Medical gases

Medical gas means a substance used for medical purposes and prescribed by the regulations as a medical gas.

  • Air at a negative pressure
  • Oxygen
  • Nitrous oxide
  • Helium
  • Nitrogen
  • Cardon dioxide
  • Medical air
  • Surgical tool gas
  • Common mixtures of the gases referred to in paragraphs (a) to (g) and
  • Waste anaesthetic gas
  • Air at negative pressure
  • Medical tool

Licence types

Medical gas systems work is specialist work.

There are different types of licences available in NSW depending on if you want to contract for another party or supervise work.

Contractor licence

From 1 July 2020, you can apply for a 1, 3 or 5 year contractor licence.

A contractor licence allows you to contract and advertise to do work. You can only do the types of work described on your licence card.

Contractor licences can be issued to individuals and to companies and partnerships.

Qualified supervisor certificate

From 1 July 2020, you can apply to have a qualified supervisor certificate issued for 1, 3 or 5 years.

A qualified supervisor certificate allows you to supervise and do the work described on your certificate. Qualified supervisor certificates are only issued to individuals. A qualified supervisor certificate doesn't allow you to contract for work.

An endorsed contractor licence is issued to individuals who apply for a contractor licence and who also have the qualifications and experience needed to be a qualified supervisor. Endorsed contractor licence cards have ‘contractor licence (Q)’ printed on them to show they are equivalent to a Qualified Supervisor Certificate.

Tradesperson certificate

Certificates are issued for 1,3 or 5 years. Tradesperson certificates used to be known as a ‘journeyman’.

A tradesperson certificate allows you to do medical gas fitting work with minimum supervision.

Individuals who hold a tradesperson certificate can't sign off on work. Any work must be overseen and signed off by someone who holds a contractor licence or qualified supervisor certificate. Tradesperson certificates are only issued to individuals.

Tradesperson certificates can only be issued for installing medical gas pipeline systems.
