These chemicals will eat away at a wide range of materials and surfaces. They corrode, dissolve and even melt the materials they come into contact with.

These substances require very careful handling and specific storage methods and procedures in order to ensure they don’t catch alight.

This subclass contains all oxidising agents, with the exception of organic peroxides (more on that below), and are represented by a solid yellow diamond with a unique pictogram.

HazchemCode List

Each of these substances poses a risk to health and wellbeing – however, they also don’t neatly fit into any of the other categories.

As such, these substances need to be handled with extreme caution. Staff need to wear protective equipment, and require special containers.

Australia uses a system of labelling for dangerous goods based on globally-recognised standards. This system helps you to immediately recognise:

Depending on the substance, it could be fire that makes them explode – in others, it could be an electrical current. Each one is different – be sure to identify the potential causes with emergency information panels and a proper dangerous class custom sign.

Take it from us: staying safe around hazardous chemicals and substances is much more complicated than just sticking up a hazchem sign and calling it a day!

While modern explosives are stable and safe to handle by trained professionals, not all explosives are so stable, especially when tampered with or handled improperly.

These organic peroxides are represented by a diamond with a red top and a yellow bottom. Picture a beach safety flag with the standard fire pictogram on it, and you have the right idea!

In addition to supplying hazchem diamonds, our team also helps improve compliance with Australian regulations as well as your OHS requirements.

Dangerous and hazardous goods are placed into categories based on the hazards they pose. In Australia in particular, there are 9 broad categories of dangerous and hazardous goods, with several subsections where needed.

It isn’t just open flames that can cause these solids to combust – some can become reactive when they come into contact with oxygen, and in some cases, even water!

As such, each of these solids has its own dangerous goods class sign. Each uses the globally-recognised fire pictogram – however, the colours and text change depending on the subclass.

In particular, it’s important that any areas where you store chemicals and other hazardous goods are identified with dangerous goods class sign.

Certain solids like calcium, sodium and magnesium can create a chemical reaction when exposed to water or moisture. Not only can moisture from the air cause a fire, but you may actually make the problem worse by using water or foam to extinguish them.

And just like flammable gas (class 2.1), flammable liquids are represented by a red diamond with a fire pictogram. The only difference is the number and the text on the sign.

Hazchem and dangerous goods class labels are an important part of keeping your workplace safe – especially if you regularly deal with hazardous and dangerous substances and goods.

While there are 3 distinct subclasses of poisonous and infectious substances, we’ll be focusing on class 6.1a: toxic substances.

Hazchemclassification

Like the name suggests, these are liable to cause death or serious injury to human health if inhaled, swallowed or absorbed through the skin. As such, they need to be treated with care, and often have special regulations regarding proper handling.

To differentiate these from flammable gases and liquids, these dangerous goods class signs use red and white vertical stripes instead of a solid red background.

So it’s little wonder that this is one of the most common hazchem class signs we sell here at Signsmart; petroleum companies like Caltex are some of our biggest clients.

HazchemCode examples

Flammable liquids are without a doubt the most common type of hazardous chemical on Australian roads – after all, 81% of Australian cars run on petrol.

What’s more, if a sign demonstrates multiple of these attributes, it will also need several class diamonds – one for each class it falls under.

When it comes to flammable solids, class 4.1 refers specifically to solids that need direct exposure to a naked flame or extreme heat to ignite. Some examples include:

Thanks to their unique properties, extra precautions should be taken. In particular, we suggest getting in touch with your signage company for custom signage to ensure that your staff know how to react safely.

That’s because these gases are often stored under significant pressure, and thus contain considerable amounts of stored energy. A leak or puncture can result in the container flying around – just picture a balloon being let go!

As we’ve mentioned before, there’s a whole bevy of different legal requirements that come with storing and using hazardous chemicals and materials, one of which is using appropriate hazchem signage.

These are just some of the more common examples. Others include industrial chemicals, as well as pest control poisons. All substances that fall under this umbrella are identified by a white dangerous goods class label with a skull on it.

These categories are then identified using hazchem class diamonds, with each class having its own unique colour, icon and number.

The hazchem diamond for radioactive materials features the well-known trefoil symbol on a yellow background, signalling the presence of radiation.

Radioactive materials emit harmful radiation, which can cause serious injury or even death if not handled properly. They can also cause serious health issues like radiation sickness, cellular damage, and increased cancer risk.

Of course, it isn’t as simple as just picking out a sign – when it comes to hazchem class diamonds, it’s important that you choose a sign that matches the hazchem class.

Miscellaneous hazardous and dangerous goods class labels don’t have a pictogram – there are just too many that fall into this category. Instead, they’re simply represented by a diamond with a white bottom half, and a black-and-white striped top half.

Pool chemicals, peroxides, nitrates… each of these can greatly increase the risk of combustion of other chemicals or materials.

Typically non-flammable and non-toxic, gases like aerosols, nitrogen and compressed air are nonetheless still potentially dangerous.

Oxidising chemicals aren’t necessarily flammable in themselves – however, they can easily contribute to a fire, thus necessitating their own hazchem class signs.

In cases where shipments contain mixed substances or different substances are stored in the same area, you may even need multiple class signs.

These solids are the most dangerous to transport, owing to their volatility. Specifically, these solids can combust when exposed to oxygen!

These substances have their own class diamonds, featuring two pictograms: one of a hand being splashed with acid, and one of a surface being corroded, with a white top and a black bottom.

These substances can cause immediate and oftentimes serious harm to the human body. In many cases, the fumes they emit are also dangerous if inhaled.

Specifically, these refer to chemicals and substances that give off oxygen, which can fuel fires. It also includes substances that react with materials in such a way that their presence dramatically increases the chance of a fire or explosion.

That can include fabrics, tables, flooring and containers that aren’t made of suitable materials. Some are even strong enough to corrode metal!
