What is the duration of the Portable Halon Fire Extinguisher?

• A. 5-7 seconds
• B. 20-30 seconds
• C. 10-12 seconds
• D. 1 minute

Answer: (C)

Discharge duration is how long the extinguisher releases its agent after you push the handle. For a portable Halon extinguisher on an E-190, that release lasts about 10–12 seconds. This reflects the amount of Halon in a standard aircraft portable unit and the flow rate through the nozzle. The short, intense burst is meant to knock down a small fire quickly by covering the base of the flames with a sweeping motion, then you reassess or take further action if the fire isn’t out. The other time options don’t match the typical capacity and flow of a standard aircraft portable Halon extinguisher.
