Australia Introduces New Legal Limit for Flour Dust — Effective December 2026

Major change ahead for food manufacturers and bakeries: for the first time, flour dust now has a dedicated workplace exposure limit — 0.5 mg/m³ (8-hour TWA) under Australia’s new Workplace Exposure Limits (WELs) framework.

This is a tenfold reduction from old benchmarks, meaning air monitoring, improved ventilation, and updated PPE programs will be essential before enforcement begins.

These updates form part of wider national reforms lowering exposure limits across multiple industries — including diesel exhaust, asphalt fumes, and wood dust.

iiNexus Global’s EHS team is already helping workplaces measure exposure, upgrade controls, and prepare compliance documentation.
