    Abstract - (Show below) - (Hide below)

    Specifies requirements for the design, construction, operation and maintenance of hyperbaric oxygen facilities. Includes equipment requirements, guidance on hazard identification, risk assessment and control and personnel requirements. Appendices include a suggested maintenance schedule, medical examination details, and training for hyperbaric attendants, chamber operators and hyperbaric technical officers.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements and recommendations for the design, construction, operation and maintenance of pressure vessels used for human occupancy other than those used in conjunction with, and support of, underwater diving operations.Minimum training requirements for hyperbaric attendants, chamber operators and technical officers are included in appendices.NOTES: 1 Both monoplace and multiplace hyperbaric chambers are covered.2 This Standard does not address hypobaric chambers.3 Facilities such as sporting domes and medical or industrial clean rooms which operate at very low increased pressures are excluded from the scope of this Standard.
