Mobile Welfare Units for Australian Worksites

Under Australian WHS legislation, most commercial and civil worksites are legally required to provide workers with toilet facilities, shelter for breaks, drinking water, and hand-washing. A Scanvogn welfare unit satisfies all of these obligations in a single ADR-registered, road-towable trailer.

What is a Welfare Unit?

A welfare unit is a self-contained portable facility providing workers with WHS-compliant toilet access, a rest area, kitchen facilities, and potable water. Scanvogn welfare units are ADR-registered, road-towable, and built to Australian standards. All Scanvogn trailers sold in Australia are ADR-registered and can be towed with a standard Australian car licence on units under 4,500kg GTM.

What the WHS Regulations Actually Require

Under the Safe Work Australia Code of Practice for Construction Work, employers must provide workers with access to:

A single Scanvogn welfare unit typically satisfies all five requirements in one road-registered trailer. Set it up on Monday — be inspector-ready by Tuesday.

Scanvogn Welfare Unit Range

Choose from purpose-built models across four product lines. Each unit is ADR registered, insulated for Australian conditions, and towable with your existing vehicle.

Staff Cabin Trailer

Office, kitchen, shower, toilet and locker room in one trailer. Suits 4–15 workers. Ideal for long-term civil and construction projects where crew need full welfare facilities on site.

Pioneer Cabin — Off-Grid

Solar, LPG and water tanks built in. No mains connection required. Rated for remote sites — mining, forestry, and infrastructure in areas without grid power or water services.

Office Trailer with Toilet

7 lengths from 3.2m to 9.0m. Optional integrated toilet means no separate welfare unit needed. Suits project managers who need a desk and compliant facilities in one trailer.

Environment Cabin

Separate decontamination zone for hazardous worksites — oil, asbestos, epoxy. Zone 1 for dirty clothes and shower. Zone 2 for clean living area and toilet facilities.

Frequently Asked Questions

What does a mobile welfare unit provide to meet WHS rules?
One unit provides the facilities the Safe Work Australia Code of Practice expects: toilets, shelter and seating for breaks, potable drinking water, hand washing, and changing facilities for hazardous work — all in a single road-towable trailer.
How many workers does one welfare unit service?
Depending on model: an office trailer with toilet suits 4-12, a staff cabin up to 15, a pioneer cabin (off-grid) up to 10, and an environment cabin up to 10 with a decontamination zone. Customised units serve 30+.
How many toilets do WHS rules require on a construction site?
The Safe Work Australia Code of Practice guides one toilet per 15 workers on sites operating under three months. A single Scanvogn welfare unit typically satisfies this along with the other welfare requirements.
Can a welfare unit work on a site with no power or water?
Yes. The Pioneer Cabin has solar, LPG and onboard tanks built in for fully off-grid operation, and tank or incinerator toilet options mean no sewer connection is needed.
