The code is an especially vital document for contractors and clients working in unregulated areas of the world; and it has been instrumental in improving diving safety.  While national regulations take precedence over the code, it is a strong and recognised source of good practice.  This code provides advice on ways in which diving operations can be carried out safely and efficiently.  It outlines minimum requirements, creating a safe ‘level playing field’ for all diving contractors.  It also recommends how clients and contractors may analyse the safety implications of commercial requirements.

The code is regularly updated to reflect developments in good practice and technology. It incorporates both the substantial experience and expertise of our members as well as reference to other IMCA guidance.

IMCA has also prepared appendices for countries and regions with their own specific regulations or requirements:

• Gulf of Mexico appendix
• Middle East appendix
