The potential hazards of working with machinery include electrical shock, entanglement, and noise.

Electrical shock is a serious hazard associated with machinery that operates on electricity. If proper safety procedures are not followed, workers may inadvertently come into contact with live electrical components, leading to severe injuries or even fatalities.

Entanglement refers to the risk of clothing, hair, or body parts getting caught in moving machinery parts. This can result in severe injuries or accidents if safeguards, such as guards or protective equipment, are not used properly.

Noise is another prevalent concern in environments where machinery is used. Prolonged exposure to high noise levels can lead to hearing loss and increase the risk of accidents, as it may interfere with communication and the ability to hear warning signals.

While skin irritation, fire hazards, respiratory issues, falling objects, chemical exposure, and heat are all valid hazards in certain contexts, the options presented in the other choices do not encompass the specific and direct dangers typically associated with machinery operation as effectively as the correct choice.
