RADIOLOGICAL EMERGENCY RESPONSE PLAN IMPLEMENTING PROCEDURE V
EP-18 SAFETY-RELATED Fire Fighting
((Y, DATE /0 42/
/
APPROVED BY A.
PURPOSE This procedure describes the basic Fire Brigade organization and the various methods of fighting the different types of fires which can occur at Trojan. The methods described address "first aid" fire fighting functions in the event of a fire at the plant. This involves extinguishing small fires, containing large fires until offsite assistance arrives, assisting offsite fire fighting agencies, and performing rescue of personnel as necessary.
B.
PRECAUTIONS NOTE: This procedure assumes plant operators and security personnel have successfully completed the training program described in Administrative Order A0-9-5.
(j 1.
Observe the guidelines of EP-21, Reentry / Search and Rescue.
2.
The following precautions for fighting a fire at a nuclear power plant are required due to the additional hazards from radiation and radio-logical contamination (both surface and airborne) which may be present.
a.
Know the radiation levels in the #irefighting area from the general survey board, posted signs or ongoing surveys by Radiation Protection Technicians.
b.
Wear and periodically monitor personal dosimetry when entering radiation or high radiation areas to avoid exceeding exposure limits.
c.
Fires in surface contamination areas will probably also create an airborne contamination hazard; therefore, wear SCBA.
d.
Firefighters should not wear polyethelene boots or gloves since these may melt; turnout gear including rubber boots should provide adequate contamination protection.
A wide water fog pattern may help keep contamination from going e.
airborne or knock down airborne contamination present in smoke.
O)

(
)
f.
Smoke may be radioactive and ventilation should be performed via filters and an effluent monitor.
g.
Avoid directing high pressure water or dry chemical agent at areas or surface contamination as this may cause some of the contaminants to become airborne.
h.
RP personnel should monitor airborne contamination levels during the emergency and take action to reduce levels.
1.
Minimize excess water usage due to limited capacity of waste tanks and effluent discharge restrictions.
j.
Minimize unmonitored releases to the atmosphere of water or airborne contamination.
C.
AUTHORITY AND RESPONSIBILITY 1.

)
1.
When a small fire occurs that can be immediately and safely extinguished
\\,,
by those present, speed in extinguishing the fire should take precedence over reporting it; however, fires must be reported to the Control Room at the earliest opportunity. If more than one person is present, the fire should be reported immediately. (Typically, a small fire is one that can be readily extinguished with one hand-held portable extinguisher.)
2.
Any person discovering a fire will:
a.
Broadcast the alarm over the plant; paging system.
Fire, fire, fire in (location)." Repeat announcement.
l l
b.
Notify the Control Operator directly (Extension 251, 252 or 256) giving the location of the fire. (Plant locations will be described by a noun name vice zone location.)
3.
The Control Operator will, upon notification of a fire:

2)
Reignition of gas if one of the legs of the fire triangle is not removed.
c.
Strategy on Fighting Flammable Gas Fires.
1)
Protect surrounding equipment, usually by providing a fog pattern to cool the equipment.
2)
Shut off the source of the leakage prior to extinguishment.
This reduces the potential for explosion.
3)
Extinguish the remaining fire, usually with water or_ dry chemical-type agent.
d.
Sources of 011 Fires.
1)
Lube oil storage and leaks.
2)
Hydraulic oil storage and leaks.

G 5)
Transformers (combination of Class C and Class B).
6)
Computer room fires.
b.
Strategy of Extinguishment.
1)
Deenergize the equipment if possible.
2)
Use Halon or cabon dioxide if possible to minimize the residue and cleanup time.
3)
Ensure the agent penetrates into the motor or cabinet via l
vents, etc.
Otherwise, the fire may reflash.
4)
If water must be used, use only a fog pattern and stand no closer than six (6) feet from the energized 30 KV (or less) electrical source..
5.
Suppression of Electrical Cable Fires a.
Cable Fire Suppression Strategy:
1)
Use self-contained breathing apparatus due to toxic products of combustion.
EP-18 Page 7 of 9 Revision 2 I
L
t b (s_,
2)
Attempt to deenergiz6 the source of electrical current.
3)
A life line may be needed due to the density of the smoke.
4)
Use carbon dioxide or dry chemical extinguishers if practicable, since they are relatively nonconductive.
5)
Water may be used and is recommended on large cable fires, but recognize the hazard and use only a fog nozzle no closer than six (6) feet.
b.
Smoke control is very important to minimize damage to electrical equipment.
1)
Use installed smoke exhaust systems in the Cable Spreading Room, Control Building ESF Switchgear Room and Turbine Building ESF Switch Gear Room.
2)
Portable smoke exhaust fans may be used in other areas for smoke removal.
CAUTION: Smoke in radiologically controlled areas should be monitored an filtered prior to discharge.
c.
Safety factors to be considered when using water on electrical fires:
k 1)
Use a wide fog pattern; never use a solid stream..
s i
2)
The return current is reduced as the distance from the source is increased. Remain six (6) feet or more from equipment energized to 30 kV or less. This will reduce current to the nozzle.
a 3)
Reducing vcitage reduces current; therefore, deenergize the cable or equipment if possible.
1 4)
All electrical equipment shall be considred energized if any question exists as to its condition.
6.
M miting Fire Damage:
a.
Use fans for smoke removal.
b.
Choose the proper extinguishing agent.

j f.
Use water properly to minimize water damage.
g.
Dry chemical agents may be corrosive to stainless steel and electrical equipment. It should be cleaned expeditiously and the components examined to determine extent of damage.
7.
Fire in Radioactive Area A fire in a radioactive area requires observing the precautions as d
listed at the start of this procedure. Additioually, the following steps shall be taken af ter the fire has been extinguished:
a.
Monitor Personnel for Contamination.
i 1)
External.
2)
Internal monitoring may also be required.
'i b.
Monitor fire fighting and emergency equipment for contamination under the direction of Radiation Protection personnel.
c.
Determine radiation exposure of fire fighting personnel. A Radiation Work Permit' may also need to be prepared to document exposures.
j d.-
Areas in or adjacent to the fire area may require decontamination.
e.
An environmental monitoring program for areas surrounding the
~ plant may be required if contamination has spread outside the l
controlled area.
f.
Smoke damage to electrical equipment and stainless steel piping i.
must be assessed due to the high chlorine content of the polyethlene i
used for contamination control.
)
g.
Dry chemical agent used in areas of stainless steel piping or l
machinery must be thoroughly cleaned and then inspected.
[
8.
Fire in Safety-Related Areas Fire in these areas are treated as a fire in any other area. The specific problems are the effects of smoke, water, or fire damage on the safety-related equipment. These areas should be thoroughly 3
inspected before energizing the equipment. The keys to the entrances
~
should be brought to the scene by the Fire Brigade Leader.
