Chemical Safety Databases & Data Tabulations

Agency for Toxic Substances and Disease Registry.

  • ATSDR Home Page
  • ATSDR ToxFAQs. Summaries of over 100 hazardous substances developed by the ATSDR Division of Toxicology. Each fact sheet serves as a quick and easy to understand guide. Answers are provided to the most frequently asked questions about exposure to hazardous substances found around hazardous waste sites, including human health effects.
  • ATSDR Minimal Risk Levels (MRLs) for Hazardous Substances. Initial response by ATSDR and EPA to Superfund Amendments and Reauthorization Act requirement to develop priority list of hazardous substances at Superfund sites. This page explains the MRLs and lists 273 oral and inhalation MRLs for 134 pure chemicals, mixtures and chemical products.
  • ATSDR Hazardous Substance Release/Health Effects Database, HazDat. Scientific and administrative database developed to provide access to information on the release of hazardous substances from Superfund sites or from emergency events and on the effects of hazardous substances on the health of human populations.


EcoGopher. No longer exists, but points to an EPA page, Envirofacts Warehouse. Comprehensive data on over 1,500 environmental toxins. Useful Health Hazard summary and Ecological Information, in addition to thorough MSDS information, are provided.


Environmental Protection Agency's Chemical Fact Sheets. Brief summary of information on 31 selected chemicals. The Fact Sheets cover each chemical's identity, production and use, environmental fate, and health and environmental effects. They also include a list of laws under which the chemical is regulated, phone numbers, and the names of EPA offices and other Agencies one can call or contact for more information. Each Fact Sheet is also accompanied by a comprehensive Chemical Summary, a technical support document that provides detailed technical information on the chemical named in the Fact Sheet. Eleven are available in Adobe .PDF Format. All are available as ASCII Text.



EXTOXNET, Extension Toxicology Network.

  • Home Page. A Pesticide Information Project of the Cooperative Extension Offices at Cornell University, Michigan State University, Oregon State University, and University of California at Davis. Major support and funding was provided by the USDA/Extension Service/National Agricultural Pesticide Impact Assessment Program. EXTOXNET primary files maintained and archived at Oregon State University.
  • This source contains over 180 Pesticide Information Profiles on specific pesticides, and
  • Toxicology Information Briefs covering selected concepts and terms in toxicology, all aimed at the non-expert.


National Institute for Occupational Safety and Health.

  • NIOSH is part of the Centers for Disease Control and Prevention (CDC) and is responsible for conducting research and making recommendations for the prevention of work-related illness and injuries.
  • Occupational Health Guidelines for Chemical Hazards. Four to six page guidelines for 468 common chemicals. Includes information on health hazards, chemical and physical properties, and monitoring and measurement procedures. Recommendations provided for respirators, personal protective equipment, common operations and controls, and emergency first aid procedures. References listed. Go to the Master Index for links to individual pdf documents.
  • NIOSH Chemical Listing and Documentation of Revised IDLH Values (as of 3/1/95). Original and revised values for air concentrations considered Immediately Dangerous to Life and Health of 387 substances, with links to the documentation regarding the revisions for each.
  • Introduction to the meaning and use of the NIOSH IDLH values.


National Toxicology Program Home Page. Current work in carcinogenesis, toxicology and genetic toxicology is available in several formats:


  • as complete technical documents in the most recent Biennial Report to Congress:

  -The 10th Bienial NTP Report;

  • And as a searchable index of Chemical Health & Safety Data (From this page you can also view a list of chemicals with links to their Health & Safety Data, or download Macintosh (sea) or PC (zip) archives of these data.)


New Jersey Hazardous Chemical Factsheets. Facts on ~550 chemicals found in the workplace, home and in the environment.


North American Emergency Response Guidebook (NAERG) was developed jointly by the US Department of Transportation (DOT), Transport Canada (TC), and the Secretariat of Communications and Transportation of Mexico (SCT) for use by firefighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving a hazardous material. It is primarily a guide to aid first responders in (1) quickly identifying the specific or generic classification of the material(s) involved in the incident, and (2) protecting themselves and the general public during this initial response phase of the incident. The NAERG, last updated in 1996, is updated every three years to accommodate new products and technology.


University of Akron Hazardous Chemical Database provides access to information for nearly 2,000 hazardous chemicals based on a keyword search. Keywords include chemical names, formula and registry numbers (CAS, DOT, RTECS, and EPA).
