Halon used as an extinguishing agent is forbidden as per:
- Montreal and Kyoto protocol
- ICAO statement
From 2025, all portable fire extinguishers on in-service aircraft must be replaced by halon-free equipment.
You can replace all cockpit and cabin portable fire extinguishers by HAFEX bottles. HAFEX is the lightest alternative to existing halon extinguishers and weighs only 2.4kg per bottle (including 1.6kg of 2BTP agent and a bracket).
