FIRE IS DEADLY- (Smoke & toxic gases kill more people than flames do) Fire uses up the oxygen you need and produces smoke and poisonous gases that kill. … The odorless, colorless fumes can lull you into a deep sleep before any flames even reach your door. You may not wake up in time to escape.
What are the 4 ways fire spreads?
Generally, a fire can spread in four ways via heat transfer. These are through convection, conduction, radiation, and direct burning. CONVECTION – This is defined as the transmission of heat within a liquid or gas and is due to their difference in density.

Why do fires spread so quickly?
If a spark happens in the presence of oxygen and fuel—such as dry grass, brush or trees—a fire can start. And conditions in the weather and environment can cause the fire to spread quickly. Fires need lots of fuel to grow. … For example, drought, winds and extreme heat can make a fire bigger, faster and more dangerous.
What kills you first in a fire?
The Carbon Monoxide Might Kill You First When people were executed by being burned at the stake, they could die from carbon monoxide poisoning before the flames caused seriously damage to the body.
How fast does a fire spread?
Fires can travel quickly: up to 6 miles-per-hour in forests and up to 14 miles-per-hour in grasslands. If you have an upward-slope to your terrain, the flames can travel even faster; an extra 10 degrees of slope will double the speed of your fire.
