Quiz: The Language of Safety Signs

Understanding safety signs is vital for us. These signs provide an information about a possible danger and hazard. Also, they show how to protect ourselves during these situations.

What does the language of safety signs mean? – You may wonder. Well, there are 3 main elements in every sign. These elements are the shape, color and the image on it. In order to understand the language of safety signs you should understand these 3 factors.

Safety signs are made using semiotics, which is the science of how colors, shapes and text affect human brains. Each type of signs has a certain color, shape and text.

The categories of safety signs

Different types of safety signs

There are 4 categories of safety signs. Let’s find what these types convey.

1. Emergency and first-aid signs

These signs give information about emergency exits, first aid, or rescue capabilities. Fire signs also fall into the category of emergency signs. In case of fire these signs provide information about emergency exits. Also, fire signs indicate the place of a fire extinguisher.

2. Mandatory signs

Тhese types of safety signs direct us to take a certain action. Just like in the second picture, which shows that a safety musk must be worn.

3. Prohibition signs

Тhese signs prohibit us to do a specific act that can cause danger. Like shown in the third picture, it is prohibited to walk there.

4. Hazard signs

Тhese signs warn us that there is a chance of danger. There are various hazard signs, for instance, electric risk signs, radiation risk etc.

The shapes of safety signs

You’ve probably noticed that each type of safety signs has a certain shape. This makes the sign recognizable without even seeing the pictogram on it.

Triangle – Warning signs

Round red – Prohibition signs

Round blue – Mandatory signs

Square and rectangular – Emergency signs

But what about the colors of safety signs?

Red color

Have you ever wondered why prohibition signs are red? Well, there is a reason for that.

Our eyes are most sensitive to red, so it is the first color we notice. And it is the only color that can be seen through fog and rain.

Red is the color of blood and burning objects, so when we see red our brain alerts us about a danger.

The red should take up at least 35% of the sign.

Blue color

Signs with mandatory information are in blue color with white pictogram on it.

As blue is connected with wisdom, power and intelligence that is why mandatory signs are blue.

The blue should take up at least 50% of the sign.

Yellow color

This is the color of warning signs. Which is again one of the colors that our eyes will easily notice.

It draws attention and warns of a potential hazard.

The yellow should take up at least 50% of the sign.

Green color

Green is the color of emergency signs. It associates with peace and nature.

Green is a less interfering color which blends easily with the surrounding. But at the same time can be easily noticed. The text color of the green signs is white. As it is the best combination to make the text easily readable.

The green should take up at least 50% of the sign.
