep moving the ladder as needed to reach new areas to be worked. Never overreach, push, or pull the ladder while working on it. Never straddle the space between the ladder and another object or try to work in a high wind. Any of these actions could upset you and the ladder.
If you’re working in front of a door that opens toward the ladder, the door must be blocked open, locked, or guarded. In any other situation in which a person or vehicle may bump into the ladder, get a helper to stand guard. If you can’t, then be sure to rope off the space around the ladder.
Ladders can be a great help on the job. They’re simple to use and get you where you need to be. Although ladders are uncomplicated devices, they can be dangerous. It’s important to know and follow ladder safety guidelines.
