Do construction (residential and commercial) businesses need to maintain Hazardous Chemicals Register + manifest (WHS Reg)?
A computed answer from the Rules Mate applicability engine, with the exact condition, the outcome for every structure and size, and the primary source.
Short answer: Only if
Only if you use, handle or store hazardous chemicals. Being in this industry makes the obligation worth checking (Industry: Construction (residential & commercial)), but the trigger is a fact the industry alone does not settle.
The obligation in brief
Maintain Hazardous Chemicals Register + manifest (WHS Reg). Model WHS Regulations Chapter 7 require PCBUs handling hazardous chemicals to: identify, maintain a register (SDS + quantities), maintain a manifest if quantities exceed Schedule 11 thresholds, notify the regulator + manage risks (control + storage + emergency planning).
Trigger: Holding hazardous chemicals.
Why construction (residential & commercial) get a different answer
Rules Mate runs its applicability engine across 9 business structures and 6 size bands for each of the 35 industries it maps. For 31 of those industries the answer for "Maintain Hazardous Chemicals Register + manifest (WHS Reg)" is no. Construction (residential & commercial) is one of the 4 where the answer is different: only if.
The deciding fact for construction (residential and commercial) businesses: Industry: Construction (residential & commercial); applies only if you use, handle or store hazardous chemicals.
About the industry: Builders, contractors, and subcontractors covered by the Building & Construction General On-site Award and high-risk WHS.
Compare a professional services (general) business with 6–19 employees structured as a Pty Ltd company: the obligation does not apply (Requires industry: Manufacturing / Mining & resources / Agriculture, forestry & fishing).
Answer by business structure and size
Each cell is the engine's outcome for a business in construction (residential & commercial) with that structure and size, assuming it sells to consumers and small businesses and holds customer contact details. "Check" means the obligation turns on a fact the industry does not settle.
