What should personnel do if they encounter a failure in laser safety equipment?

Personnel should report any failure in laser safety equipment immediately and cease using the equipment to prevent potential hazards. This action is crucial because the safety of personnel and others in the vicinity is of utmost importance when dealing with lasers, which can pose serious risks such as eye injury or skin damage.

By stopping usage and reporting the issue, personnel ensure that the equipment can be assessed, repaired, or replaced by qualified technicians knowledgeable in laser safety protocols. This creates a safer working environment and helps maintain compliance with safety regulations and standards.

The other options undermine safety procedures; using faulty equipment compromises safety, attempting repairs without proper training could lead to further issues, and waiting to inform a supervisor dismisses the urgency of the situation.
