What is the minimum air requirement for a standby diver for dives deeper than 60 fsw?

The minimum air requirement for a standby diver for dives deeper than 60 feet sea water (fsw) is established to ensure the safety and readiness of the diver in emergency situations. A standby diver is positioned to assist the primary diver and must always be adequately equipped with enough air supply to respond effectively if a rescue is necessary.

In accordance with the Navy Dive Manual and safety protocols, a minimum of 100 standard cubic feet (SCF) of air is required for standby divers at depths exceeding 60 fsw. This amount ensures that the standby diver has sufficient air for a safe ascent and any required interventions, such as providing assistance or executing a rescue if needed.

By specifying a minimum level of air, the guidance ensures that the standby diver can maintain not only their own safety but also facilitate the safety of others involved in the diving operation. This requirement is crucial in maintaining a high standard of readiness and safety in underwater operations.
