When should a worker stop using a tool?

A worker should stop using a tool if they notice any signs of damage or malfunction because continuing to use a damaged or malfunctioning tool can lead to accidents, injuries, or further damage. Tools that are not functioning properly may pose serious safety risks, as they could fail to operate as intended, potentially causing harm to the user or those nearby. It is critical for workers to regularly inspect their tools and equipment before and during use to ensure they are in safe working condition. Recognizing issues early and ceasing use not only prioritizes personal safety but also maintains a safe working environment for all involved.

The other situations listed do not necessarily warrant an immediate cessation of tool use. Feeling tired or the absence of a supervisor may suggest that a worker should take precautions or be more cautious, but they do not in themselves indicate that a tool is unsafe to use. Stopping work at the end of a shift is a routine practice but unrelated to the condition of the tools being used.
