Which of the following is a requirement for electrical equipment used in mines?

The requirement for electrical equipment used in mines is that it must be examined weekly. Regular weekly examinations ensure that any potential hazards or issues with the equipment can be identified and addressed promptly, thereby maintaining safety standards in the mining environment.

Weekly examinations are crucial because they allow for the detection of wear, damage, or any operational issues that may develop over time due to the harsh mining conditions. This proactive approach is essential in preventing accidents and ensuring the reliability of the equipment, protecting both workers and infrastructure.

While daily inspections are important for general operational safety, the regulation specifically mandates a weekly examination to ensure compliance with safety standards. The other options suggest examination intervals that either do not meet regulatory requirements or are not practical given the conditions and the frequent use of electrical equipment in mining operations.
