Understanding the 6 Categories of Workplace Safety Signage in Australia
Apr 15, 2025
Safety signage plays a critical role in every workplace. Whether it’s a construction site, factory floor, warehouse, office, or retail space, clear and effective signage helps prevent accidents, protects employees and visitors, and ensures compliance with Australian workplace safety standards.
In Australia, the use and design of workplace safety signs are governed by AS 1319:1994 – Safety Signs for the Occupational Environment. This Australian Standard outlines how signs should be used to warn of hazards, provide instructions, and guide safe behaviour. It works alongside the Model Work Health and Safety (WHS) Regulations developed by Safe Work Australia, which require businesses to manage risks and maintain a safe working environment.
Let’s explore the six main categories of workplace safety signage recognised under AS 1319, what each one means, and how to use them correctly.
Regulatory Signs
Regulatory signs indicate instructions that must be followed. These signs are used to communicate rules that apply to a specific area or task. There are two main subcategories:
- Prohibition signs, which tell people what they must not do.
- Mandatory signs, which tell people what they must do.
Prohibition signs have a red circle with a diagonal line through it. The image behind the line shows the prohibited action — for example, a cigarette for “No Smoking”.
Mandatory signs use a blue circle with a white symbol or text indicating the required action — for example, wearing safety goggles or hearing protection.
Examples include:
- “No Entry”
- “Do Not Operate”
- “Hearing Protection Must Be Worn”
These signs help enforce safe behaviour and ensure everyone understands their responsibilities on site.
Warning Signs
Warning signs are used to alert people to potential hazards that could result in minor or moderate injury. These hazards are not usually life-threatening but still pose significant risk.
These signs feature a yellow background with black text and symbols, often in the shape of a triangle.
Examples include:
- “Slippery When Wet”
- “Forklifts in Use”
- “Low Headroom”
Placing these signs in the right locations helps prevent accidents by making workers more aware of their surroundings.
Danger Signs
Danger signs indicate immediate or life-threatening hazards. These are used in high-risk areas where failure to comply could lead to serious injury or death.
These signs are easily recognisable with the word DANGER in white on a red oval with a black background.
Examples include:
- “High Voltage”
- “Confined Space – Permit Required”
- “Explosive Atmosphere”
Under WHS laws, employers must ensure these signs are clearly visible wherever high-risk hazards exist. It’s also important to provide proper training on how to safely navigate or avoid these hazards.
Emergency Information Signs
Emergency information signs provide clear directions to emergency-related equipment and facilities. These signs help people respond quickly and calmly in the event of an emergency.
They are typically green with white text or symbols.
Examples include:
- “First Aid Station”
- “Emergency Exit”
- “Emergency Assembly Point”
These signs must be strategically placed and free from obstructions to ensure they’re visible and accessible during an emergency.
Fire Signs
Fire signs indicate the location of fire-fighting equipment. While they don’t provide instructions on how to use the equipment, they guide people to where it is stored.
These signs have a red background with white text or pictograms.
Examples include:
- “Fire Extinguisher”
- “Fire Hose Reel”
- “Fire Blanket”
Under AS 1319 and WHS guidelines, all fire equipment should be properly labelled and regularly maintained. Clear signage supports fast action in the event of a fire.
General Information Signs
General information signs are used for non-hazard-related messages that support safety or operational efficiency. These are not formally standardised like the others but are still useful in many work environments.
They typically have a white background with black text and may include symbols or pictograms.
Examples include:
- “Office”
- “Deliveries at Rear”
- “Lunchroom”
Although not legally required under AS 1319, these signs can improve navigation and reduce confusion, especially in larger workplaces or shared facilities.
Why Workplace Safety Signage Matters
Workplace signage is more than just a compliance box to tick. It plays a critical role in:
- Preventing accidents and injuries
- Communicating risks and responsibilities
- Helping staff and visitors respond quickly in emergencies
- Supporting overall workplace safety culture
According to Safe Work Australia, clear and visible signage should be part of a broader risk management strategy. Employers have a duty to provide and maintain a safe workplace under the Model WHS Act. This includes identifying hazards, assessing risks, and implementing control measures — including appropriate signage.
Staying Compliant with AS 1319 and WHS Guidelines
To stay compliant, workplaces should:
- Use signage in accordance with AS 1319:1994
- Conduct regular safety audits to ensure signs are visible, legible, and up to date
- Remove outdated or irrelevant signs to avoid confusion
- Train employees to understand the meaning and importance of each sign type
You can also refer to Safe Work Australia’s Code of Practice for managing risks, which outlines when signage is required and how it should be used.
Workplace safety signs are a simple but powerful tool for protecting workers, meeting legal obligations, and promoting a culture of safety. By understanding the six main categories — Regulatory, Warning, Danger, Emergency, Fire, and General Information — and following AS 1319 and WHS guidelines, businesses can ensure they are doing their part to create safer, more compliant workplaces.
If your site’s signage needs a refresh or you’re unsure whether you’re meeting the current standards, consider conducting a signage audit. It’s a small step that can make a big difference in keeping everyone safe.
