GHS Hazard Category:
GHS Hazard Category/s can be found in ‘Section 2: Hazards Identification’ of the SDS. This will not be a code but a sentence describing the Category (see attachment for full code list).
NPC has a drop-down list of all the relevant categories. It is a repeatable field in the NPC, so all GHS categories recorded in the SDS should be entered into the NPC.
