Resources for health professionals

We have developed a tool to help health professionals report hazardous substances injuries and diseases.  

The HSDIRT tool (Hazardous Substances Disease and Injury Reporting Tool) is a GP-based system for reporting hazardous substances injuries and diseases.

This section provides a range of resources about hazardous substances, and the HSDIRT.

These resources will be useful for all medical professionals, including GPs and other primary care health professionals, and the injury prevention sector.

Information about HSDIRT for health professionals

If you are a healthcare professional, you need to use the HSDIRT tool to report injuries and diseases that you suspect are caused by a hazardous substance.

HSDIRT training materials are available to health care professionals and Public Health Unit staff who investigate hazardous substance-related complaints.

You can find useful information about HSDIRT for GPs and Public Health Units (PHUs) below. These resources may be useful in the investigation of a notification, or deciding whether a notification needs to occur. There are some health education resources that would be useful for patients.
