Fire safety signs and lights serve several purposes and therefore have a variety of categories. They can contain images, text, or both. They can act as a warning, give directional advice, give information, and prevent fire from occurring. Fire safety signs also come in a range of colours that include red and white, green, blue, white, and black and yellow. Signs can also vary in their location. Fire safety information signs can be found in places like fire extinguishers, whereas fire exit signs can be found above doors, to direct an individual to safety.
All these fire safety signs are split into two groups; signs that prevent fire and signs that assist a person if there is a fire. Fire safety signs that prevent fire can also be categorised into three groups, based on the symbols they contain. These groups include warning signs, prohibition signs and mandatory signs.
Regardless of which group a fire safety sign falls into, they should all be easily understandable, easily visible, and positioned at the correct height, so that they can be seen from a distance.
Consistency is key to being able to interpret the meaning of signs in the stressful event of a fire. There are three different colour signs to help with the identification of various warnings - blue, red, and yellow. Each has its own goal around prevention, warnings, and prohibitive messaging.
