NCJRS Celebrates National Library Week April 12-18

National Library Week

Started in 1958, National Library Week is a nationwide observance celebrated by all types of libraries - including the NCJRS Virtual Library. NCJRS invites you to explore the breadth and scope of the NCJRS Virtual Library collection and services. With more than 220,000 collection documents and 60,000 online resources, including all known Office of Justice Programs works, it is one of the world’s largest criminal justice special collections.

We encourage your Feedback. Tell us how you use the NCJRS Virtual Library and Abstracts Database, how you access the collection, and any ways we can improve our services.

  Annotation: This scientific description of spontaneous ignition and an associated theory provides the fire investigator with the knowledge needed to determine whether such ignition has occurred.
Abstract: Spontaneous ignition is initiated through heat transfer or the inability to cool a hot material. The process starts as a chemical reaction that is not yet combustion; the consequence of ignition can be smoldering or flaming. The key variables involved in this process are the size of the material and the nature of the heat transfer, as well as the particular chemical and physical properties of the material. In any fire investigation, it is important for the investigator to recognize the signs of spontaneous ignition and to learn how to estimate whether it was possible in the particular fire pattern. This requires collecting samples for measurement. It is also important for forensic laboratories to have the capability and understanding to perform tests that can determine whether spontaneous ignition has occurred. Three scenarios for spontaneous ignition are considered in this report: a cold material in hot surroundings, a material on a hot surface, and a hot material in cold surroundings. A survey of just over 200 investigators inquired about their experiences with spontaneous ignition. Most of the incidents of spontaneous ignition reported involved materials infused with linseed oil, wet hay storage, and problems with clothing just taken from a dryer. Other cases involved potting soil, mulch, and a variety of other materials. The current study focused on linseed oil and cotton. The properties needed for spontaneous ignition were measured with two methods. The testing required a specialized oven. The two testing methods are described. Examples are provided on how to use the material and a technique for measuring the heat transfer coefficient of the oven. A database of property data was compiled. 4 tables, 10 references, and a listing of nomenclature
