Hazard Symbols And Their Meanings
Do your employees handle hazardous substances or chemicals in the workplace?
If the answer is yes, then they must be aware of the COSHH (Control of Substances Hazardous to Health) hazard symbols and meanings.
COSHH hazard symbols help to maintain health and safety in the workplace as they identify substances that are harmful and reduces the associated health risks.
In 2015, the original orange and black COSHH hazard warning symbols were replaced with ‘harmonised’ classifications.
The new red and white hazard warning signs are more accurate and more easily identifiable.
The updated COSHH hazard symbols allow some room for interpretation, although they should give you a good indication of the main hazards associated with a particular substance.
Below, we are going to discuss the nine COSHH symbols and the hazard symbols meaning:
The COSHH hazard sign is the picogram of an exploding bomb.
The Health and Safety Executive (HSE) advises that flammable materials should be stored in suitable cabinets of fire-resisting construction.
Examples of flammable substances include flammable gas, flammable aerosols, and flammable liquids. The hazard sign for flammable substances is the above picogram of a flame.
Oxidising materials are considered hazardous because they pose a serious fire and explosion risk.
Examples of oxidising substances include hydrogen peroxide solutions, bromine and aluminium nitrate. The COSHH hazard sign is a flame over a circle.
Destructive substances that react and destroy human tissue on contact. Corrosive materials may also damage or destroy durable materials like metal.
Corrosive substances must be handled using the appropriate PPE and stored in a secure location.
Examples of corrosive materials include strong acids like sulphuric acid and hydrofluoric acid. The corrosive hazard sign shows corrosion of material and skin.
Most toxic substances can be fatal if ingested, inhaled, or absorbed by the skin – which is why these materials require hazard warning signs.
Examples of toxic materials include carbon monoxide, chlorine and hydrogen sulphide. The toxic hazard sign is a skull and crossbones.
Exposure to these materials should be avoided or minimised to reduce the associated health risks. The COSHH hazard sign is the picogram showing an exclamation mark.
Serious health hazard
This includes materials that can damage internal organs if swallowed or substances that can damage fertility or cause genetic defects. The new COSHH hazard sign shows a person with internal damage.
Asbestos removal experts

Dangerous for the environment

Hazard warning symbols must also be displayed on substances that can cause environmental harm.
Examples of substances that are dangerous for the environment include pesticides, petrol and biocides. The new COSHH hazard sign shows a dead tree and fish.
Gases under pressure
Pressured containers need to be checked regularly for damage or leakage and must be stored away from heat and ignition.
The COSHH hazard sign is the picogram above showing a gas cylinder.
