Abstract Purpose. Experimental obtaining of the frequency characteristics of the class B fire when it is being extinguished by water spray.
Methods. Using the Heaviside function for obtaining the dynamic characteristic of class B fire when it is being extinguished by water spray.
Findings. Analytical expressions of the frequency characteristics are obtained and its graphical interpretation is presented.
Application field of research. The obtained models could be used for water spray extinguishing systems for class B fires.
Conclusions. The expressions for the frequency characteristics of the class B fire while extinguishing by water spray are obtained.
Keywords class B fire,spraying water, frequency characteristics
