To lift safely, size up the load and make sure you can lift it. Plan the move. Ask yourself how far do you have to carry the load and is there a safe place to put it? Make sure you have firm footing and a path clear of tripping hazards.
Bend your knees and get a good grip on the object. Keep your back natural by maintaining those natural curves. Lift with your legs. Keep the load close. Hug your work. Know your limitation and ask for help if it is needed. Pick up the object smoothly-no jerking.
Remember, to prevent back problems, avoid fatigue, get a good night's sleep, and don't over-lift. Maintain a good posture by keeping the natural curves. Establish an exercise program. Eat a balanced diet and know good work habits.
