FIELD: fire engineering.
SUBSTANCE: fire extinguishing agent contains humectant and water. The humectant is made of "ОСА-1" fire retarder, obtained using interaction between carbamide-formaldehyde concentrate with ammonia water and carbamide, and subsequent neutralisation of reaction mix by phosphoric acid up to pH 6.0 - 6.8. Mass ratio of "ОСА-1" and water components is (1-8):100.
EFFECT: decrease of fire extinguishing agent consumption and time needed for fire suppression.
