Fires chloromethane

The principal PIC for penta and penta-treated wood would include volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), dioxins and furans, as well as SOj, COj, NO, and HCl. Penta would be expected to have undergone a very high destruction efficiency (DRE) during the fire (> 99.99%). Among the VOC emissions, the following chemicals likely contributed to air pollution problems benzene, bromobenzene, chloromethane, 1,3-butadiene, iodomethane, acetone, chloroform, and 1,2-dichloroethane. 

Contact with the following materials, containing combined hydrogen, is likely to cause fire or explosion acetic acid, ammonia, benzene, ethanol, hydrogen, hydrogen sulfide, methane cork, grease, paper, wax, etc. The carbon content further contributes to the observed reactivity [1]. Chloromethane reacts with explosive violence [2]. See Acetonitrile, above... 

The aerosol in its familiar modern form was first described in a patent filed in 1926 by Rotheim for the spraying of insecticides, paints, cosmetics, and fire extinguishants. Subsequent patents described a variety of propellants including chloromethane, hydrocarbons, such as 2-methylpropane, and dimethyl ether. The first successful introduction of aerosols on a large scale occurred in 1942 when a pyrcthroid/scsamc oil formulation pressurized with di-chlorodifluoromethanc (CFC 12) was developed by Goodhue and Sullivan for US military... 

CHLOROMETHANE (74-87-3) CH3CI Highly flammable gas [explosion limits in air (vol %) 8.1 to 17.2 flashpoint <32°F/<0°C autoignition temp 1170°F/632°C Fire Rating 4]. Moisture causes decomposition. Violent reaction with strong oxidizers, acetylene, anhydrous aluminum trichloride, ammonia, amines, ethylene, fluorine, interhalogens magnesium, potassium, powdered aluminum or zinc, sodium, and... 

OXYBIS (CHLOROMETHANE) (542-88-1) C2H4CI2O Highly flammable and water-reactive liquid. Forms explosive mixture with air (flash point <66°F/<19°C Fire Rating 3). Contact with acids or water causes decomposition, forming... 

Organohalogens are widely used in industry and society. Chloromethane is used as a solvent in rubber polymerization. Bromomethane is an important fumigant the related halons (CBrClF2 and CBrFj) are better fire extin-guishants than carbon dioxide.
