Non-Flammable Liquid

Carbon tetrachloride is colorless, heavy, non-flammable liquid with a characteristic odor. It has a boiling point of 78 Celsius, and a melting point of -23 Celsius. Carbon tetrachloride is insoluble in water, but miscible with alcohol, benzene, chloroform, ether, and carbon disulfide. Carbon tetrachloride is a potential poison, and inhalation, ingestion, and skin absorption should be avoided at all cost. Carbon tetrachloride may be a carcinogen. It is prepared on an industrial scale by the chlorination of methane, but can be conveniently prepared by reacting chlorine with carbon disulfide in the presence of iron fillings the carbon tetrachloride is recovered by distillation.

NOTE 2 Liquids with a flash point of more than 35 °C may be regarded as non-flammable liquids for some regulatory purposes (e.g. transport) if negative results have been obtained in the sustained combustibility test L.2 of Part III, section 32 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria. 

In another approach, the standard failure frequency is divided over the relevant failure causes only. For example, for a non-flammable liquid without a heating spiral, the failure frequency of 5 x 1per year is now distributed as shown in Table 7. With respect to the original method, the relative contributions of the remaining failure causes are now a factor four higher. However, also in this approach the failure frequency of an atmospheric tank with non-standard measures against a flammable atmosphere would be less than the failure frequency of a tank with an inert substance. 

Methylene chloride (dichloromethane, methylene dichloride) n. CH2-CI2. A low-boiling chlorinated hydrocarbon which is a colorless, fairly dense, non-flammable liquid used as a solvent for cellulose triacetate and vinyl resins, a solvent in the polymerization of polycarbonate resins, and as a reactant for certain phenolic resins. It was widely used as a paint stripper and solvent for cured epoxy resins, but is less used now in the effort to keep chlorinated solvents...

Ease of use in production. An important feature of each raw material in the paint production is the user friendly easy handling making formulated biocides a necessity. Safe, free flowing pumpable, non-flammable liquids with no agressive odors are preferred. A very important example is formaldehyde, which is as such a very aggressive, toxic substance, which can be replaced advantageously by reaction products with amines, alcohols or amides. 

Stationary fuel cell power systems examined for compliance with this standard shall be for use with (a) natural gas, methane gas mixtures and/or (b) liquefied petroleum gases and/or (c) methanol, ethanol (or other alcohol fuel), kerosene, diesel, gasoline (or other liquid hydrocarbons) and/or (d) hydrogen gas and/or (e) Zinc particulate conveyed in a non-flammable liquid medium.
