Be a safe swimmer. Water sports and fireworks are two of the biggest pastimes for Fourth of July celebrations, and these are both linked to numerous deaths and injuries each year. Never swim alone, and make sure that kids' water play is adequately supervised at all times. Many children or adults drown occur when other people are nearby, so always have a designated chaperone for water play and don't assume that others are watching the kids. Statistics show that most young children who drown in pools have been out of sight for less than five minutes. Alcohol consumption also increases the risk of accidental drowning.
Apply sunscreen both before and during an outdoor party. Ultraviolet rays from the sun can cause both premature aging and skin cancerr in the long term, and a painful burn the next day. Even those with darker skin should use a sunscreen with a minimum sun protection factor (SPF).
Check prescription medications you are taking to assure you will not have a sun-sensitizing drug reaction to the medication.
Keep children away from campfires and grills. Gas leaks, blocked tubes, and overfilled propane tanks can be a cause of grill fires and explosions.
Don't leave the picnic spread out all day. Allowing food to sit in outdoor temperatures can invite food-borne illness. The U.S. FDA suggests never leaving food out for more than one hour when the temperature is above 90 F and not more than two hours at other times. Foods that need to be kept cold should be placed in a cooler with plenty of ice or freezing packs and held at a maximum temperature of 40 F. While mayonnaise and other egg dishes are often associated with food poisoning, any food can potentially become contaminated. Adequate hand washing and food preparation can also help prevent food poisoning.
Use alcohol responsibly. Alcohol and fireworks can be a hazardous and dangerous combination. Also, have a designated driver to bring partygoers home from the festivities. Remember also that alcohol and swimming can be as dangerous as drinking and driving.
Lakes, waterways, and seas will be crowded with boats. Review safe boating practices, and don't drink and drive your boat. Alcohol consumption while operating boats or other motorized water vessels is illegal, and you can be arrested for a BWI (boating under the influence). Be sure that you have an adequate number of life preservers on hand for extra guests. Become familiar with the boating laws in your area.
