                 Pentafluoroethane is a refrigerant that has zero ozone depletion potential.It has the formula CF3CHF2. Although it has zero ozone depletion potential, it has high global warming potential, reported by the United States Environmental Protection Agency (EPA) as 3450 times that of carbon dioxide.[1]

Pentafluoroethane in an zeotropic mixture with difluoromethane is known as R-410A, a common replacement for various chlorofluorocarbons (commonly known as Freon) in new refrigerant systems. Pentafluoroethane is also used as a fire suppression agent in fire suppression systems.

                 HFC-125 (ECARO-25 / FE-25 / NAF S 125) can be used in clean agent fire suppression systems also referred to as Gaseous fire suppression Agent. It is generally used in situations where water from a fire sprinkler would damage expensive equipment or where water-based fire protection is impractical, such as museums, banks, clean rooms and hospitals . HFC-125 does not deplete ozone (ODP 0) The HFC-125 clean agent is stored in a pressurized container and introduced into the hazard as a gas. The agent is odorless, colorless, electrically non-conductive, non-corrosive, and leaves no residue. It is used in occupied enclosed areas that contain high-value assets.

                  HFC-125 suppresses fire by absorbing heat energy at its molecular level faster than the heat can be generated, so the fire cannot sustain itself. It also forms free radicals to chemically interfere with the chain reaction of the combustion process. This makes it a highly effective fire fighting agent that is safe for people and causes no damage to equipment.

                  The HFC-125 fire suppression agent is a non-ozone depleting replacement for Halon 1301. In addition,HFC-125 leaves no residue on valuable equipment after discharge.

                  HFC-125 is considered a Clean Agent and is therefore included in the National Fire Protection Association's 2001 - Standard for Clean Agent Fire Extinguishing Systems.

                  When introduced to the market HFC-125 was not considered safe for use in occupied spaces. The US EPA Significant New Alternative Policy (SNAP) listing reflected this. Following the introduction and acceptance of the PBPK model in the NFPA standard 2001 on Clean Agent Fire Extinguishing Systems 2004 Edition, the restriction was relaxed and now HFC-125 can be used in occupied hazards. Generally, class B (flammable liquid) hazards require concentrations that exceed the agent's no observable adverse effect level (NOAEL) so extra precautions must be taken to avoid prolonged exposure to the agent.
