Don't let these seven hazards ruin your Fourth of July fun.

4. Choking: Sadly, more than 3,000 people die each year as a result of choking, and some of the most common culprits include hot dogs. If frankfurters are on your Fourth of July menu, be sure to cut them lengthwise and then into smaller pieces, especially if you're feeding them to kids. And watch out for other summer fare that could pose choking risks, such as whole grapes, carrots cut on the diagonal, peanuts, and popcorn. In addition, don't forget to chew your food properly, and never walk or run while you have food in your mouth.
5. Sunburn: Sunburns can range in severity from cases of minor redness to those resulting in debilitation or even death. Fortunately, you can prevent them by wearing protective clothing, regularly applying a broad-spectrum sunscreen with an SPF of at least 15, and avoiding being in the sun during midday, when UV rays are at their strongest. If you notice any signs of severe sunburn, such as pain, blistering, headache, confusion, fainting, or nausea, get to an emergency room right away.
6. Food Poisoning: The sweltering weather can be a breeding ground for foodborne bacteria, such as E. coli and salmonella. To reduce your risk, wash your hands with antibacterial soap before and after food handling, cook meats and eggs thoroughly, and wash utensils and surfaces that come into contact with raw foods. If you notice any of the telltale signs of foodborne illnesses—nausea, vomiting, cramps, diarrhea, fever, bloody stool—be sure to seek out medical attention immediately.
7. Alcohol Poisoning: Fourth of July celebrations can set the stage for alcohol abuse. While adults should be careful to limit their consumption or refrain from booze completely, according to experts at the University of California San Diego Medical Center, even children may be at risk. Don't leave full or leftover cocktails lying around, and never allow a child to sip from your glass. In addition, driving while intoxicated is a common holiday risk, so make sure that you, your family, and friends never get into a car if the driver has been drinking.
8. Drowning: Tragically, some 3,000 drowning deaths occur in the United States every year, and most of the victims are children. In fact, drowning is the second leading cause of accidental deaths among children 1 to 14 years old. Don't forget to keep swimmers, and especially kids, in sight at all times. For very young children, the American Red Cross recommends staying within an arm's length reach. Adults should remember that alcohol and water sports don't mix.
9. Dehydration: Thousands of Americans suffer from dehydration every year. The good news: The condition is totally preventable. Remember to drink at least eight 8-ounce glasses of water a day; don't overexert yourself; stay in cool, shaded areas whenever possible and push beverages (water is best). Symptoms include darker colored urine, constipation, bloating, dry mouth, a lack of energy, and muscle cramping.
10. Heatstroke: Young children, the elderly, and people who engage in intense physical activity are particularly at risk for heatstroke. Be sure to drink plenty of liquids; wear light, loose-fitting clothing and a wide-brimmed hat; and avoid strenuous exercise in hot weather. If you suspect you or a loved one may have heatstroke, notify your local emergency services as soon as possible; avoid alcoholic, caffeinated, or carbonate beverages.
