Hazardous Substance Register
Updated: Dec 19, 2021
Hazardous Substances refer to chemicals or substances which can be toxic, corrosive
and cause harm to people, animals or the environment. It is important that we document what substances are on site, when they are on site, and how they are stored.
There are processes, by law, that need to be followed to ensure that all hazardous substances are stored, used and disposed of correctly to reduce the risk to anyone that
uses or comes into contact with them. The best way to do this is by having a Hazardous Substance Register.
What is a Hazardous Substance?
As the register represents the maximum amount of the substances held, it means it
does not require updating on a daily basis, but reviewed on a regular basis (quarterly
or 6-monthly), especially when maximum quantities change or products used (brand or
specific product) change.
What to include on the register:
A Hazardous Substance Register should include all hazardous substances that
are used, handled or stored on a site or workplace (including hazardous waste).
The register should include:
The substance name
The maximum quantity to store
Where it can be found on site
UN number of the substance
Specific storage requirements
Any key information from the Safety Data Sheet (SDS)
What to do in an Emergency
Any information about waste
Current Safety Data Sheets for each substance and emergency information/ equipment
must be immediately available at all times.
A hazardous substance is any product or chemical that has explosive, flammable,
oxidizing, toxic, corrosive or ecotoxic properties.
Explosive - Explodes or causes explosion
Flammable - Ignites easily and burns rapidly
Oxidizing - Could be gaseous, solid or liquid and can cause or intensify fire and explosion
Toxic - Can harm people if it enters the body through contact, being inhaled or ingested. The effects can range from mild to life threatening and can be immediate or long term.
