Which of the following is NOT a method of protecting oneself while working with machinery?

Listening to loud music is not a method of protecting oneself while working with machinery. Safety in a manufacturing or industrial environment depends significantly on being aware of one’s surroundings and being able to hear potential hazards or warnings. Loud music can obstruct auditory cues, which are vital for maintaining safety.

In contrast, wearing safety glasses, keeping loose sleeves secured, and using guards on machines are all proactive safety measures designed to minimize risks. Safety glasses protect the eyes from debris and other hazards, securing loose clothing helps prevent entanglement in moving parts, and machine guards serve to physically block access to dangerous areas of machinery. Each of these actions contributes directly to worker safety and is crucial for maintaining a safe working environment.
