You will need to notify the Authority if you use, store or handle hazardous chemicals at your site that exceeds a certain amount (called a manifest quantity). The type of hazardous chemicals and their manifest quantity are set out in Guidance Material and Schedule 11 of the Regulations.
Notifying the Authority will open a notification record about your site. You will need to inform the Authority through a revised notification of any changes to how you will be using, storing or handling hazard chemicals.
Please consult the Contact Officer for more information.
