'We advise that when employing a diver for the first time, contractors should look carefully at certificates and logbooks as forgeries have often been found to be of poor quality. References should be followed up or contact made with previous employers. Certificates should be checked against other photo ID such as a passport. Contractors should run a check against lists of invalidated certificates. And, if they are in any doubt, contractors should contact the issuing body (information note IMCA D 06/05 sets out contact details for HSE and all IMCA-recognised bodies).'

The IMCA is also aware of a number of falsified experienced diver competence assessment certificates in circulation. These fraudulent certificates have been based upon those accepted under IMCA’s information note D 26/01. Checks on certificates issued by national authorities can be made as described in IMCA’s information note D 16/07 and checks on experienced diver competence assessment can be made through the issuing organisation.

The IMCA can help members identify the appropriate body for verifying diving certificates and fraudulent certification should be reported. Members can call +44 (0)20 7824 5520; fax an enquiry to +44 (0)20 7824 5521 or email an enquiry to info@imca-int.com. The IMCA warns that divers using falsified qualifications are not only a danger to themselves, but to all around them.
