The safe handling of chemicals requires an understanding of their properties, hazards, and measures for handling emergencies involving them. This information can be found on the compound's MSDS.

MSDS is an acronym for material safety data sheet. The purpose of the MSDS is to inform chemical users of the hazards potentially encountered with their use. Both the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) have published regulations dealing with MSDS.

The ANSI Z400.1 format for MSDS incorporates all the information required under the OSHA Hazard Communication Standard (plus a few extras). The ANSI format lists sections in a logical sequence and has gained acceptance by most manufacturers and distributors. It is usefull to understand what information is contained in each section of the MSDS.
