The 5 types of health and safety signs are:

Every type of health and safety looks different. Through shape and colour combinations, they can send their message through just a picture or icon. Once you know what you are looking for, you can quickly understand the exact meaning of the sign (even without reading the words).
Here are the 5 health and safety signs and their meanings.
Prohibition Signs
Prohibitions signs are there to tell you not to do something. They are a danger sign, telling you that it is not safe to proceed. And what colour makes you think of danger? Red of course! These signs have a red circle with a red diagonal line through it. The pictogram is black on a white background.
An easy way to remember the shape of prohibition signs is that is a circle, like a full stop. And the sign literally means, stop.
Colour: Red
Shape: Circle
Meaning: Do not, Never, Stop, No
Examples:
- No unauthorised persons
- No entry
- No smoking
- Do not operate
- No parking
Mandatory Signs
Mandatory signs are there to tell you to do something. Consider these the opposite of prohibition signs. These signs are round in shape. The pictogram is white on a blue background. The circle usually has a white border.
Instead of being round for full stop (like prohibition signs), you can remember that mandatory signs are round for ‘Obey’. Because that is what you must do, obey them.
Colour: Blue
Shape: Circle
Meaning: Do this, You must, Obey
Examples:
- Wear a face mask
- Ear protection must be worn
- Keep fire door closed
- Keep clear
- Pedestrians only
Warning Signs
Warning signs are there to warn you of dangers. Unlike the two previous signs, they don’t tell you not to do something, or to do something. They simply aim to make you aware of a danger, so you can protect yourself.
These signs are triangular in shape. The pictogram is black on a yellow background, the triangle has a black border.
Colour: Yellow
Shape: Triangle
Meaning: Warning, Be careful, Be aware
Examples:
- Caution hot water
- Danger 440 volts
- Mind the step
- Fragile roof
- Caution slippery floor
Safe Condition Signs
Safe condition signs can usually be followed to safety. And what colour better represents safety than green? That’s right, they are green!
These signs are rectangular or square in share. The pictogram is white on a green background, and will often have a white border.
Colour: Green
Shape: Rectangle
Meaning: Follow, This way, Escape route, First aid
Examples:
- Fire exit
- Push bar to open
- Assembly point
- First aid box
- Emergency stop
Fire Equipment Signs
Fire equipment/fighting signs show you where fire equipment is. What colour do we think of for fire? Red. But we already used red, with the prohibition sign. Well, fire equipment signs are also red, but a different shape.
These signs are square or rectangular in shape. The pictogram is white on a red background, and will often have a white border.
Colour: Red
Shape: Square
Meaning: Here is the fire equipment, Fire extinguishers, Fire alarm
Examples:
