Diver Underwater Operations Precautions: 1. Prior to entering the water for operations, divers should thoroughly inspect the performance of their diving equipment and ensure it is in perfect condition before donning and submerging.

2. Divers must not jump directly into the water. They should descend using the diving ladder and conduct a watertight check of the diving equipment and a performance check of the communication devices at the water surface. Upon passing the checks, they should descend along the guide line. If they experience discomfort during the descent due to pressure equalization, they should wait until symptoms subside before continuing. Upon reaching the work site, they should promptly notify the surface.

3. Divers should prevent falls when working at elevated underwater locations. Pay attention to obstacles during movement or work to avoid tearing the diving gear or damaging doors and windows. Underwater Construction Company

4. Divers must maintain air in their diving gear while underwater, ensuring that the upper body, above the hip bones, remains higher than the lower body, below the hip bones, to prevent the occurrence of air mixing and buoyancy accidents.

5. Divers should continuously monitor and clean the air supply hose and signal line during underwater operations to prevent entanglement or being pinched by objects.
