2.1.1 As far as reasonable and practicable, a
diving system should be designed to minimize human error and constructed
so that the failure of any single component (determined, if necessary,
by an appropriate risk assessment) should not lead to a dangerous
situation.
2.1.2 Diving systems and components thereof should
be designed for the conditions under which they are certificated to
operate.
2.1.3 Materials for diving system components should
be suitable for their intended use.
2.1.4 All components in a diving system should
be designed, constructed and tested in accordance with international
or national standardsfootnote recognized by the Administration
or proprietary specifications acceptable to the Administration.
2.1.5 In the design of pressure vessels including
accessories such as doors, hinges, closing mechanisms and penetrators,
the effects of rough handling and accidents should be considered in
addition to design parameters such as pressure, temperature, vibration,
operating and environmental conditions.
2.1.6 All components in a diving system should
be so designed, constructed and arranged as to permit easy cleaning,
disinfection, inspection and maintenance.
2.1.7 A diving system should include the control
equipment necessary for safe performance of diving operations.
