Why are escape signs green?
Everybody knows them, the green signs with arrow, which help us to leave a room, a building section or a building safely in case of danger. Those escape sign luminaires with green-white luminaires are an essential part of safety lighting. But why are they green?
There are guidelines for the appearance of escape signs, so that they can be recognized as such already at first glance. Those guidelines are regulated by various standards and regulations.
Since 2013 the general appearance of escape signs according to the international standard ISO 7010 is mandatory. This is intended to ensure that a uniform marking leads to less problems of understanding. This means that no text is used, as this could lead to misunderstandings among foreign-language people. The forms and colours are based on ISO 3864.
