Flammability and Explosion Hazards

The flammability and explosive hazard of ferrosilicon powder is increased substantially during grinding in a vibratory mill [1], Explosion hazards from air-hydrogen,—acetylene, or—propane mixtures formed during preparation of ferrosilicon containing alkaline earth additives are attributed to contact of barium or magnesium carbide or silicide additive with atmospheric moisture [2],... 

Chemical Exposure Index (CEI) (Chemical Exposure Index, 1994 Mannan, 2005, pp. 8/22-8/26.) The CEI provides a method of rating the relative potential of acute health hazard to people from possible chemical release incidents. It may be used for prioritizing initial process hazard analysis and establishing the degree of further analysis needed. The CEI also may be used as part of the site review process. The system provides a method of ranking one risk relative to another. It is not intended to define a particular containment system as safe or unsafe, but provides a way of comparing toxic hazards. It deals with acute, not chronic, releases. Flammability and explosion hazards are not included in this index. To develop a CEI, information needs include... 

Generally, flammability and explosive hazards outweigh the biological effects. ... 

Such reactions can pose flammability and explosion hazards. Another hazard occurs during combustion in an oxygen-deficient atmosphere or in an automobile engine, in which significant quantities of toxic carbon monoxide (CO) are produced. 

The nature of ethylene oxide and, to a lesser degree, the higher alkylene oxides, because of their high reactivity, flammability and explosion hazards mean that plants handling these reactants must be designed to eliminate all possible ignition sources. Reactions must be operated in inert conditions and have explosion pressure rated plant design [ 1-4]. 

An original version of the static method was proposed by Luskina et al. [48], using a simple instrument. Sample compounds were oxidized in a sealed tube in the presence of copper oxide at a residual pressure of lOmmHg. This method of combustion helps to eliminate the disadvantages inherent in the conventional methods of oxidation, namely, the admission of unburned products into the analysis zone and flammability and explosion hazards. All of the combustion products were forced by a flow of helium from the combustion tube into the chromatographic column where separation took place thus the method makes it possible to dispense with special sampling devices. The separation of water from carbon dioxide was effected in a flow of helium in a column of tricresyl phosphate (0.6 m x 3 mm I.D.).
