Danger characteristics

SPECIAL WASTE Controlled waste which is subject to special regulations regarding its control and disposal because of its difficult or dangerous characteristics. The UK definition of special waste is similar, but not identical, to the EC s hazardous waste. 

The Toxic Substances Control Act of 1976 was enacted by Congress to test, regulate, and screen all chemicals produced or imported into the U.S. Many thousands of chemicals and their compounds are developed each year with unknown toxic or dangerous characteristics. To prevent tragic consequences, TSCA requires that any chemical that reaches the consumer market be tested for possible toxic effects prior to commercial manufacture. Any chemical that poses health and... 

It can therefore have the dangerous characteristics of both the alcohol and acid functions. Besides, methyl groups can be involved in reactions that affect the C-H linkage. Starting with the acid function discussed in chapter 6 there are the following factors to take into account ... 

The action of sulphuric acid on chlorates produces chlorine dioxide and possesses the dangerous characteristics of this substance. Incorporating a drop of sulphuric acid into a mixture for Bengal lights produces spectacular results. The acidic character of sulphur dioxide would be sufficient also to convert chlorates into chlorine dioxide, but a temperature of 60°C is needed to do so. 

Also, US-EPA has mechanisms in place to track the thousands of new chemicals that industry develops each year with either unknown or dangerous characteristics. US-EPA then can control these chemicals as necessary to protect human health and the environment. TSCA supplements...

Flammability. Flammability of cotton fabrics is not a dangerous characteristic, but certain uses require flame resistance. Impregnation of fabrics with certain inorganic salts such as borax-boric acid and ammonium sulfamate and with chlorinated organic compounds has been used. Other methods have been proposed but have not become generally useful. One of these is the urea-phosphate process and another is the Erifon process. 

Flammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example paints, varnishes, lacquers, etc., but not including substances otherwise classified on account of their dangerous characteristics) which give off a flammable vapour at temperatures of not more than 60.5°C, closed-cup test, or not more than 65.6°C, open-cup test, normally referred to as the flash point.
