Purpose.

The purpose of this doctrine is to identify equipment, systems, and procedures used to prevent, control, extinguish and overhaul* a Class BRAVO fire in a machinery space*. Words used for the first time which are defined in the glossary, are marked with an asterisk (*). This doctrine covers the preferred sequence of events during a major oil leak or machinery space fire. Reference (d) provides additional guidance on fighting shipboard fires. Where conflicts arise between this doctrine and References (b), (c), (d) and (e), this doctrine takes precedence. This doctrine does not replace use of good judgment by all hands. All hands must be familiar with all firefighting systems and equipment available to them and the best to use for different fires. When a fire starts, it is too late to read this doctrine.
