Many firework enthusiasts are looking for the next biggest high, fireworks that are more powerful, more explosive and shoot higher with more outrageous special effects. If a little firework action is good, then more is better – right? Well, we think so as long as you are following the limits of the law.
The legal limit of explosive material allowed in a consumer firework (called 1.4G or Class C) is 50 mg. If you were to take apart the firework, the amount of explosive compounds would only look like the size of a broken-in-half aspirin. Of course, if you look hard enough or know a kitchen table pyrotechnician, you might be able to find fireworks that exceed the 50 mgs. However, the purchase and use of these items is illegal and could cause serious harm to your physical self and nearby property. Not to mention, you could have to pay fines if caught.
If your are purchasing fireworks from a stand or other vendor and want to “spot check” to see if they are on the up-and-up, look for a manufacturer’s name on the label or box along with instructions and safety warnings. This information is required by law and if missing probably means you are handling contraband fireworks. Old-school fireworks like Cherry Bombs, M-80s, M-100s and silver salutes are contain too much pyrotechnic compound and are not allowable by law. However, some firework manufacturers make watered down versions with similar sounding names that are okay; if in question, just ask.
Your state and local jurisdiction will also have rules and regulations about what fireworks residents can buy and when they can shoot them off.  If you are unsure, please contact the home page of your state and contact the local fire or police department. If you come across fireworks that are illegal or thought to be suspicious call your local police force, fire department or Bureau of Alcohol, Tobacco and Firearms at 1-888-ATF-BOMB.
