Halotron - Clean Fire Extinguishing Agent Replacement for Halon 1211

Halotron is a clean fire extinguishing agent intended to replace Halon 1211 in streaming applications. NFPA 2001, "Standard on Clean Agent Fire Extinguishing Systems" defines a "Clean Agent" to be "electrically non-conducting, volatile, or gaseous fire extinguishant that does not leave a residue upon evaporation." Halotron is a safe, effective, environmentally acceptable replacement for Halon 1211. It is discharged as a liquid that rapidly evaporates. Halotron is a proprietary three component chemical blend based on HCFC-123.

Halotron Approvals

U.S. Environmental Protection Agency (EPA)
"Significant New Alternatives Policy" (SNAP) Program
The EPA's SNAP program is a requirement under Section 612 of the Clean Air Act Amendments of 1990. The EPA's objective is to evaluate alternative chemicals and processes intended to replace ozone depleting substances like CFCs and Halon to ensure that they are acceptable from a human health and environmental perspectives. Proposed alternatives must have an acceptable environmental impact, have low toxicity and must be relatively clean or volatile. The replacements must also be commercially available and effective fire suppression agents.

Under the CAA, Halons are considered "Class I" in which production was stopped on January 1, 1994. HCFCs like Halotron are considered transitional "Class II" substances.

In the final SNAP rule, published in the Federal Register on March 18, 1994, Halotron was listed as a "Class II" substance acceptable streaming agent substitute for Halon 1211 in commercial/industrial, maritime, and military uses. New production of Halotron is subject to a complete phase-out in the year 2030.
