Welding and cutting may be done in mines if what condition is met?

Welding and cutting in mines are performed under stringent safety regulations to minimize risks associated with flammable materials and confined working environments. The correct answer emphasizes that all equipment and gauges must be maintained in safe condition. This is crucial because properly maintained equipment significantly reduces the likelihood of accidents caused by equipment failure or malfunction.

Safety regulations require that before any welding or cutting is initiated, checks must be performed to ensure that tools are functioning correctly and that safety features are operational. This maintenance helps ensure that gas cylinders, welding machines, and other related equipment are free from leaks and defects, thus safeguarding workers from potential hazards like fires or explosions, which can be particularly catastrophic in mining environments.

While other conditions, such as supervision, permitting specific operators, or designated hours, may contribute to a safer working environment, the fundamental need for maintaining equipment in a safe condition is paramount to making welding and cutting operations in mines viable and safe.
