The minimum tensile strength requirement for light use pulleys is 5 kN. This value is established based on the demands of various rescue operations where light-duty pulleys are employed. Light use pulleys are typically used in situations that do not involve extreme loads or conditions, such as in prompt rescue scenarios or during training exercises where the risk is moderate.

Using a pulley with a tensile strength of at least 5 kN ensures that the equipment can safely handle the forces typically encountered during light usage. Going below this minimum requirement could result in failure of the pulley during use, leading to compromised safety for the rescuers and victims involved.

It’s key to understand that while higher tensile strengths can be beneficial for other more demanding applications (like heavy lifting or industrial use), the specified minimum of 5 kN for light use pulleys balances effectiveness with practicality, ensuring that operators can perform their tasks safely without risking permanent damage to the equipment.
