Final Answer:
In maintenance operations involving flammable liquids, flammable gases, and explosives, the use of intrinsically safe electrical equipment is a required electrical safety measure.
Step-by-step explanation:
When dealing with flammable materials such as liquids, gases, or explosives in maintenance operations, the risk of fire or explosion is heightened. To mitigate this risk, one essential electrical safety measure is the use of intrinsically safe electrical equipment. Intrinsically safe devices are designed to prevent the release of electrical energy that could potentially ignite flammable substances in the surrounding environment. These devices are constructed and certified to operate safely in hazardous locations, minimizing the risk of sparks or overheating that could lead to a fire or explosion.
Intrinsically safe equipment plays a crucial role in ensuring the safety of personnel and facilities during maintenance operations involving flammable substances, contributing to the prevention of accidents and the
