I would like to replace an extinguisher in an ATR42.
There is a Water Extinguisher, certified for Class A fire, and a Halon Extinguisher, certified for Class B and C fire.
My customer wants to have two Halon Extinguisher, certified for Class B and C fire.
The JAR25.851 says that :
We must have at least 2 extinguishers (it's ok), and at least 1 Halon Extinguisher. The other Extinguisher may be choosen in accordance with kind of fires likely to occur where used.
· Class A: Fires involving ordinary combustible materials, such as wood, cloth, paper, rubber and plastics;
· Class B: Fires involving flammable liquids, petroleum oils, greases, tars, oil base paints, lacquers, solvents, alcohols and flammable gases;
· Class C: Fires involving energised electrical equipment where the use of an extinguishing agent that is electrically nonconductive is important.
As the extinguisher if for passenger cabin, I think a Class A is required for luggages.
Has someone already met this kind of problem ?
Is a Class A extinguisher mandatory ?
