Smoke and toxic gases kill more people than flames do.
Most fire deaths are not caused by burns, but by smoke inhalation. Often smoke incapacitates so quickly that people are overcome and can't make it to an otherwise accessible exit.
The majority of fire-related deaths are caused by smoke inhalation of the toxic gases produced by fires.
The characteristic biphasic distribution of carboxyhemoglobin in fire victims together with other observations suggest that the principal causes of death are carbon monoxide followed by carbon dioxide poisoning and/or oxygen deficiency, while the influence of heat is considered to be of minor importance.
According the U.S. Fire Administration (USFA), smoke is the killer in 60% to 80% of all fire deaths. Recent research has revealed that hydrogen cyanide present in smoke generated at building fires may play a more significant role in injuries and deaths of firefighters and civilians than once thought.
During a fire, the concentration of oxygen (O2) typically drops to 10-15%, at which point death from asphyxia occurs. Between 60% and 80% of all sudden deaths occurring at the scene of a fire are attributed to smoke inhalation.
Exposure to wildfire smoke over 5 to 7 days can cause damage to the lungs, blood, and heart and cause strokes. There is no safe distance from smoke.
Smoking is the most common cause of fire-related deaths. Nearly two-thirds of all house fire-related deaths occur in homes without working smoke alarms. Most people who die in house fires are killed by the smoke, not the fire.
In most fire deaths, the cause of death is the inhalation of carbon monoxide and other products of combustion.
Most people who die in fires die from the toxic gases, thick smoke and lack of oxygen. In a fire, breathing even small amounts of these toxic elements can be disorienting, causing some people to pass out. Remember smoke detectors save lives. The time to react to a fire/smoke alarm is when it first goes off.
Whilst they can start naturally, see Information note - Wildfire, it is estimated that 90% of all wildfires across the globe are caused by humans. About 30% of those are started as a deliberate act of arson, whilst 70% are started accidentally or as a direct result of human carelessness.
Home fires are more likely to start in the kitchen than any other room in the home. The second leading cause of home fires are heating sources like wood stoves, and fireplaces. Fires caused by smoking are the leading cause of deaths.
Mattresses and bedding can catch on fire easily. Do not smoke in bed because you might fall asleep with a lit cigarette. Put your cigarette out in an ashtray or bucket with sand. Use ashtrays with a wide base so they won't tip over and start a fire.
Radiant heat is the biggest killer. As the fire front passes you will be subject to radiant heat, which is many times hotter than the air temperature.
Fire safety rule No. 1: Observe and think.
The smoke can restrict oxygen flow into the body and contain poisons which can be lethal. The heat of the fire will cause significant damage to the body. The fire will cause the soft tissues to contract, which causes the skin to tear and the fat and muscles to shrink.
Breathing in harmful gases can cause serious respiratory problems with up to 80% of deaths from a fire being caused from breathing in toxic gases. Symptoms of this can include coughing, vomiting, sleepiness, confusion and burns to the nose, mouth and face.
Smoke inhalation is the most common cause of death in house fires.
Experiencing a house fire can be one of the most traumatic events in a person's life. The aftermath can feel overwhelming, leaving victims unsure about what to do next. But remember, you're not alone. There is a network of assistance for house fire victims available to help you through this tough time.
fire victims have been alerted to the presence of the fires and have made unsuccessful efforts to escape. Most of the victims are found in bedrooms (59070).
Definition. A flashover is the near simultaneous ignition of all combustible material within an enclosed area. When many materials are heated, they release flammable gases. Flashover occurs when the majority of surfaces within the enclosed area are heated to the auto-ignition temperature of those flammable gases.
Prop up your head on pillows to help you breathe and ease a cough. Suck on cough drops or hard candy to soothe a dry or sore throat. Cough drops do not stop a cough. Take cough medicine if your doctor tells you to.
Wood smoke is worse
There is nothing special about wood smoke that makes it less harmful to inhale than cigarette smoke. In fact, research evidence tells us it is worse.
Class B fires are fires in flammable liquids, gases, and greases. Class C fires are fires which involve energized electrical equipment where the electrical nonconductivity of the extinguishing media is of importance. (When electrical equipment is de-energized, extinguishers for Class A or B fires may be used safely.)
