What is the primary responsibility of divers regarding safety while diving?

The primary responsibility of divers regarding safety while diving is to continuously monitor their air supply. This practice is essential because maintaining awareness of how much air is left is crucial for ensuring that divers can ascend safely and avoid potential life-threatening situations, such as running out of air while underwater. By regularly checking their air supply, divers can make informed decisions about their dive plan, including when to ascend and whether they need to share air with a buddy in case of an emergency.

Monitoring air supply not only helps divers manage their dive time effectively but also enhances situational awareness underwater, reducing the risk of panic and accidents. This responsibility aligns with the broader ethos of diving safety, which emphasizes personal accountability and proactive measures in maintaining one's own well-being while participating in the sport.
