Before thermal fogging an unoccupied structure, what local authority should be informed?

Before conducting thermal fogging in an unoccupied structure, it is essential to inform the local fire department. This is primarily because thermal fogging involves the creation of fog or mist from chemical solutions, which can produce vapors and odors that might trigger alarms or be mistaken for smoke by passersby or responders. Notifying the fire department allows them to be aware of the activity taking place, preventing unnecessary emergency responses and ensuring that safety protocols are acknowledged and followed.

While other authorities, such as the health department or environmental regulatory agencies, might sometimes be relevant depending on the substances being used or the regulations in place, the immediate concern when it comes to the actual execution of thermal fogging operations is to make sure that the fire department is aware of the activities within their jurisdiction. This action is crucial for maintaining safety and communication during the process, especially in areas where there might be a risk of misinterpreted emergencies.
