OSHA/EPA Occupational Chemical Database. OSHA and EPA jointly developed and maintain this database as a convenient reference for the occupational safety and health community. This database compiles information from several government agencies and organizations. Available database reports include: "Physical Properties," "Exposure Guidelines," "NIOSH Pocket Guide," and "Emergency Response Information," including the DOT Emergency Response Guide. In addition, an all-in-one report, "Full Report," is available.
The NIST Chemistry WebBook provides users with easy access to chemical and physical property data for chemical species through the internet. The data provided in the site are from collections maintained by the NIST Standard Reference Data Program and outside contributors. Data in the WebBook system are organized by chemical species. The WebBook system allows users to search for chemical species by various means. Once the desired species has been identified, the system will display data for the species.
