Foams Fogging

SAFETY PROFILE Poison by intravenous route. Questionable carcinogen with experimental neoplastigenic data by skin contact. Moderately flammable when exposed to heat or flame. To tight tire, use foam, fog, dr f chemical, water mist or spray, multipurpose dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. 

DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE Poison by ingestion, inhalation, subcutaneous, intravenous, and intraperitoneal routes. Moderately toxic by skin contact, A severe eye and skin irritant. Human mutation data reported. Questionable carcinogen with experimental neoplastigenic data. Flammable when exposed to heat, flame, or oxidants. To fight fire, water may be used to blanket fire foam, fog, mist, dry chemical. See also other cresol entries and PHENOL. 

SAFETY PROFILE Moderately toxic by ingestion, inhalation, and skin contact. A skin and eye irritant. Flammable liquid when exposed to heat or flame can react with oxidizing materials. To fight fire, use CO2, dry chemical, alcohol foam, fog, and mist. When heated to decomposition it emits...

Nonreactive additive flame retardants dominate the flexible urethane foam field. However, auto seating appHcations exist, particularly in Europe, for a reactive polyol for flexible foams, Hoechst-Celanese ExoHt 413, a polyol mixture containing 13% P and 19.5% Cl. The patent beHeved to describe it (114) shows a reaction of ethylene oxide and a prereacted product of tris(2-chloroethyl) phosphate and polyphosphoric acid. An advantage of the reactive flame retardant is avoidance of windshield fogging, which can be caused by vapors from the more volatile additive flame retardants. 

Isophthahc acid dust forms explosive mixtures with air at certain concentrations. These concentrations and other information on burning and explosiveness of isophthahc acid dust clouds are given in Table 27 (40,41). Fires can be extinguished with dry chemical, carbon dioxide, water or water fog, or foam. 

For troubleshooting suspected foam problems, vaporize samples of feed and bottoms to look for suspended solids. Also, one can look for the Tyndall effect as described in the section on condenser fogging.
