What should the diving supervisor ensure regarding the gas supply?

The diving supervisor plays a critical role in ensuring the safety of divers, and one of their responsibilities includes managing the gas supply effectively. Ensuring that the gas supply is activated before entering the water is essential for several reasons.

First and foremost, divers require a reliable and adequate gas supply to breathe while submerged. Activating the gas supply before entry allows divers to check their equipment and confirm that everything is functioning correctly. This precaution helps to avoid any potential problems once the divers are underwater, where addressing equipment issues would be much more complex and risky.

Additionally, by having the gas supply activated beforehand, the diving supervisor can ensure that divers are mentally prepared and not facing any last-minute equipment shortcomings that could affect their focus and performance during the dive. This proactive measure is a fundamental aspect of diving safety and helps to facilitate a smooth and safe diving operation.

Overall, having the gas supply activated before entering the water is a best practice that aligns with the principles of dive safety and operational readiness.
