Fireworks can be fun, but also very dangerous.Researchers with the Consumer Products Safety Commission say there were nearly 19,000 injuries caused by fireworks last year and more than 7,300 people ended up in the emergency room. Doctors suggest leaving the fireworks to the professionals, but if you do light your own, be sure to take precautions. And, you should never hold fireworks in your hand. Keep a bucket of water close by, and always wear shoes to avoid burning your feet. Of course, read all instructions on firework packaging before igniting.
