There is often confusion over which colors are allowed when choosing an Exit sign for your building. Exit sign requirements vary by state and municipality, which is why it's important to check with your Fire Marshall to see whether Green Exit Signs
or Red Exit Signs are required in your building. The information below is for general guidance, only. For many, however, it is also important to get a “sense” of any color preference – so that your building is as consistent as possible with others in your area. Even though the European Union generally uses Green
Exit Signs (Red is used to specify prohibited actions), our UL 924 standards allow either Green Exit signs or Red Exit signs. Yet, localized codes often specify one or the
other.
State Summary
New Hampshire accepts any color Exit sign, as long as it contrasts the room color. For example, a green room should not have a green Exit sign. This is unique to New Hampshire Exit Sign code, although it offers some real common sense and background into how Exit Sign codes were developed in the first place. While contrast is the primary motivation behind this code, it is important to keep principles like these in mind when you are choosing all safety signs of this nature.
