Firefighting
HFC's in fire protection are : HFC's at extinguishing concentrations are safe and can therefore be used in normally occupied spaces. They are used at well below toxic levels HFC systems require ... system lifetime the installed HFC can be easily recovered and recycled. Economic aspects Since HFCs are much more effective extinguishing agents compared to inert gases or CO2 , HFC systems need 4 - 7 ...

Other Greenhouse gases - HFCs
Unfortunately, though they provide an effective alternative to CFCs, they can also be powerful greenhouse gases with long atmospheric lifetimes. The three main HFCs are HFC-23, HFC-134a and HFC152a, with HFC ... widely used refrigerant. Since 1990, when it was almost undetectable, concentrations of HFC-134a have risen massively. HFC-134a has an atmospheric lifetime of about 14 years and its ...
