Do not expose polyurethane foam to welding, smoking materials, naked lights, open flames, space heaters, burning operations, other ignition sources, or other heat or flames. Once ignited, polyurethane will burn rapidly, releasing great heat and consuming oxygen at a high rate in an enclosed space. Deficiency of oxygen will present a danger of suffocation to occupants. Hazardous gases and smoke released by the burning foam can be incapacitating or fatal to human beings if inhaled.
Precautions to be Taken in Handling and Storage: Maintain adequate sprinkler protections where large volumes of product are kept: i.e., warehouse, fabrication areas, storage rooms, etc. See your fire insurance carrier for specific recommendations.
