Methyl mercaptan is a flammable, toxic, reactive, irritating gas with a strong, disagreeable odor (similar to that of garlic or rotten cabbage) that is detectable at extremely low concentrations. Common uses of methyl mercaptan include in the manufacturing of additives for jet fuels, catalysts, dyes, fungicides, pesticides, pharmaceuticals, plastics, and other chemicals. The name methyl mercaptan is slowly being replaced by its proper chemical name methanethiol, although the U.S. Department of

Over the summer, my family and I had the pleasure to visit Pennsylvania Dutch country. We decided to tour an Amish home, complete with all the furnishings and devices used. One that took me by surprise was a standard kerosene lamp converted to LP gas. Under the lamp was a cabinet that contained a 20-pound gas tank.

Silicon tetrachloride is a water-reactive, toxic, corrosive, irritating, mobile, volatile, colorless to light yellow-colored fuming liquid with a sharp, pungent, suffocating odor. It is commonly used in the production of compounds such as ethyl silicate, high purity silica, various silicone compounds, fused silica glass, and other chemicals. It reacts vigorously with water, liberating heat, hydrogen chloride (which dissolves in the water to form hydrochloric acid), and siloxane.

Formic acid is a combustible, corrosive, toxic, irritating, colorless liquid with a pungent odor. In its natural state, it is the major ingredient in the stinging chemical of ants and other insects. Its main uses are in dyeing textiles and as an organic chemical intermediate used in the production of other chemicals such as fumigants, insecticides, perfume solvents, refrigerants, and vinyl resin plasticizers. It is also used as an antiseptic, a laboratory reagent, an ore flotation agent, and a

Boron trichloride is a corrosive, toxic, irritating, nonflammable, colorless gas usually found as a fuming liquid. Used in many chemical processes and in the manufacture of many chemicals, it is found in chemical facilities where aluminum, copper, magnesium, and zinc are refined to remove carbides, oxides, and nitrides from the molten metals. It may also be found wherever diborane, electrical resistors, soldering fluxes, or optical fibers are produced.

Chlorine dioxide is an oxidizing, unstable, reactive, toxic, irritating, yellowish-to-reddish gas with a pungent odor resembling chlorine or nitric acid. The U.S. Department of Transportation (DOT) forbids the transport of pure chlorine dioxide, which normally is diluted to less than 10 percent in a cold solution and shipped as a hydrate in its frozen form resembling orange-colored ice. It is used as a bleaching agent for beeswax, fats, flour, leather, oils, textiles, and wood pulp; in water-tr

Sodium hydrosulfide is a water-reactive, toxic, corrosive, irritating, colorless-to-lemon-colored, flammable solid with an odor of rotten eggs. Its common uses include bleaching; chemical milling solutions; the dehairing of animal hides; glassmaking; ore flotation; paper pulping; the processing of dyestuffs; and the manufacture of cellophane, rayon, and many chemicals.

Propylene oxide is a flammable, toxic, irritating, highly volatile, colorless liquid with a sweet odor resembling alcohol and ether. Its odor may be detected at levels as low as 10 ppm (parts per million of air). It is used to manufacture brake fluids, detergents, fumigants, propylene glycol, ingredients of polyurethane foam, and synthetic lubricants. There is some evidence that propylene oxide may be a carcinogen.
