Hazard safety signs play an essential role in the management of your safety, warning your staff and visitors of any potential dangers on the premises.
Hazard signs have a yellow triangle with a black pictogram or symbol on a yellow background with a black border. The yellow part has to be at least 50% of the area of the sign. Many of the hazard symbols currently used have been updated to bring them in line with the new ISO 7010 legislation.
The three different types of hazard signs
There are typically three different types of Hazard sign:
Each sign is categorised as the above depending on the severity of the risk. For example, signs with the word “Danger” are used where the risk is deemed to be higher than those signs using the word caution.
What do Danger Signs mean?
These are used for a high level of risk which, if not avoided, may result in death or serious injury.
They are typically only used in situations that have a high probability of death or severe injury. Danger signs should not be used for situations covering potential property damage unless personal injury risk is present.
Examples of Danger Signs

Warning signs should be used for a medium level risk. Medium-level risk signs are signs that if not avoided, may result in injury or death.
Warning signs should be used in hazardous situations which have some probability of death or major injury.
Warning signs should not be used for situations covering potential property damage unless personal injury risk is a possibility.
