Areas documented during the course of the investigations include details of fire ignition, growth, and development; contributions of building construction, interior finish and furnishings; fire detection and suppression scenarios; performance of structures exposed to the fire; smoke movement and control; human reaction (response) and evacuation; firefighting and rescue; fire propagation as a function of human reaction time; and the extent of life loss, injury and property damage.
Fire investigation, like crime scene investigation, can involve several disciplines. In more complex cases, there will be issues other than whether the fire was intentionally set or not.
TFES investigation unit collects, analyses, and reports detailed fire experience data through on-site investigations of technical or educational significance. Reports may take form by full reports, preliminary/summary reports; alert bulletins; or journal articles.
