  2. What is the Myth? • Spalling: breaking off of pieces of the surface of concrete, cement or brick due to intense heat. Brown stains around the spall indicate the use of a fire accelerant. • Numerous laboratory tests which saturated concrete with gasoline and other flammables (even torches were used on some) failed to produce the spalling.

  3. Why is it a Myth? • Because many have misinterpreted it as just being associated with arson • Spalling does not normally occur due to arson • The spalling may be an indicator of the use of accelerants

  4. How does it affect investigations? • Many consumers have lost everything to their insurance company because of this one faulty indicator alone • Fire investigators have argued endlessly about the characteristics of an accelerant-induced spall versus a naturally occurring one

  5. Spalling can occur with accelerant or without
