Fire extinguisher ranges

Sodium Bicarbonate. Many soda ash plants convert a portion of their production to sodium bicarbonate [144-55-8], NaHCO. Soda ash is typically dissolved, carbonated, and cooled to crystallize sodium bicarbonate. The mother Hquor is heated and recycled. The soHd bicarbonate is dried in flash or tray driers, screened, and separated into various particle size ranges. Bicarbonate markets include food, pharmaceuticals, catde feed, and fire extinguishers. U.S. demand was approximately 320,000 t in 1989 world demand was estimated at one million metric tons. 

Underwriters Laboratories 333 Pfingsten Road Northbrook, Id. 60062 Standards for Safety is ahst of more than 200 standards that provide specifications and requirements for constmetion and performance under test and in actual use of a broad range of electrical apparatus and equipment, including household appHances, fire-extinguishing and fire protection devices and equipment, and many other nongenerady classifiable items, eg, ladders, sweeping compounds, waste cans, and roof jacks for trader coaches. 

A series of fire-extinguishing fluids. Halon 1211 is produced hy ICI, and Halon 1.301, hy duPont, the latter issuing a hulletin with thermodynamic properties and a diagram for the range 0.6-600 psia, —160 60 F. 

The term glue-sniffing derives from the abuse of adhesives which often contain solvents such as toluene, ethyl acetate, acetone, or ethyl methyl ketone. These, and similar compounds, also occur in a diverse range of other commercial products which may be abused, e.g. shoe-cleaners, nail varnish, dry-cleaning fluids, bottled fuel gases (butane and propane), aerosol propellents, and fire extinguishers (bromochlorodifluoromethane). 

Combustible liquid flash point 78°C (172°F) fire-extinguishing agent alcohol foam. The range for its explosive limits in air is not reported. 

Flammable flash point 36°C (97°F) vapor density 3.7 (air = 1) the vapor forms an explosive mixture with air, range is not reported. Fire-extinguishing agent alcohol foam a water spray may be used to cool fire-exposed containers and to flush any spill. It decomposes to HCl and tetrahydrofuran on heating. 

Combustible flash point (open cup) 74° C (165°F) ignition temperature 688°C (1270°F) the vapor forms an explosive mixture in air within the range of 2.2-12.0% by volume of air fire-extinguishing agent water spray, CO2, dry chemical, or alcohol foam. 

Highly flammable liquid flash point (closed cup) -17.8°C (0°L) vapor pressure 620 torr at 20°C (68°L) vapor lighter than air and diffuses laterally and upward vapor density 0.9 (air =1) ignition temperature 540° C (1000°L) the vapor forms an explosive mixture with air in the range 6-41% by volume of air fire-extinguishing agent dry chemical, alcohol foam, or CO2 nse a water spray to flush the spill, disperse the vapors, and keep fire-exposed containers cool. 

Flammable liquid flash point (closed cup) 7°C (45°F) vapor density 3 (air = 1) vapor pressure 27 torr at 20°C (68°F) vapor can travel some distance to nearby ignition source and flash back fire-extinguishing agent dry chemical, alcohol foam, or CO2 a water spray can be used in diluting and flushing the spill away from exposure. MIPK forms an explosive mixture with air within the range 1.6-8.2% by volume in air. 

Flammable liquid flash point (closed cup) 36°C (96°F) vapor density 3.9 (air = 1) vapor pressure 4.5 torr at 20°C (68°F) autoignition temperature 425°C (797°F) fire-extinguishing agent alcohol foam or water spray. MIAK forms an explosive mixtnre with air at an elevated temperatnre [93°C (199.4°F)] within the range 1-8.2% by vol-nme of air. 

It forms an explosive mixture with air. The explosive concentration range is not reported. Hazardous when mixed with easily oxidizable compounds. Fire-extinguishing agent water from a sprinkler or fog nozzle from an explosion-resistant location.
