Wear welding masks and goggles, gloves, and leather aprons when welding. If working with chemicals, wear the protective equipment specified by the label. Use ladders properly. Firmly place the ladder on the ground with a distance away from the wall no more than 1 foot for every 4 feet of height. Do not use metal ladders near power lines or other areas that may cause electrical shock.
Lift objects correctly.
Lifting subjects the back to its greatest stress. Train your workers to lift properly. Keep the back straight while using the legs to lift the object. If heavy objects are to be lifted, provide back supports for workers. Better yet use mechanical lifting devices.
