Final answer:
Everyone in the vicinity of power tools must wear safety glasses or goggles to protect against potential hazards from debris. Knowledge of safety equipment and guidelines is crucial for maintaining security in the environment where power tools are used.
Step-by-step explanation:
When power tools are in use, it is important for safety that everyone in the vicinity wears protective eyewear. This includes not only the person operating the power tool but also those nearby and observing. This is to ensure that any debris or particles that could be emitted from the power tools do not cause injury to the eyes. Safety glasses or goggles should be worn at all times to prevent accidents and protect against potential hazards.
Safety equipment, such as fire extinguishers and eyewash stations, should be known to everyone present in the laboratory or area where power tools are used. In addition, safety guidelines such as wearing gloves, safety aprons, and using a dust pan and broom to clean up broken glass must be strictly followed to maintain a safe working environment.
