Hazchem Signs for Food Industry Compliance
Hazchem signs are mandatory for many Australian food facilities handling hazardous chemicals. They ensure safety, provide emergency responders with vital details, and help businesses comply with strict Australian regulations like the WHS Regulations and the Australian Dangerous Goods (ADG) Code. These signs display critical information, including Hazchem codes, UN numbers, and hazard class diamonds.
Key points:
- Purpose: Identify chemical hazards, reduce risks, and support emergency actions.
- Regulations: Compliance with WHS Regulations, ADG Code, GHS, and AS1216 is required.
- Common Uses: Cleaning agents (Class 8 corrosives), disinfectants (Class 3 flammables), and sanitisers (Class 5.1 oxidisers).
- Placement: Visible at entry points, storage areas, and on transport vehicles.
- Materials: Durable options like aluminium or vinyl ensure longevity in harsh environments.
Proper hazchem signage isn’t just about following the law – it’s about creating a safe workplace and protecting lives.
What Hazchem Signs Are and How They Work
Definition of Hazchem Signs
Hazchem signs are a specialised type of safety signage designed to communicate critical emergency information. Unlike general safety signs, these are tailored to provide technical details specifically for first responders and trained personnel during emergencies.
Each sign includes three key components:
- Hazchem Code: A code like ‘3YE’ that provides emergency response instructions.
- UN Number: A unique identifier, such as UN 1203 for petrol, used internationally to identify specific chemicals.
- Class Diamond: A visual symbol that highlights the primary hazard of the substance.
These signs are created to comply with standards like AS1216, the Australian Dangerous Goods (ADG) Code, and the Globally Harmonised System of Classification and Labelling of Chemicals (GHS). To ensure visibility, outer warning placards must display the word "HAZCHEM" in bold red uppercase letters, at least 100 mm high, on a white or silver background.
Such precise information is especially crucial in industries like food production, where managing chemicals with care is paramount.
Why the Food Industry Needs Hazchem Signs
Given their detailed design, hazchem signs play an essential role in food facilities. These environments often involve the use of hazardous substances such as corrosive, flammable, and oxidising chemicals. Without proper signage, these materials could cause burns, fires, or contamination. Clear hazchem signs help ensure these chemicals are stored and handled safely, safeguarding workers, maintaining food safety, and enabling swift action during emergencies.
"Hazchem signage is more than just a visual cue – it’s a legal, lifesaving and logistical necessity across Australian industries" [1].
Australian Hazchem Regulations and Standards
Australian Safety Standards for Hazchem Signs
In Australia, workplaces handling hazardous chemicals must follow strict regulations to ensure safety. The Work Health and Safety (WHS) Regulations serve as the legal backbone, requiring businesses to display hazchem placards if chemical quantities exceed specific "placard threshold quantities." This means not every food-related facility needs hazchem signs – only those storing chemicals beyond the set limits.
The Australian Dangerous Goods (ADG) Code provides technical guidance on the appearance of these signs. Standards like AS 1216 specify the design and placement of hazchem signage, while AS 1319 outlines the rules for general workplace safety signs. These standards work alongside the Globally Harmonised System (GHS), which standardises hazard pictograms and labelling for individual chemical containers. Together, these regulations form a robust safety framework, especially critical for facilities managing large chemical inventories.
These standards ensure that regulations are applied effectively in food and beverage workplaces.
How Regulations Apply to Food and Beverage Workplaces
Food and beverage facilities face unique challenges when it comes to complying with placarding requirements. Cleaning acids, flammable disinfectants, and sanitising oxidisers are commonly used in these settings, often in quantities that necessitate placards. Regular audits of chemical inventories against WHS threshold tables are essential to determine whether signage is required. If thresholds are exceeded, outer warning signs must be placed at all vehicle entry points, and bulk storage tanks need Emergency Information Panels displaying the UN number, hazchem code, and proper shipping name.
It’s important to differentiate between labelling and placarding. While GHS pictograms are suitable for individual chemical containers, they are not permitted for bulk storage or vehicle placarding under Australian law. In these cases, only ADG Code class labels are allowed. An exception to these rules applies to products intended for human consumption in domestic settings, such as 700 ml bottles of alcohol, which typically don’t require these specific labels [3]. However, the chemicals used in industrial food processing and cleaning rarely fall under such exemptions, making compliance a critical focus for the sector.
"A label is required for any substance, mixture or article classified as a hazardous chemical under Australian WHS Regulations." – Melissa Hampton, Dangerous Goods Storage Consultant, Storemasta [3]

Types of Hazchem Signs Used in Food Industry
Three Main Types of Hazchem Signs Used in Food Industry Facilities
Food facilities rely on three main types of hazchem signs to manage chemical risks effectively. Each type serves a specific purpose, helping to ensure safety and compliance within food production settings. Here’s a closer look at how these signs are used.
Class 8 Corrosive Signs for Cleaning Chemicals
Class 8 corrosive signs are used to identify strong acids and alkalis that can cause serious harm to skin and metal. In food processing areas, these signs are often placed near storage areas for substances like caustic soda, which is commonly used to clean equipment and floors. The sign includes a graphic showing corrosion on a hand and a metal surface, making its warning clear and easy to understand. These chemicals can pose significant risks if mishandled, so having proper signage in place is essential for maintaining worker safety.
Flammable Liquid Signs for Solvents and Disinfectants
Class 3 flammable liquid signs are marked by a flame symbol on a red background, indicating the presence of flammable substances. In the food industry, ethanol-based disinfectants are frequently used for cleaning and sanitation, while solvents like acetone are utilised in maintenance tasks. These substances are highly combustible and can ignite quickly when exposed to heat or sparks. Proper labelling is especially important in areas with electrical equipment or hot surfaces to minimise fire risks.
Oxidising Agent Signs for Sanitising Products
Class 5.1 oxidising agent signs feature a flame within a circle, signifying chemicals that can intensify combustion. Hydrogen peroxide, a common sanitiser for food contact surfaces and packaging, falls under this category. While not flammable on its own, it can accelerate fires when combined with combustible materials. Clear signage and careful storage practices are key to preventing dangerous reactions.
All these signs must adhere to Australian Standard AS1216 and the ADG Code, with standard dimensions of 270 mm × 270 mm. This consistency in size and design ensures quick recognition of hazards in storage and transport areas, supporting both safety and regulatory compliance.

Where and How to Display Hazchem Signs
Recommended Locations for Sign Placement
Placing hazchem signs in the right spots is essential for meeting safety regulations and ensuring emergency responders can act quickly. Outer warning signs should be installed at every vehicle entrance to facilities storing dangerous goods above the threshold quantity – this includes all gates, not just the main entrance [2][1]. This placement ensures emergency services can identify risks no matter which access point they use.
For bulk storage areas, such as tanks, vats, or silos, signs should be mounted directly on the containers or positioned nearby [2][1]. When it comes to packaged goods and intermediate bulk containers (IBCs), signs should be displayed at the entrances of the specific buildings or rooms where these materials are stored [2]. If your facility operates its own distribution, transport vehicles must have three signs: one on the front, one on the rear, and one on the side [2].
Visibility is critical. Signs must remain unobstructed, meaning they shouldn’t be hidden by parked vehicles, equipment, or open doors [2]. Avoid placing signs on doors that, when opened, block the warning information [2]. Signs should also be installed at a height that ensures they are easy to see and read [2].
Making Signs Visible and Long-Lasting
Once you’ve chosen the right locations, it’s important to focus on durability and maintenance to keep your signs effective over time. The material you choose plays a big role in how well your signs hold up. For permanent facility installations, rigid aluminium panels are ideal, while self-adhesive vinyl works well for direct application on containers [2]. Aluminium composite panels and outdoor laminates are particularly durable, offering resistance to fading and damage for up to five years [2].
Regular maintenance is key. Clean your signs to remove dirt and ensure landscaping, like overgrown bushes, doesn’t block them [2]. If your chemical inventory changes, update the signage immediately to reflect the correct hazchem codes and UN numbers, ensuring emergency services have accurate information [2]. Regular checks are also essential to ensure signs aren’t hidden by vehicles, pallets, or other obstructions [2].
