What is the minimum duration for torch use according to safety procedures?

Having a minimum duration for torch use is vital in safety procedures, especially in situations where visibility may be compromised, such as during emergencies or in low-light environments. The correct answer, which states 30 minutes, reflects a standard time that ensures the torch can provide sufficient light for safety tasks, inspections, or emergency operations.

This 30-minute duration is designed to accommodate necessary tasks, allowing crew members to effectively maintain safety protocols, check equipment, or navigate safely when light sources may be limited. It recognizes the need for a reliable light source that is readily available during critical periods, thus supporting overall crew safety and operational integrity.

In practice, a duration of 15 minutes may not provide enough time for certain safety assessments, while longer durations such as 2 or 4 hours might be excessive, potentially leading to issues like battery exhaustion if not properly managed. The emphasis on a practical and realistic time frame—30 minutes—aligns well with the operational needs of crew members in various scenarios.
