EMERGENCY RESPONSE
– 14 –
Fire
Approach and extinguish a fire using proper vehicle fire
fighting practices.
• Extinguishing Agent
Water has been proven to be a suitable extinguishing agent.
•
Initial Fire Attack
Perform a fast, aggressive fire attack.
Divert the runoff from entering watershed areas.
Attack teams may not be able to identify a RX400h until the
fire has been knocked down and overhaul operations
have commenced.
•
Fire in the HV Battery Pack
Should a fire occur in the NiMH HV battery pack, attack crews
should utilise a water stream or fog pattern to extinguish
any fire within the luggage compartment
except for the
HV battery pack.
When allowed to burn themselves out, the RX400h NiMH battery
modules burn rapidly and can quickly be reduced to ashes except
for the metal.
Offensive Fire Attack
Normally flooding the NiMH HV battery pack with copious
amounts of water at a safe distance will effectively control the HV
battery pack fire by cooling the adjacent NiMH battery modules
to a point below their ignition temperature. The remaining
modules on fire, if not extinguished by the water, will burn
themselves out.
However, flooding the RX400h HV battery pack is not
recommended due to battery design and forward location
preventing the responder from properly applying water through
the available vent openings safely. It is recommended that the
incident commander allow the RX400h HV battery pack to burn
itself out.
WARNING:
• Potassium hydroxide and sodium hydroxide are key ingredients in the
NiMH battery module electrolyte.
• The modules are contained within a metal case and access is limited to
duct openings under the rear seat.
• The HV battery cover should never be breached or removed under any
circumstances including fire.
• Failure to follow these warnings can cause severe burns and electric shock
that may result in death or serious injury.
