Final answer:
A student should seek clearance from the Safety Officer before entering a tank or void to ensure all safety protocols are followed and the environment is safe for entry.
Step-by-step explanation:
Before entering a tank or void, it is essential to have clearance from the Safety Officer. The Safety Officer is responsible for ensuring that all safety protocols are followed and that the environment is safe for entry. They assess risks, monitor conditions, and provide the necessary permits or denial for entry. Commanding Officers, Hull Maintenance Technicians, and Damage Control Assistants may have roles in overall safety and operations, but the specific task of clearing an individual for entry into a potentially hazardous environment like a tank or void falls under the purview of the Safety Officer.
