Back Safety: Preventing the Most Common Workplace Injury
Jul 31st 2018
Back injuries are the most frequently reported workplace injury. Injuries to the back can cause debilitating pain and permanently impact one’s quality of life. While some back injuries are the result of a fall, impact, or other trauma, most can be prevented through proper posture and body mechanics. This guide will help you understand proper techniques for lifting and moving items in the workplace.

HOW DOES THE BACK WORK?
Some of the most common mistakes workers make when lifting or moving heavy items are twisting, bending, overexertion, and lifting with poor posture. To understand how to lift and move objects properly, it is helpful to know how the back works.
The main structural element of your back is the spinal column, made up of 33 vertebrae connected by facet joints. Spinal discs cushion movement with a tough outer layer and a softer inner core. The spinal cord passes through openings in the vertebrae, sending information between the brain and body.
Because the back is essential to performing everyday tasks, injuries can be extremely disruptive and painful.
Common Back Injuries
Strains
Strains occur when muscle fibers or tendons are stretched or torn.
- Grade I: Mild stretching, painful but not weak.
- Grade II: More fibers are stretched, causing swelling and reduced strength.
- Grade III: Complete muscle tear with significant pain and loss of strength.
Sprains
Sprains are ligament injuries caused by stretching or tearing.
- Grade I: Painful stretch.
- Grade II: Partial tear with swelling and limited movement.
- Grade III: Complete tear with severe pain and instability.
Muscle Spasms
Involuntary contractions often caused by overuse, dehydration, or fatigue.
Damaged Discs
Bulging or ruptured discs can cause pain, numbness, and nerve pressure.
BACK INJURY RISK FACTORS
Back injuries are the most common type of workplace injuries. Everyday work tasks often involve bending, lifting, twisting, or reaching, and without proper technique, strain can accumulate over time.
- Poor posture
- Twisting or bending
- Overexertion
- Insufficient rest time
Personal health factors such as obesity, smoking, weak muscles, and poor nutrition can increase injury risk.
PROPER LIFTING TECHNIQUES
Posture
Maintaining the natural “S” curve of the spine prevents pressure on the discs and muscles.
- Ears aligned over shoulders
- Arms below shoulders
- Feet flat and shoulder-width apart
- Forearms relaxed and neutral
Avoid slouching and take frequent position-changing breaks.
Body Mechanics
Use your legs — not your back — when lifting.
- Avoid twisting or bending at the waist
- Keep objects close to your torso
- Use mechanical aids or team lifting for heavy loads
Avoid Excessive Repetition
Muscles need recovery time. Break up repetitive tasks and use ergonomic tools when possible.
Avoid Excessive Force
Never exceed 50 pounds when lifting alone. Use tools or coworker assistance.
LIFTING AND MOVING TECHNIQUE
Before lifting, plan your route, clear pathways, and determine load weight.
- Know the weight of the load
- Choose lifting method (solo, team, machine)
- Clear hazards from the path
Steps for a Proper Lift
- Stand close with feet shoulder-width apart
- Bend knees into a squat position
- Keep the load close to your torso
- Tighten your abdomen
- Lift using leg muscles
Awkward or Uneven Loads
Keep the heavier side closest to your body. Use kneeling techniques for very low loads. Use a stool or ladder for items above shoulder height.
Carrying Loads
Maintain straight posture, look ahead, and avoid twisting. Use mechanical aids for heavy or bulky items.
GENERAL PREVENTION
Exercise, nutrition, and healthy habits play a critical role in preventing back injuries.
Exercise: Strengthens muscles and reduces injury risk.
Healthy Weight: Reduces strain on back and knees.
No Smoking: Smoking accelerates spinal disc damage.
CONCLUSION
Back injuries are the most common workplace injury, but proper training, posture, lifting techniques, and healthy lifestyle choices significantly reduce the risks. Safe lifting training should be ongoing, reinforced frequently, and supported by proper equipment and workplace ergonomics.
