Testing ogranophosphorus, organofluorine, and metal-containing compounds and solid-propellant gas-generating compositions doped with phosphorus-containing additives as effective fire suppressants

The development and investigation of new effective and environmentally clean flame suppressants is a promising direction in fire extinguishing. Organophosphorus and metal-containing compounds are the most promising candidates for the replacement of CF$_3$Br. However, for many of these compounds, data on their minimum extinguishing concentration are not available. In the present work, the minimum extinguishing concentrations for a number of new phosphorus-and metal-containing compounds and some of their mixtures, solid-propellant gas-generating compositions containing phosphorus additives were determined using the cup-burner technique and a setup with a turbulent flame source and transient application of flame suppressants.
