For safety, two people are required to lift anything weighing more than how many pounds?

• A. 10
• B. 30
• C. 40
• D. 20

Answer: (C)

Two-person lifting is recommended when the load is heavy enough to threaten safe posture and spine health for a single lifter. In many safety guidelines used in veterinary and clinical settings, 40 pounds is the practical threshold: above this weight, maintaining a neutral spine, stable grip, and proper leg-driven lift becomes more difficult for one person, increasing the risk of back strain and injuries. By sharing the load with a partner, you can divide the weight, keep the load close to the body, and coordinate movements to avoid twisting or jerking.

To lift safely, assess the load first and plan the lift with your partner. Use good form: feet shoulder-width apart, hinge at the hips and bend the knees, keep the back straight, hold the object close to your center of gravity, and coordinate your lift. If the object is awkward, bulky, or slippery, or if you’re unsure about the weight, use a cart, dolly, or another mechanical aid.
