If you are working with chemicals that are hazardous to health, or completing COSHH risk assessments, you should be aware of the symbols that are included on the packaging of substances, and what they mean. These symbols give you a good indication of the main hazards associated with the substance.
Ever seen those square orange symbols on bottles and tins like paint and cleaning substances, and wondered what they mean? Or you might already be familiar with new diamond black and red COSHH symbols, that replaced the orange symbols in 2017. Or that might just have added to the confusion!
The square orange and black COSHH symbols that have been around for years under the Chemicals (Hazard Information and Packaging for Supply) Regulations - known as CHIP.
The diamond red and black COSHH symbols are newer and were introduced by the European Regulation on the classification, labelling and packaging of substances and mixtures (known as the CLP Regulations ). They have been gradually phased in since 2009.
What do both groups of symbols have in common? Orange or red. Square or diamond. They are hazard symbols given to chemicals and substances that are hazardous to health. Both CHIP and the CLP Regulations ensure that the hazards are clearly communicated to workers and consumers. On packaging, labelling and datasheets.
Both sets of COSHH symbols were around together for a while. However, the orange symbols have been gradually phased out over the last decade. The red diamond symbols officially replaced the orange symbols on the 1st of June 2017. The new diamond red and black symbols are what you now need to know about, and we are going to cover them in this post.
Gases under pressure
Serious health hazards
Dangerous for the environment
These names are not the official names given to each symbol. In fact, the regulations actually give each symbol to a range of meanings. So some categories might be known by a couple of names, for example, health hazard is sometimes referred to as 'caution'. And serious health hazards is also known as long-term health hazards. Some are fairly self-explanatory, but some are a little more confusing.
While there are 9 COSHH symbols officially in use today (the current red and black ones), the orange pictograms might still be present in older stock and past material safety data sheets (MSDS). So really, there are 18 COSHH symbols, and we will look at which orange symbols have been replaced (and removed).
It's not just the colour of the COSHH symbols that changed. New meanings were introduced, and some symbols were phased out. If you want to know what changed since the old square orange and black symbols, we will look at that too.
Placed on the packaging of hazardous substances, COSHH symbols are there to tell you about the type of hazard a substance presents. A substance may be classified as one or more of the following 9 types:
These are chemicals and preparations that explode. This is a straight replacement for the previous explosive classification. The symbol is a pictogram of an exploding bomb.
Chemicals that may catch fire in contact with air, only need brief contact with an ignition source, have a very low flash point or evolve highly flammable gases in contact with water. It replaces the old classifications of highly flammable and extremely flammable. The symbol is a flame.
A classification for chemicals and preparations that react exothermically with other chemicals. Replaces the previous symbol for oxidising. The symbol is a flame over a circle.
Gas stored under pressure, such as in gas containers. This is a new symbol that wasn't represented under the old classification system. The symbol is a gas cylinder.
Chemicals that may destroy living tissue on contact. Matches the previous symbol for corrosion, the pictogram shows corrosion of material and skin.
Chemicals that at low and very low levels cause damage to health. Replacing the old classifications of toxic and very toxic. The symbol is a skull and crossbones.
Chemicals that may cause damage to health. Also known to mean caution. This is the closest replacement to the previous harmful and irritant classifications. The symbol is an exclamation mark.
Also known to mean long term health hazards. These are chemicals that can cause serious and long term damage to health. The symbol shows a person with damage.
Chemicals that may present an immediate or delayed danger to one or more components of the environment. The symbol is of a dead tree and fish.

Since COSHH assessments are a legal requirement , if you are working with chemicals that are hazardous to health, and completing the necessary COSHH risk assessments, you should be aware of these symbols. They are included on the packaging of substances to guide you as to the type of hazard it is. These COSHH symbols give you a good indication of the main dangers and risks associated with the substance.
Once you have identified the type of hazardous substance used, you can start assessing the risks to those using the substance. This will help you to pick the safety measures you need to minimise those risks to a safe level.
