Most of the accidents pertaining to fireworks, take place, when you package the crackers in defective carton boxes. This should apparently not happen. You need to package the crackers in thermocol or silicon packets first and then seal the fireworks in a double layered carton box. This makes sure, the gun powder or dust, with which the crackers are made of, does not get in contact with the external surroundings, leading to a major fire accident. You can research on the internet, to get a fair idea, on other safety mechanisms that need to be applied, while packaging fireworks. The online store, you can try visiting is Fireworksshop.
