When should a company officer call an agency authorized fire investigator in fire cause determination?

Calling an agency authorized fire investigator for fire cause determination is crucial when the specific cause of the fire cannot be determined by the on-scene personnel. In such scenarios, an authorized investigator possesses the specialized training, experience, and resources necessary to conduct a thorough investigation. They can properly analyze the evidence, utilize advanced methodologies, and apply their expertise to discern the cause of the fire accurately. This is particularly important in cases where the stakes are high, such as potential criminal activity, insurance claims, or large-scale incidents that could impact public safety.

While conflicting testimonies from witnesses may warrant further investigation, it is not the primary reason to involve a fire investigator. The presence of unusual materials or taking testimony are also relevant factors but do not inherently trigger the need for a specialized investigation. The definitive need arises when the initial investigation by the fire officers does not yield a clear understanding of the fire's origin and cause. Thus, the role of the investigator is vital in scenarios where ambiguity exists, ensuring that a comprehensive and accurate assessment of the fire incident is provided.
