An occupational health database designed for health and safety professionals and for consumers seeking information about the health effects of exposure to chemicals and biologicals at work. Haz-Map links jobs and hazardous tasks with occupational diseases and their symptoms. Chemicals and biological agents in Haz-Map are linked to industrial processes and other activities such as hobbies. Occupational diseases and their symptoms are associated with hazardous job tasks and possible exposure to hazardous agents. Information from textbooks, journal articles, and electronic databases such as NLM's Hazardous Substances Data Bank (HSDB®) is classified and summarized to create the database. Some of Haz-Map's features include: text search capability, browsing by jobs, diseases, or agents, searching hazardous agents by adverse effects, searching diseases by jobs and findings, and automated searches of TOXNET. Definitions of technical terms are available by selecting hyperlinks to the glossary.
