Which gaseous extinguishing system is no longer in production?

Gaseous extinguishing systems come in several flavors, each with its own environmental and health considerations. The key point here is regulatory action aimed at protecting the ozone layer and reducing environmental impact. Halons use halogenated compounds that are extremely effective at stopping fires, but they have high ozone depletion potential. Because of that, production of Halons was phased out under international agreements like the Montreal Protocol, with only limited exemptions for existing stock and legacy systems. In practice, this means Halon production has ceased, and these systems are being replaced with modern clean agents or inert gas options. Other options—such as clean agent systems (a broad category that includes newer substitutes), inert gas systems like Inergen, and CO2 systems—are still produced and used, though they come with their own safety considerations and application limits. So Halon is the one no longer in production.
