Req 3c–3d — Burns & Carbon Monoxide

Burns come from many sources, not just direct contact with flames. And carbon monoxide—a gas you cannot see, smell, or taste—kills hundreds of Americans every year. Understanding both helps you stay safe and help others.

Most Frequent Causes of Burn Injuries

Scalds: Hot Water & Steam

The most common source of burn injuries overall. Boiling water, steam from pots, hot tea, bathwater that’s too hot—these cause scalds. Scald burns are often worse than you’d expect because steam transfers heat faster than water and can cause deep burns. A cup of boiling water spilled on your chest will cause a second-degree burn almost instantly.

Prevention:

• Set water heater to 120°F (use a thermometer to check).
• Keep pot handles turned inward so they can’t be accidentally bumped.
• Never leave a pot of boiling water unattended.
• Test water temperature before a child gets in a bath.

Contact Burns: Touching Hot Objects

Touching a stovetop burner, a curling iron, a hot cast-iron skillet, or a space heater causes contact burns. These burns are often deeper than scalds because the object maintains its heat and continues burning skin while in contact.

Prevention:

• Never touch a stovetop or oven (hot even when off).
• Use oven mitts for all hot cookware.
• Keep space heaters away from bedding and flammable items.
• Unplug curling irons and hair straighteners after use.

Kitchen Fires & Grease Burns

Grease fires (when oil in a pan ignites) cause severe burn injuries. Even worse, people instinctively throw water on a grease fire, which makes it explode.

Prevention:

• Keep oil at a moderate temperature (don’t superheat).
• Never leave frying oil unattended.
• If a grease fire starts, cover the pan with a lid or fire blanket (cuts off oxygen).
• Never use water on a grease fire.

Campfire Burns

Sitting too close to a fire, falling into embers, or being burned by hot coals. Campfire burns are preventable through awareness and position.

Prevention:

• Maintain a safe distance (at least 3 feet from the fire).
• Never run or play near a campfire.
• Wear long pants and closed-toe shoes.
• Never sleep right next to embers or coals.

Clothing Fires (covered in Req 3b)

Electrical Burns

Touching a live electrical wire or faulty appliance. Electrical burns can cause deep tissue damage because electricity travels through the body, heating organs. Even minor-looking electrical burns require medical attention.

Prevention:

• Do not use electrical appliances in wet conditions (wet hands, wet floor).
• Ensure outlets near water have GFCI protection.
• Have an electrician check faulty appliances.

Airway Burns

An airway burn occurs when hot gases or steam damage the inside of your mouth, throat, or lungs. This is one of the most dangerous types of fire injury because swelling can block breathing within minutes.

Symptoms & Signs:

• Singed nasal hairs (a sign you’ve inhaled hot air)
• Coughing or difficulty breathing
• Hoarse voice or sore throat
• Drooling or difficulty swallowing
• Mouth or throat looks red or blistered

Treatment:

• Call 911 immediately. This is a medical emergency.
• Do not try to treat it yourself. Swelling can develop rapidly.
• Keep the victim sitting upright (to help breathing).
• Do not give the victim anything to eat or drink (their airway might swell and they might choke).
• Have the victim breathe cool, humid air (open a window or go outside if it’s safe).

Airway burns can kill by suffocation within hours, even if the external burns are mild. Always treat suspected airway burns as a life-threatening emergency.

Carbon Monoxide Poisoning

Carbon monoxide (CO) is a colorless, odorless, tasteless gas produced by incomplete combustion. You cannot detect it without a CO detector. It binds to hemoglobin in your blood more readily than oxygen does, gradually suffocating your organs from the inside while you have no idea it’s happening.

Common CO Sources:

• Car exhaust from a vehicle running in an attached garage
• Furnaces, water heaters, or stoves with improper ventilation
• Blocked chimneys or clogged vents
• Charcoal grills used indoors (never use a charcoal grill inside a tent, car, or enclosed space)
• Faulty space heaters or portable generators
• Fireplaces without proper draft

Symptoms & Signs of CO Poisoning:

Mild exposure: Headache, dizziness, weakness, chest pain, confusion

Moderate exposure: Severe headache, rapid heartbeat, confusion, loss of consciousness

Severe exposure: Loss of consciousness, seizures, heart failure, death

The tricky part: CO poisoning symptoms resemble the flu (headache, fatigue, nausea). People sometimes assume they have a cold, go to bed, and don’t wake up.

Prevention:

• Install CO detectors on every level of your home and near bedrooms. Test them monthly.
• Never run a car in an attached garage, even with the door open.
• Never use a charcoal grill indoors. Only use camping stoves (liquid-fueled or gas) in properly ventilated tents or outdoors.
• Have furnaces and chimneys inspected annually.
• Ensure all gas appliances are properly vented to the outside.
• Never block furnace or dryer vents.
• Use generators only outdoors, at least 20 feet away from windows, doors, and vents.

Treatment of CO Poisoning:

• Get to fresh air immediately. Leave the building.
• Call 911.
• If the victim is unconscious, perform CPR if trained to do so.
• In a hospital setting, hyperbaric oxygen therapy can help reverse CO damage to the brain.

The Hidden Threat

CO poisoning is more common than many people realize. According to the CDC, over 400 Americans die from unintentional CO poisoning annually, and thousands more are injured. Most cases happen in the winter when people seal their homes and rely on furnaces.

A particularly dangerous scenario: A Scout camping trip in a tent with a charcoal grill or camping stove running inside. Even a small grill producing CO in a sealed tent can kill everyone inside within hours. Always use camp stoves outside or in well-ventilated areas.

Now let’s shift from injuries to understanding how fires start in the first place.
