Once You Are Out STAY OUT!
Never re-enter! Results could be DEADLY!
One of the greatest hazards to life that exist in a building fire of any magnitude
is the lack of sufficient oxygen.
Oxygen not only is essential for human life, but also is key to supporting
the life of the fire. When fire and humans compete for the limited amount of
oxygen within a burning building, fire always wins!
Most fire fatalities are caused because of this. It is often referred to as
death from smoke inhalation but put in much simpler terms it is death by suffocation.
Once you have made your way out of a burning building you may already be suffering
the effects from lack of oxygen. These effects include:
||Normal Atmospheric Level
||Minimum Healthful Level
||Decreased Stamina and Coordination, also may induce early
symptoms described below
||Breathing rate increases with exertion, increase in heart
rate. Impaired coordination, perception, and judgement
||Breathing further increases in rate and depth, lips turn blue.
||Mental failure, fainting, unconsciousness, nausea, and vomiting
||Fatal after 6-8 minutes
||Coma in 40 seconds, convulsions, respiration ceases, and death
One of the major effects of lack of oxygen is the impairment of judgement.
You may not realize it, but the possible exposure of lack of oxygen on the way
out may impair your ability to think clearly and rationally. Even if you are
not affected, others who escaped with you may display this impairment of judgement. IT IS IMPORTANT TO PREVENT OTHERS FROM RE-ENTERING!
- The presence of toxic gases. Carbon Monoxide is a main by-product of fire.
It is odorless, colorless, and tasteless. In high concentration it can immediately
cause unconsciousness and subsequent death. Even in moderate amounts carbon
monoxide can cause impairment of mental functions much similar to lack of
- Burn injuries by fire itself. A building fire can generate heat upwards
of 1500 degrees F. Keep in mind that water boils at 212 degrees F, and that
most foods are cooked in temperatures of less than 500 degrees F. There is
the possible danger of flashover where a room is immediately engulfed in flames
in an explosion-like reaction.
- Gas mains, propane tanks, and even small arms ammunition can explode causing serious injury.
- Structural integrity. Ceilings and walls can collapse on top of you, the floors can fall from underneath your feet, and other structures such as stairways and porches can collapse.
- Electrical lines can become exposed inside the building and fall from outside connections to the ground on the exterior of the building. This can result in electrocution.
Go to a safe place (preferably prearranged) far enough away from the building in case of collapse or explosion and perform a head count of those who were in the building with you (family members or co-workers).
If someone is missing it is critically important that this be conveyed to arriving Firefighting Personnel. Tell them who and how many people are missing and where they were last seen. DO NOT GO BACK IN AND TRY TO FIND THOSE MISSING!!!
Seek medical care if you or any others who escaped from the burning building are injured. Keep in mind that the symptoms of lack of oxygen and/or exposure to toxic gases can closely resemble those of alcohol intoxication. Get these people immediate medical attention.
Seek shelter from the elements in a safe neighboring building, especially in the cold, rain, and extreme heat.
Ask Firefighting Officials or a neighbor to notify insurance company, nearby relatives or the Red Cross to arrange lodging (if applicable).
If you are not going to remain in the building, make sure your property is secure. Ensure the police are aware of the building being unattended. Lock up or board up open windows and doors.
The dangers of oxygen displacement in a burning building as well as other hazards including the presence of toxic gases, the fire itself, the risk of explosion, building collapse, and electrocution make reentering a burning structure a dangerous, if not deadly proposition.

Know When To Go! React Fast To Fire!
If you hear a fire alarm, get out and stay out. Smoke detectors and fire alarms protect you from fire. They sound an alarm to worn you that it's time to escape.

If you hear a fire alarm in a restaurant, mall, library, or other public building, leave the building immediately, following any instructions you hear over a public address system or from individuals who work in the building.
