HSNO Regulations - Storage of Class 6 & 8

Storage of Class 6 (Toxics) and Class 8 (Corrosives)

This is another area of significant change, there are now storage requirements for toxics and corrosives, including establishment of hazardous substance locations and compliance certification.  There is a staged implementation period for this to give everyone time to get up to speed.

• 1 Jun 2018
  • storage requirements for class 6 toxic and class 8 corrosive substances that are not located at a hazardous substance location, and on farms
• 1 Dec 2018
  • Storage requirements for class 6 toxic and class 8 corrosive substances at transit depots
• 1 June 2019
  • Storage requirements for class 6 toxic and class 8 corrosive substances at a hazardous substance location
• 1 Dec 2019
  • Compliance certification for class 6 toxic and class 8 corrosive substances at a hazardous substance location

Do I need a Location Certificate?

The thresholds for toxic & corrosive hazardous substance locations have been set as follows:

• Class 6.1A, 8.2A                 50kg or 50L
• Class 6.1B, 8.2B                 250kg or 250L
• Class 6.1C                            1,000kg or 1,000L
• Class 6 or 8 substance specified in a safe work instrument
• Higher thresholds apply to farms greater than 4 hectares
• A safe work instrument can also allow that a HSL is not required

When calculating if you need a location certified, all relevant class 6 & 8 are counted together (unless they are incompatible per Schedule 15 and stored separately).  So if for example you have a store on site that contains products some of which are Class 6.1B and the remaining ones are 8.2B but not 6.1 then all those products need to be considered for the location certification threshold.  

Storage at an HSL can be either in an indoor storage cabinet, or other external or internal store that meets the requirements set out in the regulations.
