Gasoline fires

C12-0099. Explain using intermolecular forces whether water can dissolve gasoline. Knowing that gasoline is less dense than water, would you use water to fight a gasoline fire Explain. 

API conducted open pool hydrocarbon fire exposure tests (mostly naphtha and gasoline fires), on process vessels during the 1940 s and 50 s. 

Many states now require fire suppression systems for public service stations and for some private fleet refueling facilities. Most of these systems are dry chemical using infrared detectors and work as effectively on natural gas fires as gasoline fires. No special requirements are necessary few these systems when used at a CNG refueling facility. All fire suppression systems should be checked after installation for proper coverage using a fraction of the dry chemical that would normally be used (this is called a puff test ). The puff test not only shows the coverage that will be obtained, but tests the components of the fire protection system. 

Gasoline and water do not mix, but the former will float in a layer over the latter water is of little effect in extinguishing a gasoline fire. 

Explain why gasoline floats on water. Is water good for putting out gasoline fires ... 

Some use one part roofing tar and one part gasoline. Fire bombs have been found which were made by pouring melted wax into gasoline. 

A possible destruction upon impact of zinc-halogen batteries might lead to the release of chlorine gas or bromine liquid and vapor. A study of the effects of spilling a full load of chlorine hydrate on hot concrete concluded that the probability of lethal accidents appears to be no more serious than that caused by gasoline fires in ICE-powered cars. The bromine vapor pressure above the organic complex is lower than that of chlorine above chlorine hydrate its lethal dose, however, is smaller and the spill cleanup and dispersion problems may be more severe. 

Julian worked for Glidden for seventeen years, developing several new products from soybeans. He mapped out commercially viable syntheses of progesterone, testosterone, and cortisone from soya sterols. From soya protein he developed Aero-Foam, a fire extinguishing foam for oil and gasoline fires, which saw use by the U.S. armed forces during World War II. 

The flasks are designed for exceedingly severe treatment free fall from 9 m onto a concrete floor, 30 min gasoline fire ( —8(X)°C), submersion into 15 m of water, etc., without being damaged. 

Unlike gasoline fires, methanol fires and ethanol fires may be extinguished using water.
