What this pack is
Asphyxiation from argon and carbon dioxide purge gas, awkward pipe-rolling postures, and radiographic testing exclusion zones.
Each industry here is a complete risk assessment for one kind of workshop, with the hazards and their starting ratings already identified by a Certified Industrial Hygienist. You answer Yes, No or N/A to the controls, and the calculator works out your residual risk, builds the Action Plan and produces the finished report.

The most serious hazards in pipe and spool shop
A sample of the 59 hazards in this assessment, each shown with its consequence and the starting risk rating given by a Certified Industrial Hygienist before any controls are counted. The controls themselves are in the calculator.
Stainless releases hexavalent chromium and nickel, galvanised releases zinc, coated pipe releases lead and chromate, and lined pipe releases the decomposition products of the lining. Pipe that has been in service may contain flammable or toxic residue. None of these are controlled by arrangements written for clean carbon steel. Occupational Hygiene · inherent risk 5C.
Ionising radiation causes tissue damage and increases cancer risk, with no sensation at the time of exposure. A gamma source that fails to retract into its shield can deliver a serious dose in a short time to anyone who approaches without a survey meter. Occupational Hygiene · inherent risk 5B.
Oxygen displacement causing collapse within seconds and death by asphyxiation, with no smell, no colour and no warning. Purge gas kills pipe fitters and welders in exactly this way, and the person who reaches in to help without breathing apparatus becomes the second casualty. Process Safety · inherent risk 5B.
Failure under pneumatic test releases the stored energy instantly, turning caps, blanks and fragments of pipe into projectiles that travel the length of a workshop. Pneumatic testing has killed people standing well clear of what looked like a safe distance. Process Safety · inherent risk 5B.
Welding fumes are classified IARC Group 1 (carcinogenic to humans, lung cancer, with limited evidence for kidney cancer). Also occupational asthma, chronic bronchitis and reduced lung function. The exposure standard for welding fumes (not otherwise classified) is 1 mg/m3 as an 8-hour time weighted average, and this figure carries through into the Workplace Exposure Limits that apply from 1 December 2026. Occupational Hygiene · inherent risk 4C.
Crush injuries, multiple fractures, fatality. Vehicle and mobile plant incidents are consistently among the leading mechanisms of work-related fatality in Australia. Safety · inherent risk 4C.
Load dropped onto a person: crush injuries, multiple fractures, fatality. Sling angle is the most common miscalculation, because working load limit falls sharply as the included angle opens up. Safety · inherent risk 4C.
Crush injuries to feet, legs and torso, and fatality. A rolling length of pipe cannot be stopped by hand and gathers speed on any slope, and the worker who steps in to stop it is the one injured. Safety · inherent risk 4C.
How one hazard is rated
Hazard S1.1 — manual handling of sections, plate and offcuts — starts at 2D, rated before any controls are counted. The calculator lists 8 controls for it, from elimination and extraction at the source down to PPE, monitoring and emergency arrangements. You answer Yes, No or N/A for each on the floor. Once the last one is answered it works out the control score, applies any severity reduction earned by physical controls, and shows the residual risk as RED, YELLOW or GREEN. Every control you answered No to goes into your Action Plan, most urgent and most effective first, ready for a responsible person and a due date.
Purge gas, positional fume and radiography in the spool shop
Spool shops serving petrochemical, power generation and commercial piping contractors cut and bevel pipe, fit and purge joints, run a TIG root and fill with MIG, flux-cored or stick, then dress, inspect and test. The quiet killer in this trade is argon back-purging. The gas is heavier than air, fills the bore and spills out of open ends at low level, and a fitter who reaches in to place or retrieve a dam, or looks into the bore, can collapse within seconds with no smell or warning.
Fume carries the long-term liability. Pipe welding goes all the way round the joint, so the welder's head passes directly over the plume and a fixed hood cannot follow. The facts record positional pipe welding as consistently producing the highest breathing zone concentrations of any bench welding, against a 1 mg/m3 welding fume standard and a manganese limit falling to 0.02 mg/m3 respirable from 1 December 2026. Spools also arrive as stainless, alloy, galvanised or lined pipe, bringing hexavalent chromium, nickel, zinc, lead or lining decomposition products if the material is not identified first.
Two hazards set this shop apart from general fabrication. Pneumatic pressure testing stores enough energy to turn caps and blanks into projectiles that cross a workshop, and industrial radiography of welds, often after hours with a gamma source or X-ray set, exposes people in adjacent bays to a dose they cannot feel.
The purge, the stack and the test bay
The assessment puts purging first. Personal oxygen monitors for everyone working on or near purged spools, fixed monitoring in pits and low bays, purge shut off with the spool ventilated and tested before anyone reaches or looks into the bore, and confined space entry for large-diameter spools and headers are all unconditional gates. Reaching into or looking into a purged spool without shutting off and testing is prohibited.
Pipe storage comes next, with chocks placed before any sling is released or any stack is disturbed as a gate. The assessment then asks how pressure tests are run: whether pneumatic testing is avoided in favour of hydrostatic, and whether blanks and temporary closures are rated for the test pressure. For radiography, it asks how exclusion zones are set and whether other trades are cleared from adjacent bays.
Routine plant checks cover emergency stops to AS/NZS 4024, grinder rests per AS/NZS 1788, and slings, shackles and hooks inspected against AS 3775, AS 4497 and AS 2741.
Typical first answers from a pipe shop
Spool shops usually have strong quality systems for weld procedures and inspection, and weak ones for the people doing them. Purge dams are set by hand with the argon running. Nobody wears an oxygen monitor because purging is routine. Pipe is stacked on bearers without chocks, and the fitter stands on the downhill side to guide a length off the rack. Radiography barriers are tape, and the night crew keeps working two bays away.
The controls that take these hazards to green are mostly about design. Hydrostatic rather than pneumatic testing, closures rated for the test pressure, pipe racks that stop lengths rolling, soluble purge film or dams placed before the gas is turned on, and extraction that can be repositioned around the joint rather than fixed above the bench.
NOT RATED is common on first pass in this trade. A fitter finishes the root on a large-diameter header, pulls the dam, and leans into the open end to check the root with a torch while the argon is still flowing. The prohibited practice is exactly that, and the purge hazard stays unrated until monitors are worn and the purge is shut off and tested before anyone looks into the bore.

This is a generic risk assessment for a typical workshop of this kind, to support your due diligence — completing it is not compliance in itself. You must answer it for your own site, consult your workers, put the missing controls in place, and get competent advice where it says so — exposure monitoring, for example, is work for an occupational hygienist. The limits are set out at the front of every report.
