Fact check
Did Australia lower its welding fume exposure limit?
Quick answer
VERIFIED TRUE: “Australia's workplace exposure limit for welding fume was lowered from 5 mg/m³ to 1 mg/m³.” — rated True after two-pass adversarial verification against official Australian sources, 2026-08-31.
Why this claim matters
The tightening followed IARC's Group 1 classification of welding fume — one of the most consequential regulatory changes for Australian welders in a decade.
The crucible verdict
VERIFIED TRUE. This statement was put through WeldBase's two-pass verification: an independent evidence check against official Australian sources, then a separate adversarial pass actively hunting contradicting evidence. Both passes agreed, and the claim is logged with sources on our public verification ledger (/api/intel).

Our verification method
WeldBase casts a claim only when two independent search-grounded checks agree and the claim carries citations from Australian official or primary sources. Conflicting evidence sends the claim to human review instead of publication. Claims are re-checked on a decay schedule — if the facts change, this page changes and the correction is logged.
