What should divers do to ensure a successful gas switch during a cavern dive?

To ensure a successful gas switch during a cavern dive, it is essential to plan the switch in advance and ensure clear communication. This approach is fundamental because a gas switch is a critical procedure that can impact the safety of the dive. Prior planning allows divers to understand the specific conditions and timing for the switch, reducing the risk of errors under potentially challenging circumstances.

Clear communication among team members is vital both before and during the switch to ensure that everyone is aware of the plan and can react appropriately in case of an emergency. This helps in maintaining situational awareness and enhances safety in an environment where visibility and comfort may be limited.

By having a structured plan, divers can minimize risks associated with gas management and ensure that all team members are aligned in their actions. This preparation and communication help prevent confusion, ensure proper gas usage, and enhance the overall safety and success of the dive.
