According to OSHA regulations, how many randomly broken wires are permissible in a 6x19 IWRC RRL hoist line?

The correct answer indicates that under OSHA regulations, a maximum of five randomly broken wires is permissible in a 6x19 Independent Wire Rope Core (IWRC) Rotation Resistant (RRL) hoist line. Understanding this limit is crucial for maintaining safety and ensuring the integrity of the wire rope used in lifting operations.

Wire ropes are engineered with specific tolerances, and the health of the rope is critical to prevent failures during lifting tasks. The IWRC design allows for improved strength and stability, making it suitable for challenging lifting environments. When inspecting a hoist line, a count of broken wires helps operators assess the condition of the rope. If the number of broken wires exceeds this limit, it signals that the rope may be at risk of catastrophic failure, necessitating immediate replacement to ensure the safety of personnel and equipment.

Knowing this permissible limit helps operators and maintenance personnel make informed decisions about the usability of the hoist line and reinforces the importance of regular inspections and adherence to safety regulations.
