How Does Fire Spread? | Conduction | iHASCO

A fire can spread in three different ways if there’s enough fuel and oxygen to keep it going. It will spread through conduction, convection or radiation, but fires are often spread by a combination of all three.

Conduction is when heat moves through material and objects. Heat travels from the hot end of an object to the cooler end. This is also how one object can heat up another one by touching it.

We experience heat transfer through conduction all the time. For example, if I hold a hot mug of tea, the heat transfers from the mug to my hands.

Most metals are good conductors of heat so fires can easily spread from room to room through things like metal pipes or staircase handrails.

To see if heat from a fire is being CONDUCTED, you can touch a door with the back of your hand. If it’s hot, it means the fire is on the other side, so keep the door CLOSED.

FIRE DOORS delay the transfer of heat, smoke and fire for at least 30 minutes, so keep them closed. The materials that are used to make fire doors are especially chosen because they’re POOR conductors of heat.
