The Connecticut Fireworks and Special Effects Code is not intended to prevent the use of any material, equipment, method of construction or installation procedure not specifically prescribed herein. The State Fire Marshal may grant variations or exemptions from, or approve equivalent or alternate compliance with, particular provisions of the Connecticut Fireworks and Special Effects Code, where strict compliance with such provisions would entail practical difficulty or unnecessary hardship or is otherwise adjudged unwarranted, provided any such variation or exemption or approved equivalent or alternate compliance shall, in the opinion of the State Fire Marshal, secure the public safety.

The State Fire Marshal may require the submission of sufficient supporting technical data to substantiate the proposed variation, exemption or modification.
