Abstract
One carload of wood fiberboard burned in transit and eight carloads burned in a warehouse 15 days after shipment, causing $2,609,000 loss. Tests to determine the susceptibility of wood fiberboard to self-heating revealed that the ambient temperature to cause ignition varied inversely with the size of the specimen, ranging from 603 deg F for a 1/8-in. cube to 252 deg F for an octagonal prism 12-in. thick by 12-in. high and 228 deg F for a 22-in. prism. Pronounced self-heating was evident when the surrounding are was held at 147 deg F.
