Welcome to the Chemical Hazard Assessment and Prioritization (CHAP) website!

Chemical safety within the workplace is important. However, understanding how hazardous different chemicals are can be difficult. Small and medium-sized workplaces often get much of their information on chemicals from the Safety Data Sheets, external link that come with each chemical. The Safety Data Sheets have information on how hazardous the chemical is, and on the correct use of the chemical. The CHAP tools are designed to help you use information from Safety Data Sheets to better understand (assess and prioritize) the hazards of chemicals you use in your workplace.

The CHAP tools are available in paper and electronic versions for free download. They are offered under Creative Commons Licence CC BY-NC-ND 4.0, external link
