What is a requirement for hoist hooks during lifting operations?

During lifting operations, hoist hooks are required to have latches or be moused. This requirement is essential for safety, ensuring that the load remains securely attached to the hook during lifting. Latches help prevent accidental disengagement of the load, which could lead to dropping the load and causing injury or damage. Mousing refers to the practice of using wire or other material to secure the hook's latch closed, adding an additional layer of safety.

Using hooks without these safety features increases the risk of accidents during lifting activities. While color-coding, the condition of the hooks, and other features can contribute to safety and operational efficiency, they do not provide the same level of protection against unintentional load release as having latches or mousing does. Therefore, the requirement for latches or mousing is a fundamental safety measure in lifting operations, reinforcing the necessity of proper equipment standards.
