Who cares if your wife is hanging off the deck yelling, “you’re going loose a finger and I’m not driving you to the hospital!” Heck, you’ve probably already burned off your eyebrows more than once. If you’re like many hardcore firework enthusiasts; you keep looking for the next bigger and better firework. It’s like an addiction; but, of all the terrible vices that man can have, shooting off pyrotechnics is not that bad.  So if you’re trying to push it to the limit when it comes to fireworks, just make sure you’re staying within the boundaries of the law – for your own safety and the safety of those around you.
The legal limit of explosive material allowed in a consumer firework is 50 mgs. These fireworks are called 1.4G or Class C . If you were to dismantle the firework, the amount of explosive compounds would only look like the size of an aspirin cut in half. Of course, if you search far and wide enough enough or know a DIY pyrotechnician, you might be able to find fireworks in excess of the 50 mg limit. However, the purchase and use of these items is illegal and could cause serious harm to your own personal self, other people standing and property in the vicinity. Additionally, your wallet is at risk – if caught, having possession of more than the legal limit of fireworks subjects you to fines.
If buying 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 supposed to be off the consumer market because they contain too much pyrotechnic compound – above and beyond what is legally allowable. However, in an effort to play off the memories of these old-school bad boys, some firework manufacturers make watered down versions with similar sounding names that are okay; if in question, just ask.
Your state and local jurisdictions 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 pyrotechnic devices that seem to be suspicious, do your duty as a citizen and call your local police force, fire department or Bureau of Alcohol, Tobacco and Firearms at 1-888-ATF-BOMB.
