Each state of Australia has its own governing agency that oversees gas safety. Western Australia’s governing agency is Energy Safety WA. They set legal standards related to the use of gas appliances indoors, outdoors, and in semi-enclosed spaces such as alfresco areas. These legal standards must be adhered to.

Using gas appliances in enclosed spaces can be lethal if the gas appliances are not designed for indoor use. The main risks are gas inhalation, oxygen deprivation and fire.

It is vital that you understand if your Alfresco area is classed as enclosed or outdoors.

Is My Alfresco Area Enclosed?

Your alfresco is NOT considered to be enclosed, and would therefore be classified as an outdoor area, only where;

  • The area has walls on all sides but at least one permanent opening at ground level and no overhead cover.
  • The area has a partial enclosure that includes an overhead cover and no more than two walls
  • The area is partially enclosed including an overhead cover and three or more walls with at least 25% of the total wall area completely open AND at least 30% of the remaining wall area is open and unrestricted.
  • Balconies must have at least 20% of the total wall area open and unrestricted

If your alfresco area is more enclosed than the above diagrams, then it is classified as indoors.

Energy Safety WAs requirements for indoor alfresco areas are as follows:

  • BBQ must have flame failure devices fitted to every burner and be licensed for indoor use (Please be aware that not all BBQs with a flame failure device are also licensed for indoor use)
  • BBQ must have a commercial grade exhaust hood that moves a minimum of 2000 cubic metres of air per hour
  • BBQ must be installed on a non-combustible surface

Outdoor Alfresco Kitchens manufacture barbeques, exhaust hoods and cabinets which comply with these laws.
