We use hazardous substances every day and in all sorts of ways. Some are so commonplace that we don't even realise that they're dangerous - but they are.
So we need to be sure about what's hazardous, what's not and how to handle and dispose of the dangerous ones. But do you know how to do that?
That's where the Hazardous Substances and New Organisms Act 1996 (HSNO) comes in.
The HSNO Act pulls together the management of hazardous substances into one law that focuses on all of their hazards - to you and to the environment. It makes sure you have enough information to use and dispose of them safely.
A substance is hazardous if it has one or more of the following properties:
Oxidiser and organic peroxide
Information provided by the manufacturer, supplier or retailer (typically, this would be as a label on the package or container) should tell you:
There may be additional information - for instance in the package or attached in a plastic sleeve - depending on its type and degree of hazard.
A hazardous substance supplied to a workplace must be accompanied by more detailed documentation on:
When a substance is packaged for transport, the package must have a placard or label indicating its type and degree of hazard and the driver must carry documentation identifying the substance and the hazards it presents.
All hazardous substances should have disposal instructions on their labels or in the accompanying information. Generally, disposal should be by treatment by a hazardous waste management operator or disposal to suitable landfills in accordance with their acceptance criteria, or, in certain cases, to sewer, in accordance with your local authority's trade waste acceptance criteria.
You can call Councils Environmental Monitoring Officer for advice on disposal.

The HSNO Act is enforced by a number of central and local government agencies, such as hazardous substances staff employed by councils and Occupational Safety and Health staff at the Department of Labour. Enforcement agencies will monitor compliance with the HSNO Act and regulations and conditions set by ERMA. They can issue compliance orders and infringement notices and prosecute offenders when an order is not complied with. Enforcement agencies can also advise you on how to comply with the HSNO Act and regulations.
|Keep substances in their proper container||Store in a way that damages the packaging|
|Read the label||Store or use where unauthorised people - particularly children - can gain access to them|
|Make sure that labels do not get damaged||Deposit in landfill or down drain without first checking that it is allowed|
|Read any additional information supplied with the substance or package||Detonate or burn substances other than fuels unless qualified to do so|
|Keep all the information|
|Clean up spills quickly provided this can be done in a way that protects you and the environment|
The manufacturer, supplier or importer should provide you with a contact number for more information. The enforcement agencies, particularly the hazardous substances experts in local authorities and the Occupational Safety and Health Service of the Department of Labour as well as ERMA New Zealand (Environmental Risk management Authority), are able to give you advice when dealing with hazardous substances. They can help you determine if you need an emergency plan and give you advice on how to prepare one.
ERMA New Zealand is an independent body established under the HSNO Act. Its role is to assess the environment and health risks and to place controls to make sure that these are managed properly. It maintains a public register of all approved hazardous substances - including the controls on each substance - and produces guides and other resources for dealing with hazardous substances.
