Answer :
James Cameron completes pressure testing and emergency evacuation drills to ensure safety inside his sub. These drills test the sub's ability to withstand high pressure and prepare the crew for safe evacuation in an emergency. The correct answer is 1.
The two drills that James Cameron completes to ensure safety inside his submersible are pressure testing and emergency evacuation drills. Pressure testing is crucial to ensure that the sub can withstand the extreme pressures of the ocean depths.
This involves simulating the sub's exposure to high-pressure environments to ensure its structural integrity. Emergency evacuation drills prepare the crew for the potential need to exit the sub quickly and safely in case of an emergency. These drills typically involve practicing the use of escape equipment and procedures.
Training like that experienced by the U.S. Navy divers at the Naval Diving and Salvage Training Center often includes additional protocols such as training in a recompression chamber, hyperbaric oxygen therapy, and understanding the risks associated with pressurized gases in the body to prevent diving-related injuries. The correct answer is 1.
