WARNING
Do not perform this test unless the
diver and his tender are stationed im-
mediately adjacent to the diver’s air
manifold and you are certain the air
is on to the manifold. If the diver is
unable to flow air to the helmet, either
through the umbilical or the bailout,
he may not be able to remove the hel-
met easily.
To break the seal in this situation, the
diver must put his hand between the
neck dam and the neck, and pull the
neck dam away from the neck. A ten-
der must be standing by to assist the
diver in removing the helmet if need-
ed. Suffocation could result.
Turn the supply gas off at the dive control system

To perform this test, the diver must have an assistant
standing by. The assistant should be in control of the
gas supply console in the event the diver needs air or
Although the diver must be capable of donning and removing the helmet himself, the tender must ensure that the helmet is
properly secured on the diver.
