Fire Protection FAQs

What is Halon?

Halon is a fire suppressant agent found in both Fire Suppression Systems (Halon 1301) and Fire Extinguishers (Halon 1211). This is the most effective extinguishing agent available. Halon is a clean agent, which means it leaves no residue when used, so it causes no damage to your property. 

Is Halon Banned?

Halon is not banned, but it is no longer manufactured. The phase out is being discussed but no dates are set. For more information about the phase out you can read more information about the Clean Air Act on the US EPA’s website.


The use of Halon is not banned, but rather the manufacturing of Halon globally because of its Ozone Depleting properties. In 1987 the Montreal Protocol found that Halon was damaging the environment. In response to this, the U.S. created the Clean Air Act which was the legislation behind the ban.  

Who uses Halon?

Halon is still used in many applications. From protecting computer rooms throughout the electronics industry, to numerous military applications on ships and even on commercial aircraft, Halon is an integral and unparalleled fire-extinguishing agent. Halon 1211 fire extinguishers play a vital role in protecting peoples’ lives as well as property including homes, automobiles and boats.

How does Halon prevent a fire?/How does Halon work?

Contrary to popular belief, Halon does not remove oxygen from the air, but rather displaces the oxygen. When Halon is discharged on a fire, it breaks the chemical chain reaction. This accounts for most of its fire fighting properties the other properties come from the cooling effect of the expanding gas. Because of these properties, Halon can be used in an occupied space.

What is the HRC voluntary Code of Practice?

An ethical code of practice for reclaimers of Halon. This Code of Practice has been developed to assure the public that HRC Enrolled Sellers engaged in the business of Halon recycling and recovery, are operating in a manner that promotes safe and environmentally responsible Halon reclamation. View the HARC Code of Practice here.

What are laboratory certifications?

Laboratory Certifications are proof that an agent has been tested and has passed one of the industry-accepted standards (i.e. ISO-7201 or ASTM-D5632, Type 1 or Type 2). It is standard practice that every cylinder or bulk tank of agent that is supplied by A‑Gas has a laboratory certification.

What are "recycled halons" and where can I buy them?

Recycled Halons are used Halons cleaned by means of filtration, distillation, separation or other mechanical processes. As a result, our finished product meets the standards as set forth in ISO 7201 or ASTM D5632, Type 1 or Type 2. A‑Gas can assist sellers wishing to dispose of Halon in an environmentally friendly manner, and as well as buyers with “critical needs” who require Halon 1211 and 1301 for recharging their existing systems. A‑Gas operates a comprehensive Halocarbon Bank Management Program that meets all requirements of the EPA’s 1990 Clean Air Act as well as the HARC code of practice.


What is a Halocarbon Management Program?

A‑Gas established a comprehensive Halocarbon Management Program in response to our customer’s environmental and fire protection needs. We purchase, reclaim and sell recycled halocarbons, meeting or exceeding all industry standards. We only sell to “critical users” and strictly follow all regulations and laws regarding the safe handling and transportation of halogenated agents.

What if I need to dispose of my halon?

A-Gas can also help you dispose of your Halon. Occasionally, owners of ozone depleting chemicals may select destruction as a preferable option, especially if their corporate policies require permanent disposal of all ODS’s (Ozone Depleting Substances), Class 1 CFC’s and Halons. A-Gas stands ready to accept these unwanted agents for destruction. This program is located in Bowling Green, Ohio and can achieve destruction effiencies up to 99.9999%.

Can I buy used Halon?

No; when you buy a system container of Halon that has not been recycled and laboratory tested, you cannot be assured of what is in it. A-Gas takes great pride in selling only recycled and laboratory certified products. Always demand laboratory certifications for each tank or cylinder containing Halon. Visit NFPA for guidelines of refilling Halon.

What are clean agents and how are they used?

Clean agents are non-conductive, non-corrosive, and do not leave behind a residue. They are most often used in systems that protect irreplaceable or high value products such as data centers, museums, power plants, etc.


Can a Halon system still be recharged in the United States?

Yes, A-Gas still offers recharges and is available 24/7 for emergency recharges. We even have a strategic Halon reserve that gives us a consistent availability
