What makes fires spread faster?

What makes fires spread faster

WIND
Strong winds will make fires move much quicker. Small burning embers are blown over obstacles (e.g., walls, rivers, roads) and cause spot fires.

 

DENSITY AND SPACING OF HOMES
Fires move very quickly through areas where homes are close together. People cannot escape easily from dense settlements.

SLOPE
Fires spread much faster uphill than down.

MATERIALS
Thin items ignite quickly. Plastic sheets on roofs, curtains, rubbish bags outside, cardboard linings and newspaper pushed into holes provide a route for fires into homes.

MOISTURE
During dry seasons and droughts fires spread faster. However, many smaller fires occur in wet weather from indoor cooking and heating.
