Can be divided into oral, cutaneous, and respiratory toxicities.   Adsorption Adsorption is a surface phenomenon that some products exhibit, whereby they form a physicochemical bond with substances. Not to be confused with absorption.   Aerosol spray A means of atomizing liquids by propelling them from a pressurized container by a soluble gas.   Alcohols A series of hydrocarbon derivatives with at least one hydrogen atom replaced by an -OH group. The simplest alcohols (methanol, ethanol, n-propanol, and isopropanol) are good solvents for some organic soils, notably rosin, but are flammable and can form explosive mixtures with air: their use requires caution and well-designed equipment.   Anion A negatively charged ion.   Aqueous cleaning Cleaning parts with water to which may be added suitable detergents, saponifiers, or other additives.   Azeotrope A mixture of chemicals is azeotropic if the vapor composition is identical to that of the liquid phase. This means that the distillate of an azeotrope is theoretically identical to the solvents from which it is distilled. In practice, the presence of contaminants in the solvent slightly upsets the azeotropy.   ACGIH American Conference of Governmental Industrial Hygienists   AIHA American Industrial Hygiene Association   | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z | State Information | Glossary | Conversion Checklist | Comments Home | Process Advisor | Alternatives | Links | Search All SAGE material, Copyright© 1992, Research Triangle Institute Last Update: 09 March 1999 sage@rti.org http://clean.rti.org/gloss.cfm?letter=A
