How often should emergency drills be conducted according to NORAC?

The correct answer emphasizes the importance of regularly conducting emergency drills as outlined in the guidelines provided by NORAC. This systematic approach ensures that all crew members are familiar with emergency procedures, which is vital for maintaining safety and preparedness in the event of an emergency. Regular drills help reinforce training, allow for the assessment of response times, and enable the identification of any gaps in knowledge or procedures among the crew. Additionally, these drills should be tailored to account for various scenarios that may occur, thereby enhancing the overall effectiveness of the preparedness strategy.

Other options suggest a more limited frequency of drills. For example, conducting them only once a year would not allow for adequate practice or retention of crucial emergency procedures, as skills may fade over time without regular reinforcement. Similarly, limiting drills to situations involving new crew members does not take into account the ongoing training needs of existing crew members who also must remain proficient in their emergency response skills. The suggestion of conducting drills whenever deemed unnecessary contradicts the very nature of safety and preparedness, as regular practice is essential regardless of perceived necessity.
