If you lift or move anything, follow these tips to lift safely:

• How far will you have to carry the load?
• Is the way clear of clutter, cords, slippery areas, overhangs, stairs, curbs, or uneven surfaces?
• Are there handles or places on the load to hold it easily? Is it a standard shape or is it irregularly shaped? If it’s an irregular shape, can you put it in a box or bin that is easier to carry?
• Will there be doors that are closed?
• Once you pick up the load, will you be able to see over it?
• Can the load be disassembled, carried in pieces, then reassembled?
• Can you lift and move this by yourself? Do you need help? Can you use a cart or hand truck?
• Are there tools/devices available to help, and do you know how to use them?

• If you are doing a two-person lift, communicate when you lift, move and place the load!
• Start the lift by putting your feet close to the object. Get a firm footing.
• Center your body over your feet.
• Avoid lifting over your head, if possible.
• Squat down like a professional weightlifter, bending your knees. Keep your back straight or slightly arched. Your legs should do the lifting, not your back!

• Keep the load as close to you as possible.
• Keep the load between your shoulders and knees, your “Power Zone”.
• Use your feet to change directions, never twist your back.
• Keep your head up and look straight ahead, not down.
• Keep your back straight or slightly arched.
• Beware of stairs, obstacles and uneven floors!
• When using a cart, push rather than pull. Secure the load to the cart

• Opposite of lifting the load
• Position yourself where you want to set the load.
• Squat down. Let your legs to do the work, not your back.
• Do not twist your body while setting down a load, and keep your head up.
• Once the load is where you want it, release your grip. Do not release your grip on a load until it is secure.
• If someone is helping you, coordinate putting the load down.
