What we will learn today

• We will learn about the fire triangle and how we can prevent a fire from happening

Page 3: What is Fire?

We have already learned that:

• Fire is not like we see on television

• It is very hot, moves very fast and makes everything very dark

Page 4: What is Fire?

We have also learned that:

• It takes three things to cause a fire:

– Heat - or something that is hot– Fuel - or something that will burn– Oxygen - the air that is all around us

Page 5: What is Fire?

Do we know what a triangle is?

Three sided shape - needs all three sides to

be connected to be a triangle

Page 6: What is Fire?

The same way that the three lines have to be connected to form a triangle, the heat, fuel and oxygen have to be connected to cause a fire.

Page 12: What is Fire?

Remove the HEAT sources, and there is nothing hot to start the fire

If we remove any one side of the triangle, the fire cannot happen

Page 13: What is Fire?

Remove the FUEL sources, and there is nothing to burn.

If we remove any one side of the triangle, the fire cannot happen

Page 14: What is Fire?

Remove the OXYGEN and there is nothing to feed the fire.

If we remove any one side of the triangle, the fire cannot happen
