can be donned at anytime needed during emergency
egress. The hood protects the user from hazardous
environments, while allowing a full range of view. The
Teflon hood and breathing bag provide excellent heat
and chemical resistance. The compressed oxygen and
mouthpiece combination allows the Ocenco M-20.2
EEBD to be donned in a smoke-filled environment.
The actual EEBD can be identified by its orange
storage case. The training EEBD comes with two extra
mouthpieces and is stored in a light blue secondary
container. It provides training in both the worn and
stored positions.

Fire and Smoke Boundaries
Fire and smoke boundaries are determined for
each of the large engineering spaces aboard your ship.
The ship's fire doctrine lists both primary and
secondary boundaries. The boundaries are designed to
effectively contain a fire to prevent its spread.
Primary fire and smoke boundaries are set at all
bu l k h e a d s i m m e d i a t e l y a d j a c e n t t o t h e fi r e .
Boundarymen will man these primary boundaries with
a fire hose, and may have to cool the bulkhead to
prevent spread of the fire. Fire could spread through
any penetration, including ventilation, electrical
cableways, piping conduits, or defective welds in cases
of extreme heat.
A secondary set of boundaries is set at the next
immediate watertight bulkhead from the scene. If a
boundary fails, and the fire cannot be contained at the
first boundary, the boundaryman will attempt to secure
the space and evacuate. What were previously
