PDF copy of Course notes for the Divator Mask and Breathing Valve, short service course for Dive technicians.

An invaluable reminder on key points- especially those involved with mixed gas diving- and guidance on maintaining oxygen service equipment.

These notes are recommended only for experienced technicians, who have attended one our service courses. Candidates for the CT1 course are issued with a copy.

CT1: Training for Divator Mask technicians

Course Aims

The course incudes safety considerations for compressed diving gases and how this should govern workshop safety and maintenance considerations.

Aimed at promoting ability and precision in servicing the DIVATOR range of POSITIVE and AMBIENT pressure operational demand valves, this module does not replace the full, three-day, DIVATOR service course (which includes service and maintenance to the High pressure and Reserve air modules of the Divator). The course achieves technical competence in stripping the mask and demand valve components. It includes simple methods of hose inspection and signs of worn supply hose but it does not equip the technician to pressure test or tensile test supply hoses to the requirements of EN250.

Consistent with the manufacturer’s service instructions, warranties and guidance, the course will enable the successful candidate to confidently repair field-serviceable parts of the world’s best mask and demand valve system and to test demand valves dynamically, as required in the service manual, checking operational pressure ranges and ensuring compliance with minimum flow rates.

The service work required presumes availability of compressed air supplies, meeting breathing air standards, at a pressure between 8 and 10 barG. - and a supply able to provide excess of 5 litres/second FAD at a dynamic pressure of 6 bar.

Course time: Six hours teaching and two hours practical and theoretical examination. This includes break times, which include group discussion and questions

Certificates of Proficiency are sent to the technician’s employer as evidence of compliance and competence under the UK Diving regulations, the CoSHH and PPE regulations

Results and auditing: The course scope limits the service course Certificate validity to three years, after which time a refresher course is required, to ensure proper updating, changes to standards and so forth.
