Caution

2.3 Emergency situation
Despite of its careful and professional protection design against any hazard
results, damage of the battery may still occur. If a small amount of battery
electrolyte is released due to a serious damage of the outer casing; or if the
battery explodes due to not being treated timely after a fire breaks out nearby,
and leaks out poisonous gases such as carbon monoxide, carbon dioxide etc.,
the following actions are recommended:
1) Eye contact: Rinse eyes with a large amount of running water and seek
medical advice
2) Contact with skin: Wash the contacted area with soap thoroughly and
seek medical advice
3) Inhalation: If you feel discomfort, dizziness or vomiting, seek medical
advice immediately.
4) Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to extinguish
the fire if there is a fire in the area where the battery pack is installed.
Wear a gas mask and avoid inhaling toxic gases and harmful substances
produced by the fire.
5) Use an ABC fire extinguisher, if the fire is not caused by battery and not
spread to it yet.
Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design
against any hazard results, rupture of battery shall still occur due to
mechanical damage, internal pressure etc., and may result in a leakage of
battery electrolyte. The electrolyte is corrosive and flammable. When there is
fire, the toxic gases produced will cause skin and eyes irritation, and
discomfort after inhalation. Therefore:
1) Do not open damaged batteries.
2) Do not damage the battery again (shock, fall, trample, etc.).
3) Keep damaged batteries away from water (except to prevent an energy
storage system from catching fire).
Warning!
If a fire has just occurred, try to disconnect the battery circuit breaker an
d
cut off the power supply first, but only if you can do so without endangeri
ng
yourself.
If the battery is on fire, do not attempt to extinguish the fire and evacuate
the crowd immediately.

4) Do not expose the damaged battery to the sun to prevent internal heating
of the battery.
Electrical hazard: The reason of fire and explosion accidents in lithium
batteries is battery explosion. Here are the main factors of battery explosion:
1) Short circuit of battery. Short circuit will generate high heat inside battery,
resulting in partial electrolyte gasification, which will stretch the battery
shell. The temperature reaching ignition point of internal material will lead
to explosive combustion.
2) Overcharge of battery. Overcharge of battery may precipitate lithium
metal. If the shell is broken, it will come into direct contact with the air,
resulting in combustion. The electrolyte will be ignited at the same time,
resulting in strong flame, rapid expansion of gas and explosion.
