Yeah, but I think now night clubs have to adhere to stricter interpretation of fire codes than any other type of establishment, simply because it's often people crowded into a small area with poor lighting and many patrons may be under the influence of drugs and/or alcohol.
I wouldn't doubt it if pyrotechnics are banned completely from night clubs here in the US given the one fire in the N.E. that killed clubbers when the pyrotechnics caught the building on fire.
