What is required for the safe attachment of electrical equipment in mining operations?

The requirement for proper fittings to prevent disconnection is crucial for the safe attachment of electrical equipment in mining operations. In such hazardous environments, electrical safety is paramount to prevent accidents such as equipment failures or short circuits that could lead to fires or electrocution. Proper fittings ensure that electrical connections are secure and resilient against the physical stresses common in mining, where vibrations, movements, and environmental factors could otherwise compromise the integrity of the connections. This minimizes the risk of accidental disconnection or exposure of live wires, thus protecting the safety of personnel and ensuring the reliability of the equipment.

While durable materials and inspections are important for overall safety and maintenance, the specific aspect of preventing disconnections directly addresses the immediate dangers associated with electrical equipment in mining operations. It ensures that equipment remains operational and does not pose a hazard to workers, which is why it stands out as the correct response in this context.
