 The commission has a few tips to help people stay safe. It says to never use fireworks drunk or high and keep them away from children. Yes, even sparklers. The age group most likely to get injured and go to the ER was teens 15 to 19 years old, followed by kids age 5 to 9. The commission recommends setting off fireworks one at a time. Never try to relight a firework that didn't fully ignite the first time. And keep a bucket of water or a hose nearby in case something goes wrong. Sydney Lepkin, NPR News.
