What Are Prohibition Signs?

Prohibition signs communicate actions or behaviours that are not permitted in a specific area. They use the universal ‘forbidden’ format: a red circle with a diagonal bar over a black symbol on a white background. Additionally, Australian workplaces recognise this design under AS/NZS 1319-1994.

Common examples include: No Smoking, No Entry, No Mobile Phones, No Alcohol, No Naked Flames, No Dogs, No Photography, No Pedestrians, and Authorised Personnel Only.

WHS legislation makes displaying prohibition signs a duty-of-care obligation. This applies wherever a behaviour poses a risk to health, safety, or security. Failure to display required signs can also result in WHS improvement notices and legal liability.

Frequently Asked Questions

What are prohibition signs and when are they required?

Prohibition signs communicate actions or behaviours that are not permitted in a specific area. Under AS/NZS 1319-1994, they use a red circle with a diagonal bar over a black symbol on a white background. They apply whenever a particular behaviour — smoking, using mobile phones, or unauthorised entry — poses a risk to health, safety, or security. Displaying prohibition signs is a WHS duty-of-care obligation in Australian workplaces. National Safety Signs supplies a full range of AS 1319 compliant prohibition signs for workplaces, construction sites, and public buildings across Australia.

What colour are prohibition signs in Australia?

Under AS/NZS 1319-1994, prohibition signs use a white background with a red circle and diagonal bar over a black symbol or text identifying the prohibited action. This red, black, and white colour scheme is mandatory under Australian WHS regulations. Workers and visitors recognise the prohibition instantly, regardless of language or prior safety training. The format separates prohibition signs from danger signs (red/black/white panel), warning signs (yellow/black), mandatory signs (blue/white), and emergency signs (green/white).

What is the most commonly purchased prohibition sign?

No Smoking signs are the most purchased prohibition sign in Australia. They are required in virtually every workplace, public building, vehicle, and outdoor recreation area under Commonwealth and state legislation. No Entry, No Mobile Phones, No Alcohol, and Authorised Personnel Only signs also rank among the highest-demand prohibition signs for workplaces and public facilities. National Safety Signs stocks all high-demand prohibition signs for same-day or next-business-day dispatch from our Brisbane facility.

Can I get custom prohibition signs with specific text?

Yes. National Safety Signs prints custom prohibition signs with your specific prohibited action or additional text, maintaining full AS/NZS 1319 compliance in colour, layout, and format. Custom signs suit situations where standard text does not precisely describe the prohibited action — for example, ‘No Forklift Entry — Pedestrian Zone’ or ‘No Photography — Privacy Area’. Submit requests via our online Design a Sign tool or contact our sales team for a quote.

Are no smoking signs mandatory in Australian workplaces?

Yes. No Smoking signs are mandatory in all Australian enclosed workplaces under the Work Health and Safety Act and state smoke-free legislation. This covers offices, factories, warehouses, construction site amenities, vehicles, and any enclosed public space.
