The Hazardous Substances and New Organisms Act (HSNO) 1996 has been in force for hazardous substances since 2001. It is administered by the EPA who imposes controls on any approved used of Hazardous Substances.
Anyone involved in the handling, sale or servicing of any of these substances must comply with the controls, throughout the life cycle of the substance.
As a business owner you are responsible for ensuring that your site complies with the relevant parts of the HSNO legislations including signage and separation distances.
A residential customer using LPG for heating will also have to obtain a Location Test Certificate for larger containers greater than 100kg in total.
