Fire Emergency Handling
Batteries on fire may release flammable and toxic gases and cause insulation
failures. During the fire extinguishing process, all emergency response personnel
must wear a full set of protective suite, including flame retardant or fireproof
clothing, air-purifying respirator or breathing apparatus, fire helmet, and insulated
shoes.
A battery fire may reignite after having been extinguished. After the fire is
extinguished, cool the batteries for at least 24 hours and observe them using a
thermal imager to ensure that the batteries decrease to room temperature.
Issue 04 (2023-11-10)
The ventilation and exhaust system must interact with the fire alarm system
and limit the concentration of flammable gas to below 25% of the lower
flammability limit (LFL).
Shall be equipped with fire extinguishers filled with halogenatedane or
perfluorohexanone, which shall interwork with the fire alarm system. After
the extinguishing agent is released, the battery room shall meet the
requirement on flame extinguishing concentration within 10 min.
Shall be equipped with dry-type water fire extinguishing facilities such as a
water spray or sprinkler system. Ensure that the water stored can be supplied
for more than 2 hours at the designed water flow rate and that the
surrounding water source shall be able to supply water continuously for 12
hours to cope with the risk of reignition or fire spreading after a battery fire is
extinguished.
Shall be equipped with explosion relief devices or pressure relief channels
(such as glass windows and magnetic lock doors) with equivalent areas.
According to the NFPA 68 or GB 50016 standard, if side pressure relief is
adopted, a protective fence or wall shall be installed outside the pressure
relief channels, and the fence or wall shall be at least 12 m away from the
pressure relief wall. Explosion relief doors and windows must not be opened
towards the emergency exit.
Firewater drainage facilities shall be installed. Firewater shall be collected in a
designated containment area or directed to the firewater treatment system
located on the campus.
Shall provide coordinated control for fire protection to disconnect the power
supply not intended for fire protection in the area on fire and related areas. It
is recommended that the power supply be disconnected before the automatic
sprinkler system is triggered.
Fire alarms shall be automatically reported to the fire supervision center. If
the battery room is unattended, an automatic fire alarm system shall be
deployed to report fire alarm signals to the remote management center.
Other requirements specified in applicable standards (such as NFPA 855,
NEN-1010, and GB 50016) shall also be met.
