Demonstration of Biodegradable, Environmentally Safe, Non-Toxic Fire SuppressionLiquids

摘要

This report includes methods, as developed by the United States Department ofAgriculture, for demonstrating environmental safety and toxicity of these agents. NIST investigated smoke generation during suppression and conducted a broad-based study on fire suppression effectiveness including laboratory scale experiments and large-scale fire suppression expirements. The following characteristics were investigated at laboratory scale; specific heat, drop size, cooling and penetration, contact angle, mass retention and igniton inhibition. Large-scale experiments were used to examine the suppression effectiveness of the agents on wood crib, tire, heptane, gasoline, magnesium and titanium fires.
