COSHH Hazard Symbols | Quick Intro
If you are dealing with substances which may be hazardous to health, it would be useful to get familiar with the globally standardised hazard symbols.
Hazard pictograms alert us to the presence of a hazardous chemical or substance.
The hazard symbols help us to recognise that the chemicals we are using might cause harm to people or the environment.
When it comes to COSHH assessment, they help us to evaluate chemical compatibility and allow us to put suitable controls measures in place to protect people and property.
The CLP hazard pictograms are very similar to those used in the old labelling system and appear in the shape of a diamond with a distinctive red border and white background.
One or more pictograms might appear on the labelling of a single chemical.
Let’s take a look the 9 COSHH Hazard Symbols and what they mean for employee health and your business.

In the UK, COSHH stands for ‘Control of Substances Hazardous to Health’.
Under the Control of Substances Hazardous to Health Regulations 2002, employers need to either prevent or reduce their workers’ exposure to substances that are hazardous to their health.
COSHH Hazard Symbols | Some Reminders
In the UK, ‘COSHH’ is the law that requires employers to control substances that are hazardous to health. You can prevent or reduce workers exposure to hazardous substances by:
- finding out what the health hazards are;
- deciding how to prevent harm to health (risk assessment);
- providing control measures to reduce harm to health;
- making sure they are used ;
- keeping all control measures in good working order;
- providing information, instruction and training for employees and others;
- providing monitoring and health surveillance in appropriate cases;
- planning for emergencies.
Most businesses use substances, or products that are mixtures of substances. Some processes create substances.
These could cause harm to employees, contractors and other people.
Sometimes substances are easily recognised as harmful. Common substances such as paint, bleach or dust from natural materials may also be harmful.
In other circumstances, the potential harm caused by a substance or material may not be easily recognised or even understood.
