CO2 extinguishers

At least one CO2 extinguisher (10-B C) or equivalent other clean agent extinguisher should be located outside the entrance door to the unit electrical substation for Class C fires. 

All teaching and research laboratories are provided with a color-coded safety island, a highly visible, easily accessible area in which are located the emergency water sprayer, one or more CO2 extinguishers, a bucket of sand and a wall-mounted fire blanket. Dry powder extinguishers were avoided because of the destructive effect of the airborne powder on electronic instruments. 

Carbon Dioxide (CO ) extinguishers are used for Class B and C fires. CO2 extinguishers contain carbon dioxide, a non-flammable gas, and are highly pressurized. The pressure is so great that it is not uncommon for bits of dry ice to shoot out the nozzle. They don t work very well on Class A fires because they may not... 

ACETIC ACID, LEAD(II) SALT TRIHYDRATE (6080-56-4) Pb(C2H302)2 3H20 Contact with acids forms acetic acid. Incompatible with oxidizers, bases, acetic acid alkalis, aUcylene oxides, ammonia, amines, bromates, carbonates, citrates, chlorides, chloral hydrate cresols, epichlorohydrin, hydrozoic acid, isocyanates, methyl isocyanoacetate, phenols, phosphates, salicylic acid sodium salicylate, sodium peroxyborate, potassium bromate resorcinol, salicylic acid, strong oxidizers, sulfates, sulfites, taimin, tartrates, tinctures trinitrobenzoic acid, urea nitrate. On small fires, use dry chemical, Halori, or CO2 extinguishers. 

ACETILUM ACIDILATUM (50-78-2) C9Hg04 Combustible solid. An organic acid. Powder or dust forms explosive mixture with air (flash point 482°F/250°C). Reacts with strong oxidizers, strong acids, strong bases. Contact with alkali hydroxides or carbonates may cause decomposition. Incompatible with acetanilide, acetaminophen, some alcohols, aliphatic amines alkanolamines, alkylene oxides amidopyrine, amines, ammonia, caustics, epichlorohydrin, hexamine, iron salts isocyanates, phenozone, phenobarbital sodium potassium iodide quinine salts sodium iodide stearates. Slowly hydrolyzes in moist air. On small fires, use AFFF, alcohol-resistant foam, dry chemical powder, or CO2 extinguishers. 

Incompatible with strong acids, nitrates, oxidizers. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or CO2 extinguishers. 

F/>110°C). Hygroscopic. May form imstable and explosive peroxides. A possible polymerization hazard. Contact with strong oxidizers may cause fire and explosions. Contact with mixture of acetic acid + dinitrogen trioxide may cause explosion. Incompatible with strong bases, chlorinated hydrocarbons, nitro compoimds. On small fires, use foam, dry chemical, water spray, or CO2 extinguishers. 

ALLYL PHENYL ETHER (1746-13-0) C ipO Combustible liquid (flash point 143°F/62°C). May form peroxides on contact with air. Violent reaction may occur with strong oxidizers, strong acids acetyl peroxide boron trifluoride aluminum hydride (possible explosion). Incompatible with nitrosyl perchlorate, ozone (may form explosive ethyl peroxide, aldehyde and acetic acid). On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or CO2 extinguishers.
