We have tried to make these safety web pages as accurate and useful as possible; however

Please treat this site as a source of general information about safety and the potential hazards of chemicals, not as a definitive statement of the hazards associated with any particular chemical or a reliable interpretation of safety law. If you buy a chemical to use in the laboratory, ask the manufacturer for a complete MSDS sheet.


Acids & Bases - Strengths of Solutions

Buffers

Carcinogens

A list of known and suspected carcinogens.

CAS Numbers - Selected Chemicals

Chemical abbreviations

Safety Data for Common Chemicals

    This section provides links to data in student-friendly format from the HSci project The data provided cover a number of chemicals commonly found in school science labs, some listed by their non-systematic (but frequently-used) names. [A much more extensive list of links to MSDS safety information follows here.]

Consumer and Industrial Products

COSHH

Emergency

Flash Point (Low) Chemicals

Foreign-language databases

    Links to chemical safety data in languages other than English.
     

Gases: Safety Information on Industrial and Scientific Gases

Data are available on a wide range of gases from the BOC group, Matheson and Scott Gas. Tips on the safe handling of compressed gases.

Gas Cylinder Colour Codes

Glossary

A glossary of terms related to chemical safety.

Gloves, Chemically-resistant

    A list of chemically resistant glove material suitable for working with a variety of inorganic and organic chemicals. Information is organized by glove material and by chemical.

Hazard codes (UN)

A list of UN hazard codes is given in the glossary.

Common Highly Toxic Chemicals

Incompatible Chemicals

A list of materials which are incompatible with widely-used chemicals.

Interpreting MSDS Sheets

Laser Classification

    An outline of the scheme used to classify lasers by their potential to cause harm.

Maximum Exposure Limits

MELs have, in the UK, now been replaced by Workplace Exposure Limits.

MSDS (Material Safety Data Sheet) Information

Information on chemicals is ordered alphabetically in the directories below (contents approximately 27,002 distinct names, though the number of substances is smaller because of the inclusion of synonyms). The web pages are not reproductions of 16-point data sheets, but contain key safety information for each chemical. If you intend to use the chemical, we suggest that you obtain MSDS data from your supplier to supplement the data given here, before starting work.

First check the appropriate directory below. If you can't find the chemical you want, try clicking here.

Peroxides

A list of chemicals which may form peroxides during storage.

Risk and Safety Phrases

Most MSDS sheets now contain codes such as R23 or R45 which correspond to certain "risk phrases", and S17 or S24, which correspond to certain "safety phrases". Meanings of these risk phrases as used in the EU are given here, and meanings of the safety phrases are given here.

Shock-sensitive Materials

    A list of materials which, either on their own or in combination with reducing agents, may be shock or friction-sensitive.
