""EPA's Clean Air Act Toxics Database"" is a four-volume series of databases that focus on 189 toxic airborne substances regulated by the US Environmental Protection Agency (EPA) as a result of the 1990 Clean Air Act Amendments. Each database features an automatic installation programme, advanced menu-driven search capabilities, and an automatic printing feature that can output data to hard-copy reports or electronic files, which can then be easily imported into popular word processing software packages. The databases will run on any IBM or IBM-compatible personal computer with 640K RAM, a hard drive and at least 1MB of available hard disk space. DOS 2.0 or higher is also required, and a manual is included with each database.;Information provided in ""EPA's Clean Air Act Toxics Database"" has been drawn from EPA reports, ACS-sponsored publications, the National Toxicology Program's Chemical Database, and other sources. The four-volume set represents a complete source for frequently needed information for air toxics sampling and analysis, pollution abatement, regulatory decisions and occupational health and safety support required for complying with the Clean Air Act.;Volume 3, ""Air Toxics Hazardous Properties Database"" lists the hazardous properties of the EPA regulated airborne toxic substances. This information includes potential for fire hazard, lower and upper explosive limits (LEL and UEL), reactivity, volatility and stability data when available. Recommendations for the types of fire extinguisher that may be effective in controlling fires are provided in many cases. This database also provides a field that lists common uses for these chemicals and pertinent comments.
