There are many liabilities to owning, manufacturing, selling and using fireworks. The potential personal liabilities for injury to consumers caused by fireworkscan be devastating to those involved but taking precautions and having warning labels/notices can reduce these risks. Taking on larger businesssales of fireworks should include changing from a sole proprietorship to a LLC. With this transition there would also be an increase in employees or independent contractors in order to manufacture more product for the high volume of orders. Creating a valid contract is most important to have before making any of these necessary changes to a business or else there would be a devastating effect on the manufacturing party.
