Re: ~At The Indian Barbershop~
R-290 and R-600A are used in some air conditioning systems and they are Propane and Iso-Butane respectively. Obviously both are very flammable, so they are only used in new, modern equipment designed specifically for them, to mitigate the hazard of a flammable refrigerant. They are also considerably cheaper than HCFC's and HFC's, so it's possible that some unscrupulous HVAC may have used it to charge an older piece of AC equipment. IIRC because it has to be very pure, there are no mercaptans added to the gas, so there is no smell with a leak |

Re: ~At The Indian Barbershop~
The way that hairdresser lit up after the initial ignition, I'm assuming he must have been poofed up something fierce with hairspray or flammable oils in his hair or ignitable body lotions or something. People just don't ignite like that unless they're covered in some kind of accelerant  |

Re: ~At The Indian Barbershop~
Not sure if you are just inexperienced in HVAC or purposefully misleading here. You seem to be at the very least confusing refrigerants and air conditioning systems. Flammable refrigerants are NOT used in HVAC as the volume of refrigerant is far too great. The only devices using flammable refrigerants are small, self contained units like ice makers and small form factor refrigerators, etc. While all the devices spoken about here use, "refrigerants" they are only related in the fundamentals of how cooling is achieved. If this and the other Indian commercial building explosive fire were caused by filing an HVAC unit with a flammable gas, it was NOT by accident, and this occurance PAINFULLY HIGHLIGHTS why flammable refrigerants are NOT used... |
