Hazmap Conclusion

Haz-Map is an occupational health database designed for health and safety professionals and for consumers seeking information about the health effects of exposure to chemicals and biological agents. The database is a "map" of workplace hazards to help you prevent occupational diseases. Haz-Map links jobs, hazardous tasks with occupational diseases and their symptoms, and other non-occupational diseases such as hobbies.

In addition to the ways shown here, there are several other ways to find connections between workplace exposures and disease, including job tasks, occupational diseases and symptoms or medical findings. Explore Haz-Map on your own to discover more connections.
