|  Radiological Safety Training for Plutonium Facilities
DOEHDBK11452001
Student's Guide
B. Abnormal conditions could include the following:
Fires/explosions
Natural disasters
Plutonium releases
Failure of systems (e.g., ventilation)
Other hazards
C. Fire safety
Because of the inhalation hazard, fires in
plutonium facilities require particular care.
It is important to distinguish between fires
that threaten to involve plutonium and those in
which the plutonium is burning. For plutonium
metal, complete exclusion of oxygen and/or
rapid heat removal are the only truly effective
means to extinguish fires. Due to reactivity and
criticality concerns, water may not be the
appropriate extinguishing agent for a fire, as it
acts as a moderator and may lead to criticality.
Fire systems are therefore tailored to the facility
situation.
Good housekeeping is more than keeping
things picked up and in their assigned place to
reduce tripping hazards and present a pleasant
work environment and a better appearance to
inspectors. Consideration must also be given to
combustible loading and the storage and use of
combustible and flammable materials. The
quantity of chemicals and all materials should
be minimized, as these contribute to fire
initiation, reactions, fire intensity, waste
production, and spread of contamination.
