The St. Paul / Minneapolis area will see primarily red Exit signs. While the Minnesota State Building code has slightly different provisions than the NFPA Life Safety Code, the state generally follows the Life Safety Protocol. Technically, NFPA 101 code that is "more restrictive" than the MN building codes are not applied in the state. Since these restrictions go beyond the requirements for illuminated Exit signs, it is best to contact your local Fire Marshal for details regarding sprinklers and egress path equipment other than Exit Signs. Minnesota Exit Signs will vary depending on the area.
