Which precautions need to be taken when a halon fire extinguisher is used inside an aircraft cabin?

The extinguishing agent may decompose into poisonous components when heated; therefore the aircraft cabin must be ventilated well

Halon has a cooling effect. Once the fire has been extinguished, the source of the fire should not be cooled down further using non-flammable liquids

Halon suffocates the fire and additionally has a cooling effect. Aircraft occupants should be protected against the resulting cold and hypoxia

Halon fire extinguishers must be emptied in one single swell to avoid that the residual halon forms toxic components
