Steam and condensate piping covers the installation and maintenance of steam and condensate-return pipework in industrial and commercial settings — the high-temperature, high-pressure pipework that distributes steam and returns condensate for process and heating systems. It is high-hazard pipework: steam is at high temperature and pressure and causes severe scalding and burns, a steam release can be catastrophic, the pipework and condensate are extremely hot, and the system holds significant stored energy. This document is written on the basis that steam and condensate piping is carried out by competent personnel with the steam, high-temperature, pressure and stored-energy hazards rigorously controlled.
Steam and condensate piping is carried out in connection with the relevant pressure piping and pressure equipment standards, with the system isolated, depressurised and cooled before work, because steam at temperature and pressure causes severe injury. The hot pipework, the high pressure, the stored energy and the consequences of a steam release are the defining hazards. This document coordinates the steam, high-temperature, pressure, isolation and stored-energy controls so the steam and condensate pipework is worked on safely.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Engineering: isolate, depressurise and cool the steam and condensate system before the work, confirming it is isolated and at a safe temperature and pressure, because steam at temperature and pressure causes severe injury.
- 2Engineering: install and maintain the steam and condensate pipework to the relevant pressure piping and pressure equipment standards, managing water hammer and condensate.
- 3PPE: protection against the hot pipework, steam and condensate, including appropriate gloves and protective clothing, in addition to the standard PPE.
- 4Administrative: manage the stored energy and pressure of the steam system throughout, and never work on a live, pressurised or hot steam system without isolation and making safe.
- 5Administrative: where hot work is carried out, apply the hot-work precautions — permit, fire watch, clearing combustibles and extinguishing means.
- 6Administrative: manage heat illness in the hot plant environment, and apply the confined space controls in enclosed plant spaces.
- 7Engineering: use mechanical aids for the heavy pipework and equipment, and pressure test and commission the system before it is returned to service.
- 8Administrative: ensure the work is carried out and certified by an appropriately licensed plumber, drainer or gasfitter under the relevant state or territory plumbing and gasfitting licensing scheme, with the relevant competencies and a compliance certificate issued where required.
- 9Administrative: all workers must hold a valid White Card (General Construction Induction Training, CPCCWHS1001) where the work is construction work, with the plumbing, gasfitting, confined space and any other competencies required for the work.
- 10Administrative: conduct a pre-start toolbox talk covering the day's work, identified hazards, isolations, required PPE and emergency procedures, and record attendance in the consultation section.
- 11Administrative: consult workers and any health and safety representatives on the work and its risks, record the consultation, and keep this document available at the workplace.
- 12PPE: eye protection to AS/NZS 1337.1, hearing protection where required, gloves appropriate to the task, high-visibility clothing, and Class I or Class II safety footwear with protective toecap to AS/NZS 2210.3.
- 13Administrative: review and update this SWMS whenever the work scope changes, after any incident or near miss, when a worker or health and safety representative raises a concern, when new hazards are identified, or at minimum every 12 months.

Worked example
A competent pipefitter is engaged to install and modify steam and condensate pipework in an industrial plant. The steam and condensate system is isolated, depressurised and cooled before the work, confirmed isolated and at a safe temperature and pressure, because steam at temperature and pressure causes severe injury. The pipework is installed and maintained to the relevant pressure piping and pressure equipment standards, managing water hammer and condensate. Protection against the hot pipework, steam and condensate is worn. The stored energy and pressure of the system are managed throughout, and the system is never worked on live, pressurised or hot without isolation and making safe. Hot work is carried out under a permit with a fire watch and extinguishing means. Heat illness in the hot plant environment is managed, and confined space controls applied in enclosed plant spaces. Mechanical aids are used for the heavy pipework. The system is pressure tested and commissioned before return to service, and the records retained.

Frequently asked questions
Why is steam piping so hazardous?
Steam is at high temperature and pressure, so a steam release causes severe scalding and burns that can be fatal, and the system holds significant stored energy that can release catastrophically. The pipework and condensate are extremely hot, so the system is isolated, depressurised and cooled before work, and never worked on live.
How is the steam system made safe before work?
The steam and condensate system is isolated, depressurised and cooled before the work, confirmed isolated and at a safe temperature and pressure. Making the system safe — isolating, depressurising and cooling — before any work is the defining control, because steam at temperature and pressure causes severe injury.
What is water hammer in a steam system?
Water hammer is a pressure surge that occurs when condensate is driven through the system or when steam meets condensate, which can damage the pipework and cause a hazard. The pipework is installed and maintained to manage water hammer and condensate, controlling this hazard of steam and condensate systems.
What hot-work controls apply?
Where hot work — welding or cutting — is carried out on the steam pipework, hot-work precautions apply: a permit, a fire watch, clearing combustibles and extinguishing means, to AS 1674.1. The hot-work controls manage the fire and burn hazard, in addition to the steam isolation and making-safe controls.
Who works on steam and condensate piping?
Steam and condensate piping is carried out by competent personnel in connection with the relevant pressure piping and pressure equipment standards, because of the high-temperature, high-pressure and stored-energy hazards. The work is carried out with the system isolated and made safe, and pressure tested and commissioned before return to service.
