Pipeline coating and wrapping applies the external corrosion-protection system to a pipeline — factory or field-applied coatings, tapes and wraps, and the field joint coatings applied over the welds after the pipe is joined. The protective coating is essential to the pipeline's integrity over its life, but the work exposes workers to the hazards of surface preparation and coating application: abrasive blasting to prepare the steel surface generates high dust and noise and projects abrasive at high velocity, and the coatings, primers, solvents and adhesives are hazardous chemicals that can be flammable, give off vapours, and harm the skin, eyes and respiratory system. This document is written on the basis that surface preparation and coating are controlled as hazardous-chemical and abrasive-blasting work, with the chemicals managed to their safety data sheets and the blasting hazards contained.
Coating and wrapping is governed primarily by the hazardous-chemicals provisions of the Work Health and Safety Regulations and, where carried out inside a pipe or other confined space, by the confined space provisions — and where it forms part of broader pipeline construction it sits within that high risk construction work. Where the coating or its solvents create a flammable atmosphere, or the work is inside a pipe, the relevant high risk construction work category applies and a safe work method statement is required before the work commences. Pipeline coating systems are applied to the pipeline standard and the coating manufacturer's specification, and the surface preparation and application are controlled for dust, noise, chemical exposure and any flammable atmosphere. This document coordinates the abrasive-blasting, hazardous-chemical and confined space controls so the coating is applied without harming the applicators.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination: use factory-applied or pre-coated pipe and pre-formed field joint systems where practicable, reducing on-site surface preparation and coating and the exposures they create.
- 2Substitution: select lower-hazard coatings and non-silica abrasives, and water or vacuum-assisted blasting methods, where a suitable option exists.
- 3Engineering: local exhaust ventilation and dust containment for abrasive blasting, forced ventilation where coating or blasting is inside a pipe, and vapour control and the exclusion of ignition sources where flammable solvents are used.
- 4Engineering: where the coating, primer or solvent is flammable and could create a flammable atmosphere — particularly in a pipe — atmospheric monitoring and the control of ignition sources.
- 5Administrative: manage the coating chemicals to their safety data sheets — including any isocyanate two-pack systems — with exposure controls, and assess respirable dust where silica-containing abrasive or substrate is involved, applying the crystalline silica controls if relevant.
- 6Administrative: prepare a SWMS where the work is high risk construction work — a confined space such as the inside of a pipe, or a potentially flammable atmosphere — apply the confined space permits and rescue where relevant, and consult the workers.
- 7PPE: respiratory protection appropriate to the blasting dust, coating vapours and any isocyanate — including supplied air for blasting and confined or flammable atmospheres — chemical-resistant gloves and coveralls, eye and face protection, and hearing protection, per AS/NZS 1715 and AS/NZS 1716.
- 8Administrative: all workers must hold a valid White Card (General Construction Induction Training, CPCCWHS1001) before entering any construction workplace, with pipeline and any confined space competencies verified as applicable.
- 9Administrative: conduct a daily pre-start toolbox talk covering the day's work scope, identified hazards, required PPE, emergency procedures, and any changes since the previous shift, and record attendance in the SWMS consultation section.
- 10PPE: eye protection to AS/NZS 1337.1, hearing protection where required, gloves, and Class I or Class II safety footwear with protective toecap to AS/NZS 2210.3.
- 11Administrative: review and update this SWMS whenever the work scope, pipeline conditions or method changes, after any incident or near miss, when a worker or health and safety representative raises a concern, or at minimum every 12 months.
Applicable Codes of Practice
The duties for managing the coatings, primers, solvents and adhesives, including labelling, safety data sheets and exposure control.
The controls for abrasive blasting surface preparation, including dust, abrasive selection, containment and respiratory protection.
Atmospheric testing, ventilation and entry controls where coating or blasting is carried out inside a pipe or other confined space.

Selection, fit testing, use and maintenance of the respiratory protection required for the atmospheric, fume and product hazards of the work.
High-Risk Construction Work triggered
Flammable coatings, primers and solvents — particularly when applied inside a pipe — can create a flammable or contaminated atmosphere, bringing that work within this high risk construction work category and requiring a SWMS.
Coating or blasting inside a pipe or other confined space is work in or near a confined space, with the associated atmospheric, ventilation and rescue controls.
Pipeline coating and wrapping is governed primarily by the hazardous-chemicals provisions of the model WHS Regulations, with the coatings, primers, solvents and adhesives managed to their safety data sheets and exposure controlled. Where the work creates a flammable atmosphere or is carried out inside a pipe or other confined space, those high risk construction work categories apply and a SWMS must be prepared before the work commences, kept readily accessible, and given to the principal contractor if one is appointed. Abrasive blasting is controlled for dust, including any crystalline silica, and noise, and reactive two-pack coatings containing isocyanates require specific exposure controls and health monitoring where applicable. Breaches of the hazardous-chemicals duties and the primary duty of care under the model WHS Act are actively enforced, with offence categories running from failure-to-comply through to reckless conduct. Body-corporate maxima are substantial and indexed; the current maximum follows the prevailing schedule of the responsible regulator.

Worked example
A pipeline coating crew is preparing and coating the external surface of pipe and applying field joint coatings over the welds, with some internal lining work inside large-diameter pipe. Because the solvents and coatings are flammable and some work is inside a pipe, a SWMS is prepared where the work is high risk construction work, and the coating chemicals are managed to their safety data sheets, including a two-pack system containing isocyanates that requires specific exposure controls. Surface preparation is by abrasive blasting with local exhaust ventilation and dust containment, a non-silica abrasive is selected, and respirable dust is assessed; where any silica-containing material is involved the crystalline silica controls are applied. For the in-pipe lining, forced ventilation and atmospheric monitoring control the vapour and dust and maintain a safe atmosphere, ignition sources are excluded because the solvents are flammable, and the confined space controls apply with an entry permit, standby person and rescue arrangements. Applicators wear supplied-air respiratory protection for blasting and in-pipe work, chemical-resistant gloves and coveralls, eye and face protection, and hearing protection. The crew is briefed and signs on, and the chemical, monitoring and application records are retained.

Frequently asked questions
What are the main hazards of pipeline coating and wrapping?
The main hazards are chemical exposure from the coatings, primers, solvents and adhesives — which can be flammable and harmful to the skin, eyes and respiratory system, including isocyanate sensitisers in some two-pack systems — and the abrasive blasting used to prepare the surface, which generates high dust and noise and projects abrasive at high velocity. Where coating or blasting is inside a pipe, confined space and flammable-atmosphere hazards are added.
Is coating and wrapping high risk construction work?
It is governed primarily by the hazardous-chemicals provisions, but it becomes high risk construction work where the coatings or solvents create a flammable atmosphere, or where the work is carried out inside a pipe or other confined space. In those cases a SWMS is required before the work begins, and the confined space and flammable-atmosphere controls apply.
How is the abrasive blasting hazard controlled?
Through local exhaust ventilation and dust containment, selecting a non-silica abrasive and water or vacuum-assisted methods where practicable, assessing respirable dust, and providing supplied-air respiratory protection and hearing protection. Where the abrasive or substrate contains crystalline silica, the crystalline silica controls — including air monitoring and health monitoring for high-risk processing — are applied.
What is the risk from two-pack coatings?
Some pipeline coatings are two-pack systems containing isocyanates, which are respiratory and skin sensitisers — once a worker is sensitised, even low exposures can trigger a reaction. They are managed to their safety data sheets with specific exposure controls, appropriate respiratory protection, chemical-resistant gloves and coveralls, and health monitoring where exposure is significant.
Why is coating inside a pipe more hazardous?
Inside a pipe, coating vapours and blasting dust accumulate with limited ventilation, the atmosphere can become flammable or oxygen-deficient, and egress is restricted. The work becomes confined space work, requiring atmospheric testing, forced ventilation, an entry permit, a standby person and rescue arrangements, with supplied-air respiratory protection and the exclusion of ignition sources where flammable solvents are used.
