Tennessee Code Title 68. Health, Safety and Environmental Protection § 68-104-111

(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 ten feet (10′) of where the fireworks are offered for sale is 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 (4″) high. No fireworks shall be sold at retail at any location where paints, oils or varnishes are for sale or use, unless such paints, oils or varnishes are kept in their original consumer containers, nor where resin, turpentine, gasoline or any other flammable substance is stored or sold, if the storage creates an undue hazard to any person or property.

(b) All firework devices that are readily accessible to handling by consumers or purchasers shall have their fuses protected in such a manner as to protect against accidental ignition of an item by spark, cigarette ash or other ignition source. Safety-type thread-wrapped and coated fuses shall be exempt from this provision.
