Where conditions are such as to make smoking a hazard in any areas of warehouses, stores, industrial plants, institutions or places of assembly or in open spaces where combustible materials are stored or handled, the Fire Marshal is empowered and authorized to order the owner or occupant, in writing, to post "no smoking" signs in each building, room or place where smoking is prohibited. The Fire Marshal shall designate specific safe locations, if necessary, in any building, structure or place in which smoking may be permitted.

"No smoking" signs of approved size lettering and location shall read, "By Order of the Fire Marshal."

It shall be unlawful for any person to remove any legally required "no smoking" sign or to smoke in any place where such signs are posted.

Any person who shall violate any of the provisions of this section shall be fined not more than $25.
