Extra info for Engineering The Risks of Hazardous Wastes
Both words in the term hazardous wastes are crucial to engineers. Hazard is a component of risk. A hazard is expressed as the potential of unacceptable outcome (see Table 1-1). For chemicals, the most important hazard is the potential for disease or death (measured by epidemiologists as morbidity and mortality, respectively). So, the hazards to human health are referred to collectively in the medical and environmental sciences as toxicity. Toxicology is the study of these health outcomes and their potential causes.
P List. , approximately 100% composition and sole active ingredient) chemicals discarded by commercial operations. • U List. Toxic, but not acutely hazardous, technical-grade chemicals discarded by commercial operations, which are also classified as corrosive, ignitable, reactive, or toxic (see Table 1-1). 2. 3. Based on testing, the waste is found to be corrosive, ignitable, reactive, or toxic (see Table 1-1). The generator of the waste reports and declares that the waste is hazardous based on its proprietary information or other knowledge about the waste.
It is important to remember that the EPA’s reputation at the time of Ruckelshaus’s return was at an all-time low. The public was losing confidence in its ability to protect the environment. 6 In 1983, the National Research Council7 proposed a four-component process that has since been adopted by most public health institutions and agencies in the United States: 1. 2. 3. 4. Hazard identification. The process of identifying the chemical substances of concern, and the compilation, review, and evaluation of relevant data concerning the hazardous properties of the substances, especially their toxicity.
