The NIOSH website of databases is one of the premier sites for Hazardous Material Information, Chemical identity, Sampling techniques, Health statistics and symptoms of exposure. NIOSH has prepared a database of chemical protective clothing recommendations for use in hazmat workers entering sites for chemicals in clandestine drug labs, spill response, chemical production facilities, and general household chemicals.
The Department of Transportation Emergency Response Guidebook for Hazmat workers, police, fire department and first responders. The guidebook is an excellent reference for hazardous material workers who need isolation distances and community protection during spills in transportation related incidents.
