NFIRS 5.0 Element: ‘Type of Material’
This field is required only if the Item First Ignited code is “00” or a code less than “70.”

Be certain to enter the first material ignited by the heat source. For example, if an arsonist poured gasoline on a wooden floor, it was the gasoline and not the wood that was the material first ignited.
If an insulated wire short circuits, it may be the wire’s insulation that was first ignited; or it may be the wood studs in the wall, thermal insulation nearby, or another material.
