The diving contractor must ensure that the dive team is provided with all the necessary equipment and procedures to undertake the diving work without undue compromise to health and safety. The choice of equipment location will be determined by the type of diving work, the detail of the type of diving equipment involved, the integrity of any handling system with respect to lifting points or load bearing welds, and structures etc. In this respect it should be ensured that in-date test certificates for all relevant equipment are available.

In some applications the diving system may be required to operate in a hazardous area (for example: an area in which there is the possibility of danger of fire or explosion from the ignition of gas, vapour or volatile liquid). All diving equipment used in such an area must comply with the safety requirements for that area.
