The emergency procedures listed are primarily intended as the diver’s first response to a situation or event that could be life threatening if swift immediate action is not taken. All emergency procedures assume that the helmet is being dived with two independent breathing supplies to the diver umbilical so that one is in use, and one is in standby. In addition it is also assumed that the helmet is being used with a fully functional emergency gas supply that is lined up to the side block so that only the side bock emergency valve needs to be opened to supply gas to the side block. Surface supply systems must be capable of delivering the required pressure and volume to satisfy the diver respiratory requirements. All users of KMDSI Helmets and Full-Face masks should be professionally trained in the helmets use, set-up, adjustment procedures, as well as all applicable user level maintenance. All persons involved in the diving operations should memorize the emergency procedures and protocol. All topside support personnel should be trained and qualified to perform the duties for which they are being employed. These emergency procedures list only what the diver should do. Each organization / company should develop policy, emergency, and operational procedures in accordance with (IAW) governing regulations and / or industry standards and consensus and the guidelines given by the manufacturer of the equipment.
The guidelines that dictate when or how a diver should abort a dive must be established by the organization /company. These guidelines need to be based on governing regulations, industry and consensus guidelines. In some cases, the diver may be the one making the decision to abort and in other cases, (i.e. deep air, mixed gas, decompression obligation) the decision might be made by the topside supervisor. Regardless, all users must have a plan and protocol, and all members of the dive team must know the plan and protocol. The overall responsibility rests with the Diving Supervisor.
