Firework Burns and Explosion Injuries: Common Causes, Prevention, and First Aid

Fireworks can turn an ordinary evening into a memorable celebration, but they combine flames, explosive material, hot debris, and unpredictable movement in a device small enough to hold in one hand. When something goes wrong, there may be almost no time to react.

A fuse that appears to have gone out can suddenly reignite. A firework placed on uneven ground can tip toward spectators. A sparkler can burn a child’s hand, while an aerial device can cause severe injuries to the face, eyes, and fingers. Even someone who never touches a firework can be injured by a device that travels in the wrong direction.

According to the U.S. Consumer Product Safety Commission, an estimated 13,000 people received emergency-room treatment for fireworks-related injuries in 2025. Fifteen fireworks-related deaths were reported, with many involving misuse or device malfunctions. Burns accounted for 38% of emergency-room visits, while the hands and fingers were the most frequently injured body parts.

Knowing why these accidents happen—and what to do when they occur—can help keep a celebration from becoming a medical emergency.

Why Fireworks Can Cause Such Serious Injuries

Consumer fireworks are designed to create heat, pressure, light, sound, or movement through a rapid chemical reaction. Even relatively small devices may produce temperatures hot enough to ignite clothing, damage skin, or start a fire.

The danger is not limited to a dramatic explosion. Fireworks can cause several types of injury:

• Thermal burns from flames, sparks, or hot casings
• Blast injuries to the hands, fingers, face, and ears
• Eye injuries from fragments, chemicals, or impact
• Cuts and puncture wounds from exploding casings
• Hearing damage from close-range blasts
• Smoke inhalation
• Falls or collisions caused by panic
• House, vehicle, vegetation, or trash fires

The severity depends on the type of device, the distance from the explosion, the body part exposed, and whether burning material becomes trapped against the skin.

1. Holding Fireworks in the Hand

A common mistake is assuming that a small firework is safe to hold. If the fuse burns faster than expected or the device malfunctions, the explosion can happen before the user has time to throw or place it down.

The hands and fingers are especially vulnerable because they are closest to the ignition point. Injuries may include deep burns, broken bones, severe bleeding, nerve damage, and traumatic amputation.

Except for products specifically designed and legally approved to be held, fireworks should be placed on a stable surface and lit according to the manufacturer’s directions. Firecrackers, rockets, aerial shells, and similar explosive devices should never be held after ignition.

Never carry fireworks in a pocket. Friction, heat, sparks, or accidental ignition can set off multiple devices close to the body.

2. Returning to a Firework That Did Not Ignite

A firework that fails to launch may look harmless, but the fuse could still be smoldering internally. The device may ignite just as someone leans over it or attempts to pick it up.

This is one of the most preventable causes of facial, hand, and eye injuries. Never look down into a firework tube, place your face above a device, or attempt to relight a fuse.

The CPSC advises users never to relight or handle malfunctioning fireworks. Instead, stay away, prevent other people from approaching, and soak the device thoroughly with water before disposal. Follow the waiting time and disposal instructions provided by the manufacturer or local fire authority.

The safest rule is simple: if a firework fails once, the show is over for that device.

3. Allowing Children to Handle Sparklers

Sparklers are often treated as a child-friendly alternative because they do not produce a large explosion. However, they burn at approximately 2,000°F, which is hot enough to melt some metals, according to the CPSC.

In 2025, an estimated 1,300 emergency-room-treated injuries involved sparklers. Young children may grab the hot section, wave a sparkler near another person, drop it on their feet, or touch the glowing wire after the visible sparks stop.

Loose sleeves, costumes, dry grass, and long hair can also ignite. Children may panic and run while still holding the burning sparkler, creating a danger for everyone nearby.

CPSC recommends that children not play with or ignite fireworks, including sparklers. Consider safer alternatives such as glow sticks, LED wands, bubbles, confetti poppers without explosive charges, or light-up toys.

4. Pointing or Throwing Fireworks at People

Fireworks should never be treated like toys, weapons, or practical jokes. Pointing a Roman candle, bottle rocket, sparkler, or firecracker at someone can cause direct burns and blast injuries.

Even devices that appear to shoot only light or sparks may release hot fragments. Clothing can catch fire, and a person struck near the eye may suffer permanent vision loss.

Throwing a lit firework is equally dangerous because its path and timing cannot be controlled. It may land beneath clothing, inside a vehicle, on a roof, near stored fuel, or beside someone who cannot move away quickly.

Set a clear rule before the celebration begins: no pointing, throwing, chasing, or surprise ignition. If a guest ignores that rule, stop the activity rather than waiting for an accident.

5. Using an Unstable or Confined Launching Area

Aerial fireworks need a clear, open area and a stable base. A device placed on sloped pavement, loose soil, grass, or a wobbly platform may fall sideways after ignition. Wind can also redirect sparks, rockets, and burning debris toward people or buildings.

Never launch fireworks from glass or metal containers. If the device explodes inside, the container may break into dangerous fragments. Fireworks should also never be lit inside a house, garage, tent, vehicle, or other enclosed space.

Before lighting any legal consumer firework, look above and around the launch area. Keep away from:

• Homes, garages, sheds, and vehicles
• Dry grass, brush, leaves, and mulch
• Trees and overhead branches
• Power lines
• Propane tanks and fuel containers
• Crowds, pets, and livestock
• Roads and parking areas
• Balconies and wooden decks

Have a garden hose or bucket of water ready before the first fuse is lit—not after a problem begins. If conditions are dry, windy, or subject to a local fire restriction, skip the backyard display.

6. Ignoring Local Laws and Product Warnings

Fireworks laws differ by state, county, and city. A product sold in one area may be illegal to possess or use in another. Temporary restrictions may also be introduced during drought, wildfire danger, or extreme weather.

Purchase fireworks only from reputable, legal sellers. Avoid products that lack clear labels, instructions, manufacturer information, or safety warnings. Homemade or illegally modified fireworks can contain unpredictable quantities of explosive material and may detonate unexpectedly.

Do not combine fireworks, remove powder, shorten fuses, or place multiple devices together. Modifying a device changes how heat and pressure move through it, making its behavior impossible for an ordinary user to predict.

Professional displays are generally the safest option. They are managed by trained operators who establish controlled launch zones, account for weather, and keep spectators at a designated distance.

7. Mixing Fireworks With Alcohol or Drugs

Lighting fireworks requires balance, judgment, coordination, and the ability to react quickly. Alcohol and recreational drugs can interfere with all four.

An impaired person may stand too close, hold a device too long, forget which fireworks have been lit, or return prematurely to a dud. Alcohol can also encourage risk-taking, such as launching fireworks from the hand or aiming them at friends.

Choose one sober adult to manage any legal consumer fireworks. That person should read the instructions before dark, control access to unused devices, keep spectators behind a clear boundary, and stop the activity if conditions become unsafe.

Everyone else should remain at the established viewing distance. A crowded group gathered around the person lighting the fuse creates unnecessary risk.

Bystanders Can Be Injured Too

Following safety rules does not eliminate the danger if someone nearby is careless. Fireworks can fly into neighboring yards, explode earlier than expected, or send fragments far from the launch point.

Eye specialists regularly treat people who were watching rather than lighting fireworks. The American Academy of Ophthalmology notes that serious injuries may include thermal or chemical burns, retinal damage, and rupture of the eyeball.

Spectators should remain well behind the distance recommended on the product instructions. Protective eyewear can reduce some risks for adults handling legal consumer fireworks, but ordinary glasses do not make close-range exposure safe.

Small children, older adults, people with mobility limitations, and pets should watch from a protected location or attend a professionally organized display instead.

How to Prevent Firework Burns and Explosions

If consumer fireworks are legal in your area and you decide to use them, prepare before lighting anything:

• Read every label and instruction in daylight.
• Assign one sober, responsible adult to operate the fireworks.
• Keep children away from all fireworks, including sparklers.
• Use only one device at a time.
• Keep unused fireworks away from the ignition area.
• Place devices on a flat, stable outdoor surface.
• Never put any part of your body directly over a firework.
• Light the fuse at arm’s length and move away immediately.
• Never point or throw a device at another person.
• Keep a hose or bucket of water ready.
• Do not carry fireworks in a pocket.
• Do not modify, combine, or dismantle fireworks.
• Stop if wind begins directing sparks toward spectators or property.
• Soak spent fireworks before putting them in the trash.
• Leave malfunctioning devices alone and soak them thoroughly.

Footwear and clothing matter too. Wear closed-toe shoes, avoid loose synthetic clothing, and tie back long hair. Synthetic fabric may melt when exposed to heat and stick to the skin, worsening a burn.

First Aid for a Firework Burn

First, move away from active fireworks, flames, traffic, and smoke. If clothing is burning, use stop, drop, and roll, or smother the flames with water or a suitable fire blanket. Call 911 for a large, deep, or severe burn.

For a small thermal burn:

1. Cool the area under clean, cool running water.
2. Remove rings, watches, or other tight items before swelling begins.
3. Do not pull away clothing that is stuck to the burn.
4. Cover the injury loosely with sterile gauze or a clean, dry cloth.
5. Do not apply ice, butter, toothpaste, oil, or household creams.
6. Do not break blisters.

The American Burn Association recommends cooling minor burns with running water for at least five minutes and avoiding ice. Ice can further damage burned tissue.

Seek prompt medical care for burns that are deep, white, charred, numb, blistered over a large area, or located on the face, eyes, hands, feet, genitals, or a major joint. Burns involving children may need professional evaluation even when the affected area appears relatively small.

What to Do After an Eye or Explosion Injury

A fireworks eye injury is an emergency. Do not rub the eye, rinse it, press on it, apply ointment, or attempt to remove an embedded object. Do not give aspirin or ibuprofen before evaluation if there may be bleeding inside the eye.

Loosely shield the injured eye without applying pressure and seek emergency medical care. The American Academy of Ophthalmology recommends calling 911 or obtaining immediate treatment after a fireworks eye injury.

Call 911 after any significant explosion injury involving severe bleeding, an amputated finger, breathing difficulty, loss of consciousness, confusion, chest pain, hearing loss, or extensive burns. Do not attempt to remove embedded fragments. If there is heavy external bleeding and no object is lodged in the wound, apply firm pressure with clean cloth or gauze while waiting for emergency assistance.

Fireworks are meant to create excitement, but the safest celebration is one where nobody has to test their reflexes against a burning fuse. A professional public display offers the spectacle without asking families to handle explosive devices at close range. When consumer fireworks are used, distance, sober supervision, careful preparation, and respect for a malfunctioning device are essential.
