Hazardous materials are separated into groups based on physical characteristics, such as explosive energy, particle size and conductivity. The hazard classification of a chemical determines what information must be included on labels and SDS to comply with model WHS Regulations. Every hazardous substance imported into New Zealand or manufactured in New Zealand must be approved and have its classifications determined under the Hazardous Substances and New Organisms Act (HSNO). Light (low) hazard areas are locations where the quantity and combustibility of Class A combustibles and Class B flammables is low.
