Preventing Tether Hook Failure

Understanding the Risk
The safety harness tether is a vital piece of personal protective equipment (PPE) designed to safeguard individuals working at height or in hazardous environments. However, even the most robust tether can be compromised if not used correctly or maintained properly. One critical factor that can significantly reduce the strength of a tether is lateral loading on the tether hook.

Lateral loading occurs when the force applied to the hook is not directly in line with the tether's axis. This can happen when the hook becomes entangled with deck fittings, equipment, or other obstructions. When subjected to lateral forces, the hook can deform or even fail, leading to a catastrophic loss of the tether's integrity and potentially putting the wearer at risk of serious injury or death.

The Importance of Proper Anchoring
To prevent the strength of a safety harness tether from becoming compromised due to lateral loading, the method used to anchor the end of the tether to the vessel must be carefully considered. The primary objective is to ensure that the tether hook cannot become entangled with any deck fittings or other equipment.

Avoid Obstructions:
Clear the Path: Route the tether and hook away from any potential obstructions, such as cleats, winches, or other equipment that could cause entanglement.
Use Protective Covers: If obstructions cannot be avoided, consider using protective covers or sleeves to minimize the risk of the hook snagging.
Regular Inspection and Maintenance:
Inspect the Tether and Hook: Regularly check the tether for signs of wear, damage, or deterioration. Pay close attention to the hook for any signs of deformation or bending.
Replace Damaged Equipment: If any damage is found, replace the affected component immediately. Do not attempt to repair damaged equipment.
Proper Tether Attachment:
Secure the Hook: Ensure that the hook is securely clipped to the anchor point, with no slack in the tether.
Avoid Twisting: Prevent twisting of the tether, as this can weaken the fibers and reduce the overall strength.

Additional Safety Tips:
Training and Education: All personnel who use safety harnesses should receive proper training on their correct use, inspection, and maintenance.
Emergency Procedures: Develop and implement emergency procedures for rescuing individuals who may become incapacitated while using a safety harness.
Regular Safety Audits: Conduct regular safety audits to identify potential hazards and ensure compliance with safety regulations.
By following these guidelines and prioritizing safety, you can significantly reduce the risk of tether hook failure and protect yourself and your crew from potential harm. Remember, a strong and reliable safety harness tether is an essential component of a comprehensive safety program.


Good guys.
