Excessive exposure will produce serious, possibly irreversible pulmonary injury. If breathing has stopped, artificial respiration must be promptly applied. If breathing is labored and oxygen inhalation equipment is available, oxygen should be administered by trained personnel. Obtain medical attention immediately. Component A should be kept away from caustic solutions, tertiary amines, and water, to prevent rapid polymerization and accompanying generation of heat and gasses.
Dangerous pressures can develop in closed containers.
Open the containers carefully, allowing any built-up pressure to be relieved slowly and safely. Solvent manufacturer's precautions must be observed. A sprinkler system, water spray, carbon dioxide or dry chemical extinguisher may be used for extinguishing fires involving liquid components. Fire fighters should wear self-contained breathing apparatus. Exposed foam insulation in an interior area presents an unreasonable fire risk.
