Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. CFCs are nontoxic, nonflammable, and make almost ideal aerosol propellants. The use of flammable ether was displaced by nonflammable fluorinated hydrocarbon anesthetics. It is odourless, insoluble in water, biodegradable, non-allergenic, antistatic and virtually nonflammable. This colorless, odorless, nonflammable gas is produced both industrially and biologically. Modern techniques involve renewable, nonflammable and nontoxic chemicals. The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They are nonflammable and more easily recycled than batteries that employ toxic or flammable materials. It a colourless, hygroscopic, nonflammable, highly reactive gas characterized by a musty odour. This nitrogen-fluorine compound is a colorless, nonflammable gas with a slightly musty odor. They have very similar properties, all being colorless, odorless, and nonflammable. A buffer gas is an inert or nonflammable gas. The solvating agent can be flammable because its mixture with the HFE is nonflammable. Dibromochloromethane is a colorless to yellow, heavy and nonflammable compound with formula . UN1956, Compressed Gases, N.O.S., Nonflammable Gas.
