When working at underwater sites with differential pressure, what action is required?

When working at underwater sites with differential pressure, performing pre-dive planning and coordination is crucial. This action ensures that all divers are aware of the specific hazards and conditions they may encounter, such as strong currents, pressure differences that can create risks like entrapment, or sudden changes in buoyancy.

Effective pre-dive planning includes assessing the dive site, developing a dive plan that addresses safety protocols, setting up communication methods, and possibly rehearsing emergency procedures. This process is essential for maintaining safety because it prepares divers to act effectively in unforeseen circumstances and minimizes risks associated with differential pressures.

By engaging in thorough planning and coordination, divers can establish clear roles and responsibilities, ensuring everyone knows what to expect during the dive and how to respond to any emergencies that may arise. This collective knowledge and preparedness is fundamental to a safe diving operation at sites where differential pressure is present.
