In fire extinguishers the main components are CO2 and may be water depending on the kind of objects on fire.So chloroflourocarbons are not needed.But in hairsprays the perfume is made from certain fragrances whose chemical natures vary from spray to spray(i.e it may be made from flowers or laboratory prepared substances.Chloroflourocarbons maybe added to preserve the biologocal and degradable components of the hairspray.It may also be added to volatalize the spray when in use.
Yes. There are over 400,000 reported car fires each year. Are you prepared if it happens to you? You can be with an auto fire extinguisher. Effective on oil, grease, gasoline and electrical fires, auto fire extinguishers feature simple, easy-to-read instructions for quick reference as well as a mountable safety bracket. Look in the automotive department of any box type store or your local auto parts store for a fire extinguisher specifically labeled for use in an auto. They generally are rated class B for flammable liquid and class C for electrical fires.
