Minn. R. agency 144, ch. 4620, MINNESOTA CLEAN INDOOR AIR ACT, pt. 4620.0500
All signs used to identify a location where the responsible person prohibits smoking in an entire public place, place of employment, or public meeting must use the statement, "No smoking is permitted in this entire establishment" or a similar statement. If smoking is permitted anywhere within a public place, place of employment, or at a public meeting, the sign must state, "Smoking is prohibited except in designated areas." All signs used to identify a smoking-permitted area must use the words "smoking permitted" or the international smoking symbol, or both. Signs that are used to identify a nonsmoking area must use the words "no smoking" or the international no-smoking symbol, or both.
Signs must be conspicuously posted on or immediately inside of all outside entrances to the public place, place of employment, or public meeting. All signs used to identify smoking-permitted and nonsmoking areas must be placed at a height and location easily seen by a person in the establishment and must not be obscured in any way.
The boundary between an acceptable nonsmoking area and a smoking-permitted area must be clearly designated so a person can differentiate between the two areas.
Signs used to designate acceptable nonsmoking and smoking-permitted areas must use printed letters of not less than 0.5 inches (1.3 centimeters) in height. Whenever either of the international symbols is used, the diameter of the outer circle must not be less than three inches.
