Fire shelter - Looking very much like an aluminum foil puptent, the fireshelter is carried by each firefighter. Firefighters find an area clear of burnable vegetation, or clear an area themselves. Then they place their hands and feet in straps at each corner of the shelter and lay on the ground on their stomachs with their feet towards the advancing fire. The tent traps air over them which is maintained at a cooler temperature than the surrounding fire by the reflective material contained in the shelter's fabric. This trapped cool air protects the firefighters' lungs from the hot air of the fire and the shelter shields them from the flames themselves.
Firefighters remain in the shelters until released by the crew boss.
This may take some time as they must be completely confident that they are no longer in danger from the fire. Fire weather - A weather prediction prepared specifically for use by fire managers. It covers weather elements that may have direct impacts on fire behavior and how a fire is attacked. Fire break - A natural or constructed barrier used to stop or check fires. Crews construct fire lines by using shovels, pulaskis, rakes and chainsaws to clear the line of vegetation so that the fire will have nothing to burn when it arrives at that point.
