Compliance overview
Scope and applicability
This standard specifies the requirements for personnel, equipment, systems, and procedures for air diving using compressed air as the breathing medium. It is applicable to air diving operations at depths shallower than 60 meters, as well as simulated diving exposed to compressed air pressures up to 0.6 MPa. This standard is mandatory for all commercial diving operations using compressed air within China.
Technical requirements
The standard outlines strict requirements for diving personnel, including training, qualification, and physical fitness, which must comply with GB 20827. It mandates specific roles such as diving supervisors, standby divers, and life support technicians to ensure operational safety. Comprehensive specifications are provided for equipment and systems, encompassing personal gear (masks, helmets, suits), hoses, umbilicals, gas supply systems, deck decompression chambers, control panels, and launch/recovery systems. All equipment must have identification numbers, maintenance procedures, and records. The standard details procedural requirements including risk assessment, emergency planning, and personnel allocation. It sets operational limits such as maximum diving depths, weather and current restrictions, and post-dive flying restrictions. Decompression procedures must follow GB 12521. Strict documentation and reporting protocols are required. This includes maintaining on-site safety manuals, emergency contact lists, and detailed diving logs for every operation, ensuring full traceability and accountability.
Testing methods
The standard outlines comprehensive on-site inspection and testing procedures for diving equipment and systems before operations. This includes visual inspections, pressure tests (pneumatic and hydrostatic) for hoses, gas supply systems, and deck decompression chambers, as well as performance tests for communication and electrical systems. Regular periodic verifications and calibrations of instruments and pressure vessels are strictly required.
