EPA Snap List
The Significant New Alternatives Policy (SNAP) Program is U.S. EPA's program to evaluate and regulate substitutes for the ozone-depleting chemicals that are being phased out under the stratospheric ozone protection provisions of the Clean Air Act (CAA). As per Section 612(c) of the Clean Air Act, the Agency is authorized to identify and publish lists of acceptable and unacceptable substitutes for class I or class II ozone-depleting substances.

The purpose of the program is to allow a safe, smooth transition away from ozone-depleting compounds by identifying substitutes that offer lower overall risks to human health and the environment.

The SNAP program has reviewed substitutes for the many industrial sectors, including Fire Suppression and Explosion Protection and it covers the following end-uses:

• Total Flooding Agents are where a specific concentration of extinguishing agent is achieved in an enclosed area by discharge of an automatic system. SNAP has approved alternatives for Halon 1301, including NAF S 125®, NAF S 227® and NAF S III® Fire Extinguishing Agent. The latter was the first product worldwide included in the SNAP List as an acceptable substitute for Halon 1301.
• Streaming Applications are where an extinguishing agent is directed to a fire using portable fire extinguishers. SNAP has approved streaming agent alternatives for Halon 1211, including NAF P IV® Fire Extinguishing Agent.

U.S. EPA also maintains a list of Halon Substitute Manufacturers that includes Safety Hi-Tech.
