Introduction
Fire investigation is an important duty of public security fire control institutions, the cause of the fire as conclusions not only to the interests of the parties, but also related to the
Image and social stability and public security fire control institutions and revision of relevant policies, regulations and norms.
Science and accurately identify fire cause must be scientific, standardized technical basis. Our fire investigators technical staff after years of fire
Disaster investigation work, accumulated a lot of experience and formed a set of science, technology and research systems. In order to have these
Been a lot of actual fire field-proven experience and more standardized method to increase the fire cause identification technology content, improve the fire cause identified
Given accuracy, reduce fire Cause Determination arbitrariness, it is necessary to develop this standard.
