Fireworks have long been a beloved tradition during Fourth of July celebrations, lighting up the night sky with dazzling colors, booming sounds, and vibrant displays. Whether you’re at a public event or setting them off in your neighborhood, fireworks are synonymous with Independence Day festivities across the U.S.

However, behind the sparkle and spectacle lies a serious set of concerns that are often overlooked, especially when it comes to air quality and health.

According to the Northwest Clean Air Agency (NWCAA), one of the highest annual spikes in fine particle pollution in area counties occurs on the night of July 4 and into the early hours of July 5. This sharp rise is directly linked to the widespread use of fireworks. Aside from wildfire smoke and winter woodstove burning, fireworks are among the region’s top contributors to unhealthy air.

Fireworks smoke contains a mix of harmful pollutants, including fine particulate matter (PM2.5), sulfur compounds, and heavy metals like barium, strontium, and copper, which are used to produce the colors we see in fireworks displays. These pollutants can easily be inhaled deep into the lungs, especially for people with asthma, heart disease, or other respiratory issues. Children, seniors, and those with compromised immune systems are particularly vulnerable.

Beyond health concerns, fireworks also present serious fire and safety risks. Dry grasses, brush, and trees can easily ignite from a stray spark or ember, leading to destructive wildfires or structural fires. Fire departments across the Northwest typically see an uptick in fire-related incidents and emergency room visits due to burns and other injuries during the holiday.

If you do choose to celebrate with fireworks this year, make sure to plan ahead and take appropriate safety precautions:

Use fireworks only in legal and safe areas. Always follow local laws and burn bans, which may vary by city and county.
Keep a bucket of water or a hose nearby. Douse used fireworks with water before disposal to prevent accidental fires.
Wear protective eyewear. Many injuries can be avoided with simple precautions.
Avoid lighting fireworks near dry grass, trees, or buildings.
Protect your lungs. Try to stay upwind of fireworks smoke and limit exposure, especially if you or your family members are in a sensitive health group.
