Answer:
Lifting heavy objects incorrectly can put undue stress on the lower back and cause serious back injury and pain.
The National Library of Medicine says that the most common cause of acute back pain is a sudden injury to the muscles and ligaments supporting your back. Lifting heavy objects can cause muscle spasms, strains and tears to the muscles and ligaments that lead to significant back pain. Rest, gentle exercise and over-the-counter pain medications help relieve back pain associated with heavy lifting, but you may require professional orthopedic care in some cases.
Lifting heavy objects correctly can reduce your risk for painful spasms, strains and tears.
Lifting Heavy Objects Correctly
Examine the object for potential problems
Look for holes, tears, rips, dangling pieces or contents that may shift as you lift the object. Determine if the object is slippery or difficult to grasp.
Assess the weight of the object
Push the object lightly with your hands or feet to see how easily it moves. Remember – a small package is not always lightweight.
If it weighs more than you can safely lift by yourself, do not attempt it. Break down the object into smaller pieces and make several trips, if possible, or ask someone to help you.
Think through the task before you begin
Decide ahead of time where you will put the object and how you will get it there. Map out a safe route and remove any obstacles that may trip you. Beware of puddles, uneven floors and unsecured rugs that may slip out from under you. Determine if you will need a ladder, dolly, hand truck, gloves or other special equipment.
