Operating Instructions

WARNING

This manual is our effort to explain the operation, maintenance and use of the Kirby Morgan hel- met. We do not herein make any effort to teach the principles of diving. It is our assumption the reader is a qualified diver. We highly recommend that all divers should train, under controlled conditions, in the use of any model of commercial diving helmet that they have not previously used or trained in, prior to use on the job.

3.1 Introduction

This section provides advice on how to use your Kirby Morgan helmet. The use of these diving helmets will vary with the type of work and environmental condi- tions. The basic procedures of donning and removing these helmets will be similar for every job.

A proper training program in a calm, clear body of water should be undertaken. If the diver has not used a particular Kirby Morgan helmet before, he must not dive with the helmet without proper training.

However, divers that are familiar and trained in the use of previous Kirby Morgan masks; i.e., KMB 8, 9, 10, 18, 28, the Navy MK. 1 Mask, Navy MK. 21 helmet, or the Navy MK. 22 mask or the SuperLite helmets, will find that all Kirby Morgan diving hel- mets and masks have the breathing system controls located in the same position. The operation of this helmet will also be similar. The diver must be tended at the surface at all times by a trained, qualified com- mercial diving tender.

3.2 Design Purpose

All Kirby Morgan diving helmets are designed for use with an umbilical.

The umbilical is usually composed of at least a gas or air supply hose and communication wire, assembled with waterproof tape (and in some umbilicals wound similar to strands in a rope) to form a single unit. Some umbilicals also include a hose for hot water, a pneumofathometer hose, and a strength member, such as a cable or strong line.

It is strongly recommended that the air/gas umbilical be married to a strength member in a manner that allows the strength member to receive the strain. This will help reduce the possibility of umbilical and umbilical fitting fatigue and possible failure.

The umbilical is the diver’s lifeline to the diving control station.

WARNING

Kirby Morgan diving helmets are not in- tended for use with a self contained gas supply (scuba). There is no provision for surface swimming once the scuba air supply is depleted. This could lead to suffocation or drowning, which could be fatal.

The diver must be tended at the surface at all times by a trained, qualified commercial diving tender.
