The Registry of Toxic Effects of Chemical Substances (RTECS) is a comprehensive database of basic toxicity information for over 100,000 chemical substances including: prescription and non-prescription drugs, food additives, pesticides, fungicides, herbicides, solvents, diluents, chemical wastes, reaction products of chemical waste, and substances used in both industrial and household situations. Reports of the toxic effects of each compound are cited. In addition to toxic effects and general toxicology reviews, data on skin and/or eye irritation, mutation, reproductive consequences and tumorigenicity are provided. United States standards and regulations, NIOSH recommended exposure limits and information on the activities of the EPA, NIOSH, NTP, and OSHA regarding the substance are also included. The toxic effects are linked to literature citations from both published and unpublished governmental reports, and published articles from the scientific literature. Toxicity information appearing in RTECS is derived from reports of acute, chronic, lethal and non-lethal effects of chemical substances. The reviewed information from the scientific literature and published governmental reports plus unpublished test data from the EPA TSCA test submissions database (TSCATS) are included in the file.

Chemical Health and Safety Data
This web page provides Health and Safety information collected on over 2000 chemicals studied by the NTP. Entries for a particular chemical contain chemical identifiers (such as synonyms),physical and chemical information, toxicological data, regulatory information, handling procedures, emergency procedures, and a list of sources for further data on the chemical.
North American Emergency Response Guidebook
The North American Emergency Response Guidebook (NAER) 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:
The NAERG is updated every three years to accommodate new products and technology.
NIOSH Pocket Guide to Chemical Hazards
The NIOSH Pocket Guide to Chemical Hazards is intended as a source of general industrial hygiene information for workers, employers, and occupational health professionals. The Pocket Guide presents key information and data in abbreviated tabular form for 677 chemicals or substance groupings (e.g., manganese compounds, tellurium compounds, inorganic tin compounds, etc.) that are found in the work environment. The industrial hygiene information found in the Pocket Guide should help users recognize and control occupational chemical hazards. The chemicals or substances contained in the current revision include all substances for which NIOSH has recommended exposure limits (RELs) and those with permissible exposure limits (PELs) as found in the Occupational Safety and Health Administration (OSHA) General Industry Air Contaminants Standard (29 CFR 1910.1000). For waste classification purposed, the Pocket Guide is most useful as a tool to determine if a chemical substance possesses acute oral, dermal, or inhalation toxicity.
Environmental Health and Safety Manager (EHS) Internet Library
Safety Management Corporation has provided an excellent internet library containing links to various governmental, university, and private-industry sources containing information useful when classifying hazardous wastes. The following links are indexed in the library:

Computer-Aided Management of Emergency Operations (CAMEO®) Online
CAMEO® is a system of software applications used widely to plan for and respond to chemical emergencies. It is one of the tools developed by EPA's Chemical Emergency Preparedness and Prevention Office (CEPPO) and the National Oceanic and Atmospheric Administration (NOAA) to assist front-line chemical emergency planners and responders. They can use CAMEO to access, store, and evaluate information critical for developing emergency plans. In addition, CAMEO supports regulatory compliance by helping users meet the chemical inventory reporting requirements of the Emergency Planning and Community Right-to-Know Act (EPCRA, also known as SARA Title III). CAMEO also can be used with a separate software application called LandView™ III to display EPA environmental databases and demographic/economic information to support analysis of environmental justice issues.
The CAMEO system integrates a database containing 4,300 chemicals and a method to manage the data, an air dispersion model, and a mapping capability. All modules work interactively to share and display critical information in a timely fashion. The system is particularly useful to characterize the applicability of the acute inhalation toxicity criteria which is an identifier of a hazardous waste. The CAMEO system is available in Macintosh, Windows, and DOS formats.
Chemical Reactivity Worksheet
The Chemical Reactivity Worksheet is software that you use to find out about the potential reactivity of substances and mixtures of substances. To use the Worksheet, you select chemicals from its database, and add them to a "mixture." The Worksheet then predicts the reactivity of this mixture. (There are 4,300 chemicals in the database; these are the same ones that you'll find in the CAMEO chemical database.)
Recommendations for Chemical Protective Clothing
There are many chemicals which can cause adverse effects on unprotected skin ranging from contact dermatitis to permeation of the skin and systemic toxic effects. In addition, some chemicals (mostly solids) can present a contamination problem where inadvertent ingestion (e.g., lead) could occur or re-entrainment in the air stream (e.g., asbestos) could lead to inhalation. Chemical protective clothing (CPC), comprising gloves, boots, suits and other related components, can prevent direct skin contact and contamination.
CPC can also prevent physical injury to the unprotected skin from thermal hazards such as from rapidly evaporating liquefied gases freezing the skin (e.g., LPG).
This site provides CPC recommendations for the chemicals listed in the NIOSH Pocket Guide to Chemical Hazards. For waste classification purposes, the information contained on this site is most useful to classify a waste according to the characteristic of acute dermal toxicity.
Chemical Abstracts Service Substance Count
If you have ever wondered how many chemicals there are registered with the Chemical Abstracts Service (CAS), this site will provide you with an up-to-the minute tally of the number of chemicals in the world. As of December 10, 1999, there are 16,434,909 organic and inorganic substances and 5,871,075 sequences of substances registered for a total of 22,305,984 chemical substance registrations.
This site also provides information on the following CAS databases (data current as of December 10, 1999):
The ECOTOXicology database is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX integrates three U.S. EPA, Office of Research and Development (ORD), National Health and Environmental Effects Research Laboratory (NHEERL), Mid-Continent Ecology Division, toxicology effects databases; AQUIRE (aquatic life), PHYTOTOX (terrestrial plants), and TERRETOX (terrestrial wildlife). ECOTOX is currently the premium source for information related to the acute aquatic toxicity of chemicals.
Chemical Hazard Response Information System (CHRIS) Online
The CHRIS database is not yet online, but this site will provide a link when is becomes available. CHRIS is an excellent source for acute aquatic toxicity data.
Chemical Hazard Labels
The National Fire Protection Association (NFPA) has developed a system for indicating the health, flammability and reactivity hazards of chemicals. This site will provide the labeling information necessary for the chemicals in the site's database and will allow the user to understand what the hazards of a chemical are by information contained on the chemical's label. It is a useful site for determining the characteristics of acute oral, dermal, and inhalation toxicity, as well as for the characteristics of corrosivity, ignitability and reactivity.
Terraserver is a digital imaging service from which the user can access a satellite image of many locations in the United States, Northern Mexico, and Western Europe. The picture can be magnified to provide a resolution of as little as 1 meter. This site is useful to determine the areas at a facility most isolated from sensitive populations and for facility siting purposes.
Hazardous Chemical Database
This database will allow the user to retrieve information for any hazardous chemicals contained in the database determined by a keyword search. Potential keywords include names, formula and registry numbers (CAS, DOT, RTECS and EPA).
