Objective

To understand the risks of overexertion and improper lifting, and to learn techniques for preventing injuries related to manual lifting and materials handling.

Introduction

Manual lifting and overexertion are significant causes of workplace injuries. Construction has one of the highest rates of back injuries of any industry. This toolbox talk will cover proper lifting techniques and ergonomic principles to minimize these risks. [1]

Hazard Identification

Identifying potential hazards associated with manual lifting is the first step in preventing injuries. Understanding these risks allows us to implement effective control measures.

• Lifting heavy objects: Back injuries, muscle strains, hernias, and disc damage. [1]
• Awkward postures and bending: Muscle strains, sprains, and long-term musculoskeletal disorders. [2]
• Twisting while lifting or carrying: Severe back injuries and spinal damage. [2]
• Repetitive lifting tasks: Cumulative trauma disorders, such as carpal tunnel syndrome and tendonitis. [3]
• Lifting objects that weigh over 50 pounds: Serious back injury [1]

Control Measures

• Use mechanical aids: Employ dollies, carts, forklifts, and other equipment to move heavy objects horizontally. Ensure workers are trained in the safe use of this equipment. [1]
• Plan lifts carefully: Clear the path, ensure good footing, and face the direction of travel before lifting. Warm up muscles before lifting. [1]
• Use proper lifting techniques: Keep your back as straight as possible, tuck in your chin, and lift with your leg muscles. Maintain a wide stance for balance and hold the load close to your body. [1]
• Team lifting: For objects over 50 pounds or awkward to handle, ask for assistance. Coordinate and practice team lifting techniques. [1]
• Minimize twisting: Avoid twisting your body while carrying an object. Turn your feet to change direction. [1]
• Adjust work area layouts: Reduce horizontal and vertical distances of lifting to lower handling demands. Ensure sufficient space for the entire body to turn and locate objects within easy reach. [2]

Personal Protective Equipment (PPE) Requirements

• Gloves: Wear gloves to improve grip and protect hands from cuts and abrasions. Anti-vibration wraps can lessen the shock of vibrating tools. [3]
• Footwear: Wear supportive footwear with good traction to prevent slips and falls. [4]
• Back support belts: While controversial, back support belts may provide some benefit for certain individuals during heavy lifting tasks. Ensure proper fit and usage.

Real-World Example or Case Study

Jeff, a masonry worker, moved 200 30-pound bags of concrete by hand in one day because he thought it would be faster than finding a cart. He damaged a disc in his lower back and could no longer do that kind of work. This could have been prevented by using a mechanical aid or asking for help. [1]

Group Discussion

Discuss the following questions:

1. Have you or someone you know ever had a back injury from lifting and carrying? If so, what happened?
2. How could the injury have been prevented?
3. What changes can we make to our work practices to reduce the risk of overexertion injuries?

Emergency Procedures

1. If an injury occurs, immediately stop work and assess the situation.
2. Provide first aid and seek medical attention if necessary.
3. Report the incident to the supervisor and complete an incident report.

Questions and Answers

• Q: What is the maximum weight one person should lift?

A: As a general guideline, never try to lift an item weighing over 50 pounds by yourself. Always seek assistance or use mechanical aids. [1]

• Q: What should I do if I start feeling pain while lifting?

A: Stop immediately and inform your supervisor. Continuing to work through the pain can lead to more serious injuries.

Summary

Recap of main points:

• Always use mechanical aids whenever possible to reduce manual lifting. [1]
• Plan your lifts, use proper techniques, and avoid twisting. [1]
• Ask for help with heavy or awkward objects. [1]
• Report any discomfort or pain immediately.

Report all hazards, near-misses, and incidents to your supervisor immediately.
