摘要:
Предлагаемое изобретение относится к пожаротушению и может быть использовано для тушения пожаров класса А (твердые горючие вещества и материалы), а также лесных и торфяных пожаров. Задачей, решаемой в данном изобретении, является повышение эффективности способа тушения пожара, сокращение сроков тушения, а также повышение универсальности способа, то есть возможность использования различных специализированных устройств для тушения пожара. С этой целью предлагается тушить пожары с помощью наноразмерных форм огнетушащих веществ, получаемых в результате физико-химических реакций, протекающих под воздействием высокой температуры в распыляемых над очагом пожара огнетушащих веществах.
