Respirable crystalline silica (RCS) causes silicosis — an irreversible and often fatal lung disease — and is classified as a Group 1 carcinogen by IARC. The WHS Regulation 2025 Part 8A introduces Australia's most significant silica reforms, including a mandatory silica register from October 2025, a binding Code of Practice from February 2026, and a 50% reduction in the workplace exposure limit from 0.05 to 0.025 mg/m3 in December 2026. This template covers all silica-generating construction activities with controls mapped to the new regulatory framework.
WHS Regulation 2025 Part 8A — Respirable Crystalline Silica
Work involving respirable crystalline silica
Managing Respirable Crystalline Silica Dust (binding February 2026 under Section 26A)
Yes — effective February 2026. Non-compliance is admissible as evidence of breach.
| Hazard | Consequence | Likelihood |
|---|---|---|
| Inhalation of respirable crystalline silica dust from cutting, grinding, drilling stone and concrete | Silicosis (irreversible, progressive, fatal) | Likely |
| Lung cancer from chronic RCS exposure (IARC Group 1 carcinogen) | Cancer, death | Possible |
| Accelerated silicosis from high-intensity short-duration exposure | Rapid lung fibrosis, death within 2-5 years of onset | Possible |
| Secondary exposure of nearby workers from uncontrolled dust migration | Silicosis in bystander workers not performing silica tasks | Possible |
| Kidney disease and autoimmune conditions from chronic RCS exposure | Chronic kidney disease, scleroderma | Unlikely |
Workers diagnosed with accelerated silicosis after dry cutting concrete and engineered stone without dust controls. Employers failed to provide health monitoring, exposure assessments, or respiratory protection. Regulator enforcement increasing significantly from 2025.
