Worked example
A pipeline coating contractor applies the field-joint coatings on a gas transmission line on a spread in regional New South Wales, abrasive-blasting the welded joints, applying the protective coating, and fitting heat-shrink sleeves before lowering-in. The coating scope runs across several weeks as part of the construction. Before work, the contractor reviews the SWMS against the spread: the coating products are reviewed for isocyanate and solvent content against their safety data sheets, the abrasive-blasting dust and the respirable crystalline silica risk are assessed, and the confined-space tie-in coating locations are identified. The dominant hazards are isocyanate and solvent-vapour exposure from the coatings, respirable crystalline silica and dust from abrasive blasting, the heat-shrink sleeve application, and confined-space work at tie-in coatings, so the SWMS specifies respiratory and skin protection against isocyanate and solvent vapour selected from the safety data sheets and the workplace exposure limits, dust and respiratory controls for abrasive blasting using low-silica or non-silica abrasive where practicable, controlled use of the heat source for the shrink sleeves, and confined-space entry to AS 2865 where tie-in coatings are applied in a restricted space. Vapour exposures are monitored where the coatings are applied. The coatings are applied, the sleeves fitted, and the joints protected. The product, exposure, and blasting records are documented, and the coating scope is completed without an isocyanate or solvent overexposure or a silica incident, with the records retained for the operator.

Frequently asked questions
Why is isocyanate exposure a specific hazard in pipeline coating?
Many protective pipeline coatings are isocyanate-based, and isocyanates are respiratory sensitisers that can cause occupational asthma, with a low workplace exposure standard, so the SWMS specifies respiratory and skin protection against isocyanate exposure selected from the coating safety data sheets and the exposure limits, with monitoring. The protection is matched to the specific product. Because isocyanate sensitisation can occur at low exposures and is often irreversible, the isocyanate controls are treated as a health-critical element of the coating work.
How is the abrasive-blasting silica hazard controlled?
Abrasive blasting to prepare the joints can generate respirable crystalline silica, both from silica-containing abrasive and from the surface, so the SWMS specifies dust and respiratory controls and the use of low-silica or non-silica abrasive where practicable. The respiratory protection is selected for the blasting exposure. Because silica is a recognised carcinogen and blasting is a high-exposure activity, the abrasive selection and the respiratory controls are treated as health-critical, alongside the isocyanate and solvent controls.
Why is pipeline coating high-risk construction work?
It involves isocyanate and solvent-vapour exposure, respirable crystalline silica from abrasive blasting, a heat source for shrink sleeves, and confined-space work at tie-in coatings, with several elements engaging the high-risk categories for hazardous atmospheres and confined spaces. A respiratory sensitisation, a silica overexposure, or a confined-space atmosphere incident presents a serious hazard. A SWMS is required, with vapour and dust controls, heat-source controls, and confined-space controls as central elements.
What changes for the 1 December 2026 exposure-limit transition?
Workplace exposure standards are being revised with a transition taking effect on 1 December 2026, and the limits for some solvent and coating constituents are among those affected, so the SWMS is written to control vapour exposures against the applicable limits and to verify them by monitoring. Where a constituent's limit tightens, the ventilation and respiratory controls are reviewed against the new figure. The SWMS treats the exposure standards as current drivers so the coating controls remain compliant through the transition.
When does the coating work require confined-space controls?
Where field-joint or tie-in coatings are applied in a restricted space — such as a bell-hole, a pit, or a tie-in excavation — the work can be confined-space work under AS 2865, and the solvent and isocyanate vapours can accumulate in that space. The SWMS specifies confined-space entry to AS 2865 where coatings are applied in a restricted space, with atmospheric testing for the vapours. Applying solvent-based coatings in a confined space without atmospheric and entry controls risks a vapour accumulation, so the confined-space controls apply in those locations.
