Substance hazards have the potential to harm the health or safety of persons in the workplace including substances which may be produced in the workplace (eg .from welding rods, plastics Proceduring etc.). This information can be stored with each chemical in the Substance Library and will be copied to each Procedure using the selected chemical.

The Australian National Commission has defined a Hazardous Substance as a substance that: is included in the Australian National Commission's List of Designated Hazardous Substances (about eight hundred substances); or meets the criteria for a hazardous substance in the National Commission's Approved Criteria for Classifying Hazardous Substances. It excludes certain substances whose presence or use is not related to a work activity, being foodstuffs, therapeutic agents, cosmetics, tobacco and its products and toiletries and toilet products. This information should be in the MSDS form for the chemical substance.

The following 3 categories of Hazard information can be stored with each chemical substance.

	Caution
	Updating the Hazards information in the Substance Library will also update this information within each Procedure using the selected Chemical. This can possibly change the assessment previously made on those Procedures and require a new assessment to be made. For example a chemical is discovered to be more hazardous than was previously known.
