Avenger 227© is an effective fire extinguishing agent that can be used on many types of fires ranging from sensitive electrical equipment to industrial applications using flammable liquids. Avenger 227© is ideal for applications where clean-up of other medium presents a problem, where an electrically nonconductive medium is needed and where people compatibility is an overriding factor. When environmental impact becomes a consideration, Avenger 227© is particularly useful. It has Zero ozone-depleting potential, low global warming potential, and short atmospheric lifetime. These characteristics make it suitable not only for new installations using an Avenger total-flooding system, but also for Halon 1301 replacement applications. Avenger 227© is an odorless, colorless, liquefied compressed gas. It is stored as a liquid and discharged into the hazard as a colorless, electrically non-conductive vapor that is clear and does not obscure physical vision. It leaves no residue and has acceptable toxicity for use in occupied spaces at design concentration. Avenger 227© extinguishes a fire by a combination of chemical and physical mechanisms. Avenger 227© does not displace oxygen and therefore is safe for use in occupied spaces without fear of oxygen deprivation.
