(a) Placing, storing, locating, or displaying of fireworks in any window where the sun may shine through glass onto the fireworks so displayed or to permit the presence of lighted cigars, cigarettes, or pipes within 10 feet of where the fireworks are offered for sale is hereby declared unlawful and prohibited. At all places where fireworks are stored or sold, there must be posted signs with the words "FIREWORKS - NO SMOKING" in letters not less than four inches high.
(b) No fireworks shall be sold at retail at any permanent location where paints, oils or varnishes are for sale or use unless kept in the original unbroken containers, nor where gasoline or other flammable liquid or gas is used, stored or sold, if the use, storage, or sale creates an undue hazard to person or property. No fireworks shall be sold at retail from any temporary or moveable stand where paints, oils, or varnishes are for sale or use unless kept in the original unbroken containers, nor within 50 feet of where gasoline or other flammable liquid or gas is used, stored or sold.
(c) Any fireworks devices that are readily accessible to handling by consumers or purchasers must have their fuses protected in such a manner as to protect against accidental ignition of an item by a spark, cigarette ash or other ignition source. Safety type thread wrapped and coated fuses shall be exempt from this provision.
(d) No retail permit shall be issued for the sale of fireworks at retail from tents or from or in a motor vehicle or from a trailer towed by a motor vehicle. A permit may be issued for the sale of fireworks from a modular or mobile building when the structure is eight feet or more in width and thirty-two feet or more in length, from which all wheels have been removed and the structure placed on a non-mobile foundation. No permit shall be issued to an applicant for a previously unpermitted location, until the premises where fireworks are to be stored or sold have been inspected by the State Fire Marshal or his designated representative and it shall have been determined that such building and facilities within the building and facilities for storage meet reasonable safety standards for the storage and sale of permissible fireworks. Inspection is not required for renewal of permits at the same location to be operated by the same owner unless there has occurred substantial structure or environmental changes.
