Protect Your Team with Prohibition Signage

Prohibition Signs are critical safety tools used to communicate behaviours that are not allowed. They usually feature a universally recognised design—a red circle with a diagonal line through a black pictogram on a white background—which ensures their message is clear and immediate. Whether instructing people not to smoke, enter or use mobile phones, these signs help eliminate ambiguity in environments where safety is paramount.

In Australian workplaces, especially those governed by strict WHS regulations, Prohibition Signage plays a vital role in reducing risks and preventing accidents. By clearly indicating what actions are forbidden, they not only help protect workers and visitors but also safeguard businesses from non-compliance penalties. From construction sites and manufacturing plants to schools and retail spaces, Prohibition Signs are essential for upholding safety standards, enhancing clarity and promoting a culture of responsibility.

Australian-Made Prohibition Signs for Safer Sites

In high-risk environments or any place where clarity and compliance are critical, Prohibition Signs are a legal and ethical must-have. At New Signs, we understand how vital it is to maintain a safe and rule-abiding environment—one where expectations are clear, hazards are minimised and every person knows exactly what not to do, the moment they see the sign.

What Are Prohibition Signs?

A Prohibition Sign is used to instruct people not to do something. Easily recognised by their iconic red circle with a diagonal line through the action, they are a universal language for “Do Not.” These signs don’t just protect people; they safeguard businesses from liability and disruption. Prohibition Signage is essential for reducing risk, avoiding fines and ensuring your workplace complies with the Work Health and Safety (WHS) Act in Australia.

Built for Australian Conditions

New Signs’ range of Prohibition Signs is made right here in Australia. Our signs are weatherproof, UV-stable, and suitable for both indoor and outdoor use. Choose from a wide variety of sizes and materials, including lightweight Corflute for temporary use or Aluminium Composite Panel (ACP) for more permanent installations.

Whether you need a “No Smoking” sign for a warehouse, a “No Entry” decal for a restricted area, or a “No Mobile Phones” sign for a construction site, you’ll find the right solution in our extensive collection. We even offer custom options to suit unique site requirements.

Easy to Understand

Clear, concise text paired with universally recognised iconography ensures that the message is immediately understood—regardless of a person’s language, reading ability or familiarity with the site. This instant recognition is especially critical in emergency or high-risk situations, where every second counts and misinterpretation can lead to serious consequences. Prohibition Signs remove ambiguity and reinforce safety protocols with a simple glance.
