We are opening our New hospital soon and I have a question regarding Fire Extinguisher signs.   I believe we fall under NFPA 10 2010.   Is it required to place signage on doors of rooms that have Fire Extinguishers inside the room.  For example:  A small machinery room has a fire extinguisher inside.  Is it required to have a sign on the door?
