The working environment of a fire investigator after experimental fires: Challenges and experiences

Fire investigators are key players in determining the causes of fires. Their work has changed over the years, not only in their professional approach to identifying the causes of fire, but also in relation to the protection of their health, where there have been significant improvements in recent years. Unlike firefighters, fire investigators do not usually use an isolation breathing apparatus at fire scenes when fighting a fire. This article focusses on an analysis of the risks that fire investigators face in their work, particularly in terms of physical, chemical, and biological factors. It examines the potential impact of these factors on the health and safety of fire investigators compared to emergency firefighters and proposes measures to minimise these risks. Then it specifically looks at the working environment of a fire investigator in a post-experimental fire area. It concludes with strategies and technologies aimed at protecting the health of fire investigators in the challenging post-fire environment.
