CS 25J1197 Fire extinguishing agents

(a)Fire extinguishing agents must:

(1)Be capable of extinguishing flames emanating from any burning of fluids or other combustible materials in the area protected by the fire extinguishing system; and

(2)Have thermal stability over the temperature range likely to be experienced in the compartment in which they are stored.

(b)If any toxic extinguishing agent is used, provisions must be made to prevent harmful concentrations of fluid or fluid vapours (from leakage during normal operation of the aeroplane or as a result of discharging the fire extinguisher on the ground or in flight) from entering any personnel compartment, even though a defect may exist in the extinguishing system.
