Full body harness selection principle and wearing method

Full-body harnesses are essential personal protective equipment (PPE) designed for fall protection, especially for workers at height. Their primary function is to prevent falls from elevated positions or to safely suspend the worker in case of a fall, ensuring their safety and reducing the risk of injury. A full-body harness distributes the force of a fall across the body, minimizing the chance of serious harm. The anchorage point must be capable of withstanding a static load of over 15 kN for at least three minutes, as required by standards such as GB6095-2009, EN361, and EN358. Among all types of fall protection systems, the full-body harness is the only one that provides comprehensive body support.

Choosing the right seat belt depends on the nature of the work and the working environment.

Option 1: Suggested configurations based on the environment:

• Scaffolding: Single-point harness, shock-absorbing lanyard, or double-lanyard
• Roof and maintenance work: Three-point full-body harness, double-fork energy absorber, horizontal lifeline, and man-riding arrestor
• General factory areas: Standard hanging-point harness, personal fall arrester
• Power line work: Full-body harness with positioning lanyard, sling, shock-absorbing lanyard, fall arrester, and double-fork energy absorber

Option 2: Main types of full-body harnesses:

1. Single-point harness: The most widely used type, suitable for most fall protection scenarios. The rear D-ring is the recommended attachment point.
2. Double-point (three-point) harness: Ideal for tasks involving vertical movement, such as climbing up and down. It offers enhanced stability and comfort.
3. Belt-equipped harness: Also known as a five-point harness, it provides both positioning and fall protection, making it ideal for complex or high-risk environments.

Option 3: How to properly wear a full-body harness:

1. Hold the D-ring on the back of the harness and shake the unit to ensure all straps are properly aligned. Inspect all components for damage and check the size label to confirm it fits correctly.
2. If any straps or buckles are not open, untie the webbing or release the buckle to adjust the fit.
3. Place the shoulder straps over your shoulders, ensuring the D-ring is centered between your shoulder blades.
4. Loop the leg straps between your legs. Hold the back leg strap with one hand and pull it forward through the armpit to the other hand, securing it with the front buckle. Repeat for the second leg strap. If there’s a waist belt, fasten it securely.
5. Adjust the chest strap so it sits in the middle of your chest. Tighten the straps, and tuck any excess webbing into the clips to prevent it from loosening during use.
6. Once all straps are fastened, tighten the buckles so the harness fits snugly against your body without restricting movement. Ensure all parts are secure and ready for use.

Proper use and regular inspection of full-body harnesses are crucial to maintaining safety in high-risk environments. Always follow manufacturer guidelines and industry standards when selecting and using fall protection equipment.
