Transcript of Fires
Where Is It Most Likely To Occur?
Forest Fires are most common in places that have moist enough climates to allow trees and shrubs to grow, but also have long hot and dry periods. in Canada and north America, forest fires occur in the dry forests and grasslands.
What are forest fires?
Low: Most of these fires are most likely to be self extinguishing.
Moderate: Small surface fires. Easily can be out out by ground crews with pumps and hand tools.
High: Strong surface fires. Difficult for ground crews to put out usually need bulldozers, tanker trucks, and aircraft to contain the fire.
Very High: High and intense fires. Impossible for ground crews. Requires air attack with retardant to put out the fire.
Extreme: Fast spreading, high intense fires. Very difficult to control.
NIL: No calculations recorded for those regions.
As you can see, the worst fires in Canada happen in parts of Manitoba, Saskatchewan and most of Alberta.
The Black Dragon fire
The Black Dragon Fire took place in China in May of 1987. It burnt 72, 884 square kilometers along the Amur river, with three million acres destroyed. The cause was due to parched land and high winds. According to New York Times, the Chinese sent two armies of regular troopsand thousands of forestry workers to fight the fire. By May 7th and 8th, 200 people died and 250 were injured.
Forest fires are a natural or man made fires. They can take hours for crews to sustain control of the flames.
most forest fires are caused by human activity
This is a picture of wild fires affecting natural systems.
Climate is a big factor in forest fire. They cause 42%
of fires each year.
This is wild fires affecting people.
How Does This Disaster Occur?
wild Fires occur from many different situations, Including human error. 4 out of 5 wildfires are caUSED BY PEOPLE. 3 THINGS ARE NEEDED FOR A WILD FIRE TO SUCCEED. THIS INCLUDES FUEL, OXYGEN, AND A HEAT SOURCE. FUEL IS USUALLY THE GRASS, TREES, OR EVEN HOMES. THE OXYGEN IS IN THE AIR. HEAT SOURCES CAN BE Lightning, burning campfires, cigarettes, hot winds, and even the sun can all provide sufficient heat to spark a wildfire.
WHAT YOU SHOULD DO:
The impact of forest fires
Forest fires can cause allot of damage to an ecosystem
n some cases animal can get killed by debris
the air gets polluted and vegetation is destroyed
homes can burn down and animals get hurt
food gets destroyed and or burnt
allot of money goes to waste to fix the ecosystem
1. Know Your Risks: Found out if you live in an area where forest fires cold happen.
2. Make A Plan: Work with your family an have a plan in case a forest fire does strike.
3. Get A Kit: You can buy these from the Red Cross or make your own.
Learn fire safety techniques and work with your family Go over "Stop, Drop, and Roll"
Practice fire drills twice a year and make sure you have an escape plan
Have a fire extinguisher in a good spot
Instal smoke alarms
Can Wild Fires Be Predicted?
IF it's the case that it's caused by lightning or weather we can have an idea if there will be one becuase lighting can strike and start a fire.
On the other hand, if it is caused by people we cannot really predict it because nobody will know what you are doing when you are in the woods.
Close all doors and windows
cover vents, windows and other openings with duct tape or plywood
Park your car positioned forward to the driveway, keep car windows closed and have valuables packed in the vehicle
Turn off propane and any other natural gases
Move items that easily light on fire such as curtains, and furniture away from the window
Turn all the lights on
Listen to your local radio station for up to date info on the fire and possible closed roads
Check on family members, neighbors and friends who may need special assistance (elderly, disabled, ill)
the human impacted
a forest fire can cause multiple deaths of humans and animals
it will cost a lot of money to fix the forest and that will affect the economy
all the trees and animals will die so people cant see them and wont want to come to destroyed environments
also maple trees might be burned and that will stop income for the park
if the fire is really dry it can spread to houses and citys in some cases
The heat is what gets the fire started. the heat needs to be in the triangle because it is wasn't in the triangle it would not start.
the fuel is gas, diesel, AND WOOD (ETC.) . ITS WHAT GETS THE FLAMES HIGHER AND KEEPS THE FLAMES GOING. NO FEUL MEANS THE FIRE WILL NOT KEEP BURNING.
A fire needs oxygen to BURN. ITS AS SIMPLE AS NO OXYGEN NO FLAME.
What dose a fire need to
- most wildfires are caused by human error.
_Percent of fires caused by people: 58%
-Percent of fires caused by lightning: 42%
- over 10 000 wilfires takeplace a year in Canada
-wild fires can travel up to speeds of 14 miles per hour
But according to statistics, British Columbia has the most per year (aprroximentally 1,704)
