FACT SHEET: LISTING OF SUBSTITUTES FOR OZONE-DEPLETING SUBSTANCES UNDER THE SIGNIFICANT NEW ALTERNATIVES POLICY (SNAP) PROGRAM: UPDATE TO THE LIST OF ACCEPTABLE SUBSTITUTES IN FIRE PROTECTION
1. What does this direct final rule do?
This rulemaking lists three substitutes as acceptable, subject to use restrictions, for ozone-depleting halons in the fire suppression and explosion protection sector. Two of the substitutes are for use as total flooding agents to replace halon 1301, and one substitute is for use as a streaming agent to replace halon 1211. The listing is as follows:
- Powdered Aerosol F (KSA): acceptable subject to use conditions as a substitute for halon 1301 in total flooding uses—for use only in normally unoccupied areas;
- Powdered Aerosol G (Dry Sprinkler Powdered Aerosol (DSPA) Fixed Generators): acceptable subject to use conditions as a substitute for halon 1301 in total flooding uses—for use only in normally unoccupied areas; and
- C7 Fluoroketone: acceptable subject to narrowed use limits as a substitute halon 1211 for streaming applications—for use only in non-residential applications.
2. Who will be affected by this decision?
This listing provides users of specialized fire protection systems with additional flexibility in choosing alternatives to ozone-depleting halons. The primary users for these fire suppressants are specialty industrial and commercial fire protection applications.
