I don't think that was a Li-On battery though as the crew member extinguished it by throwing water over it.
Hey Kelvin,
are you crew? Check your company's regs!
Flighting Lithium fires should be ready knowledge for at least flight crew, and as a matter of fact for anyone who carries a laptop, iPad or whatever which has a lithium battery.
From
IATA.org:
A lithium battery fire should not be treated as a Class D fire. Fighting a fire that contains lithium batteries requires:
1. Removing external electrical power from device (if applicable) 2. Extinguishing the fire, and
3. Cooling of the remaining cells to stop the thermal runway.
Halon or Halon replacement and/or water fire extinguishers can be used to control the fire and prevent its spread to surrounding flammable materials. This should be followed by immediate dousing with water or other non-flammable liquid from any available source to douse the fire. Monitor for re-occurrence and continue to pour non-flammable liquids to cool cells until cooled.
Examples of non-flammable liquids: water, juice, coffee, tea, etc.
