What is the difference between direct and bibliographic databases?
Direct databases provide discrete information on a specific substance (e.g. for gasoline: physical properties, LD50, fire hazards, environmental effects, safety procedures, etc.). Bibliographic databases list references and sometimes summaries of reports, journal articles, publications, on a particular topic. Sometimes the topic is a chemical. For example, searching on the subject of gasoline might provide a number of database records which reference printed sources on gasoline or topics related to gasoline (e.g. hazards of underground gasoline storage tanks, gasoline accident reports, incidents of gasoline poisoning).
Chemical
Which chemical database product is best for me?
SDS Database is best for users who need safety data sheets on specific chemical products used in their workplaces.
CHEMINFO provides detailed health and safe handling information on industrial chemicals and ingredients found in products.
CHEMpendium is best for users with a wider range of chemical data needs, such as for both workplace and environment safety, or for workplace, transport and emergency response. It contains numerous and distinct databases all searchable by the chemical name or CAS registry number.
RTECS is best for users who need specific toxicity data on a large number of chemicals. Summaries citing irritation, LD50s, carcinogenicity tests, plus some regulatory data like exposure limits are available for a very large number of chemical substances.

SDS Database FAQs
The SDS Database contains a wide variety of English and French safety data sheets. You can subscribe to just the English or the French collection, or both.
Can I search by CAS number?
Yes. If the product itself has a CAS number, in most cases, this will be found in the Product Name/ID index. CAS numbers for individual ingredients often appear in the Safety Data Sheet index. Since many of the data sheets are for chemical products with several ingredients, only a small percentage have product CAS numbers.
Where do the data sheets come from?
Safety data sheets are obtained from manufacturers and suppliers, and they are responsible for the content of their safety data sheets.
Where can I find the lists of companies in the SDS Database?
You can find a list of manufacturers and suppliers in the search area on the left side of the page. You can also search by manufacturer or supplier name using the top search bar.
Some data sheets are older than 3 years. Is this permissible?
The requirement to update a material safety data sheet every three years, as was the case under WHMIS 1988, no longer applies. For WHMIS 2015, the safety data sheet must be accurate at the time of every sale or importation of the hazardous product. Suppliers have an ongoing responsibility to make sure safety data sheets and labels are accurate and compliant.
Do you have lab chemicals? Pesticides? Pharmaceuticals?
The SDS Database contains data sheets for all kinds of chemical products -- industrial products, consumer products, laboratory chemicals, paints, petroleum products, pesticides, pharmaceuticals, food additives, etc.
Can I use the SDS Database instead of keeping paper data sheets?
Yes. Online access to safety data sheets meets WHMIS regulations which require that safety data sheets be readily available in the workplace. However, not all products used in your workplace may be included in the SDS Database. For customized safety data sheet needs, our CANManage service may be a better option.
What makes CCOHS’ SDS Database different? Why should I use this
database when there are safety data sheets freely available on the Internet?
- There are many sources of data sheets available these days, and sometimes we’re asked to include miscellaneous collections of data sheets in the SDS Database. However, the quality and currency is often questionable, and we frequently already have more current information in the database direct from the original source.
- Some other databases contain ”safety data sheets” for non-chemical products, such as pencils, desks, etc., and are not necessarily intended for health and safety purposes. Some contain many outdated data sheets, often decades old. Often there is no indication of how, or from where, the data sheets were acquired.
- Some companies may make their own data sheets available online for their customers, each using their own search engine. If you have many different suppliers, it is more convenient and efficient to be able to access and search many collections of data sheets in a single place.
As a subscriber, how can I add my suppliers’ data sheets that are
not currently in the SDS Database?
For customized safety data sheet needs our CANManage service may be a better choice. CANManage is a customized online solution that pulls all your safety data sheets into one central location to help you meet your compliance requirements.
CHEMINFO FAQs
CHEMINFO is provided through two CCOHS products - CHEMINFO and CHEMpendium. For more information on these products, also refer to the CHEMpendium FAQs.
Who writes CHEMINFO Profiles?
CCOHS staff write CHEMINFO Profiles. Scientists and professionals with expertise in toxicology, human health hazard assessment, chemistry, fire hazard assessment and control and occupational hygiene write and review CHEMINFO Profiles. These chemical profiles are currently an exclusive CCOHS product.
What sources do you use to write CHEMINFO Profiles?
CHEMINFO Profiles are written using rigorous procedures to ensure high quality. The hazard assessment sections (fire, reactivity and health) are written by scientific staff following extensive consultation of original literature, reliable reviews and textbooks. We rely almost exclusively on peer-reviewed, primary scientific data to write the hazard assessment sections in each CHEMINFO Profile. The key original literature is referenced. Some of the hazard control sections, for example Personal Protective Equipment, are written using specific sources which we feel set the industry standard for a particular type of information. Other hazard control sections, for example Storage and Handling, are written by scientific staff at CCOHS following consultation of relevant literature and a complete evaluation of the specific hazards and properties of a chemical.
A list of sources we commonly consult in developing CHEMINFO Profiles can be found in the database’s Help section. The original literature and other specific sources used are referenced in the bibliography of each record.
Why do you have short and long records?
Short records contain readily available information from sources which CCOHS has identified as being reliable and credible. Therefore, the short records require less evaluation by scientific staff, yet provide good quality, useful information for many important chemicals. Typically, these records contain identification information, physical and chemical properties, occupational exposure limits, methods for sampling and analysis, selected fire fighting information, carcinogenicity evaluations, respiratory selection guidelines, information on resistance of materials for glove selection, U.S. and Canadian transportation information and European Union classification information. As resources permit, short records are turned into long records based on our priority list.
In long records, the hazard assessment sections are completed following extensive consultation of original literature, reliable texts and reviews. The hazard control measures are determined based on the hazard assessment information and a complete summary is written. Development of long records takes more time because the hazards of each chemical are evaluated and summarized individually.
Do CHEMINFO records have exposure limits?
Yes, you will find exposure limits in the "Exposure Guideline" part of Section 8 - Exposure Control. In CHEMINFO, you will find:
- Threshold Limit Values (TLV) from the American Conference of Governmental Industrial Hygienists (ACGIH).
- The Permissible Exposure Limits (PEL) from the United States government.
- The Workplace Environmental Exposure Level Guides (WEEL) from the American Industrial Hygiene Association.
CHEMpendium™ FAQs
The CHEMpendium collection provides complete chemical hazard information for your workplace and the environment in one convenient location.
Why are there so many different databases available in
CHEMpendium?
All of the databases contain complementary chemical data and were selected for inclusion based on the scope of the information they provide. With ever-changing requirements in workplaces, many users need data outside the scope of workplace health and safety, such as transport or environmental data. This collection of databases was designed to meet these broad needs.

How often is Environment Canada's Domestic Substances
List/Non-Domestic Substances List (DSL/NDSL) database updated?
The database is updated as amendments are published in the Canada Gazette and are reflected in the next quarterly update of the product. Changes to the inventory are made through the New Substances Program under the Canadian Environmental Protection Act 1999 (CEPA, 1999), a shared responsibility between Environment Canada and Health Canada.
RTECS® FAQs
What kinds of substances are in RTECS?
Generally, RTECS includes drugs, food additives, preservatives, ores, pesticides, dyes, detergents, lubricants, soaps, plastics, extracts from plant and animal sources, plants and animals which are toxic by contact or consumption, and industrial intermediates and waste products from production processes. Users will not find Trade Name products representing compounded or formulated mixtures (pure chemical trade name products are listed).
There is a lot of detailed data in RTECS®. Is there a guide on
how to use and interpret
this information?
A tab called GUIDE in the database includes a publication called "RTECS - A Comprehensive Guide". This document provides information about the format, content and policies of the Registry. It can help you understand the meaning behind the content of each record (eg. the "Mild" category for the Skin Irritation tests means a well-defined erythema and slight edema (edges of area well defined by definite raising) and the reason for its inclusion.
What is the difference between RTECS and HSDB?
RTECS contains toxicity and regulatory information on over 194,000 chemicals, while HSDB has a wider range of subject coverage (over 100 fields) such as medical surveillance, first aid, emergency response, safety measures, health hazards, etc. for 6,000 chemicals. RTECS is a better choice if you need toxicity information on a very large number of chemicals, but HSDB is better if you need safety and other related details.
Bibliographic
What is the difference between direct and bibliographic databases?
Direct databases provide discrete information on a specific substance (e.g. for gasoline: physical properties, LD50, fire hazards, environmental effects, safety procedures, etc.).
Bibliographic databases list references and sometimes summaries of reports, journal articles, publications, on a particular topic. Sometimes the topic is a chemical. For example, searching on the subject of gasoline might provide a number of database records which reference printed sources on gasoline or topics related to gasoline (e.g. hazards of underground gasoline storage tanks, gasoline accident reports, incidents of gasoline poisoning).
