What we will learn today • We will talk about what is so dangerous about fire and how fire produces different conditions that can affect your ability to survive a fire.
We have already learned that: • Fire is very hot • Fire is very fast • Fire produces very dark smoke that contains poisons
Most deaths and injuries are not caused by the flames • excessive heat • temperatures can reach 500 degrees in less than three minutes • inhaling the smoke • lack of oxygen (suffocation) • Why do people die in fires?
Heat and smoke rise • important to crawl low in smoke • air is cleaner and cooler
Gets so thick and black that you can’t see • can’t find your way out • Can cause irritation when inhaled • causes choking and you can’t breathe • Can cause confusion because you can’t see or breathe • Why is smoke dangerous?
Materials that make poisons when burned • Couches and chairs • fabric treated with stain repellants • wood treated with preservatives • Carpet • treated with stain repellants • Curtains and blinds • treated with cleaning solvents • Stereos and televisions • made with plastics that have chemicals in them • What makes smoke so dangerous?
Oxygen makes up about 21% of the air we breathe • We need that 21% to survive • Anything less can harm our bodies • The more a fire grows, the more oxygen it takes and the less we have • Fire Eats Oxygen
21% Normal Conditions 17% Some muscle impairment-increased breathing 12% Dizziness, headache, fatigue 9% Unconsciousness 6% Death within a few minutes
The best way to prevent heat and smoke exposure is to prevent the fire in the first place • Never play with fire • Keep things that will burn away from heat sources
