Methods and Materials For the experimental studies, three aerosol fire extinguishing generators (AFEG) were used, each with a fire extinguishing charge mass of 2800–2880 g.
The main components of the generator casings were made of heat-resistant alloy materials supplied by the company "MetalExpo" (Ukraine).
