Expanding Foam

SECTION 2: Hazards identification

EMERGENCY OVERVIEW IMMEDIATE CONCERNS: DANGER! Extremely flammable liquid and vapor. Vapor may cause flash fire. May cause eye, skin, nose, throat and respiratory tract irriation. May cause an allergic skin reaction. Harmful if inhaled. Contents under pressure, storage temperature should not exceed 120oF (49oC) in order to avoid excessive pressure build up and possible container rupture. Vapor reduces oxygen available for breathing. May cause lung injury. Respiratory sensitizer. May cause central nervous system effects. May cause liver damage. Toxic gases/fumes may be given off during burning.

Potential health effects

EYES: May cause eye irritation. Foam contact can cause physical damage due to adhesive character. Vapors may cause slight temporary corneal injury. SKIN: May cause localized irritation, reddening or swelling. Prolonged or repeated exposure may lead to sensitization. May cause and allergic reaction. Prolonged skin exposure is unlikely to result in absorption of harmful amounts. Foam will stick to the skin causing irritation upon removal. INGESTION: May cause irritation of mucous membranes in the mouth and digestive tract. Small amounts swallowed as a result of normal handling are not likely to cause unjury; swallowing large amounts may cause injury. INHALATION: Vapors may irritate mucous membranes with tightness in chest, coughing, or allergic asthma-like sensitivity. Extensive overexposure can lead to respiratory symptoms such as asthma and pulmonary edema. These diseases may be aggravated by prolonged exposure. Excessive exposure may cause irritation to upper respiratory tract and lungs. Overexposure to the hydrocarbon gas mixture may cause lightheadedness, headaches, or lethargy. Persons with cardiac arrhythmia may be at increased risk in severe exposure. In poorly ventilated areas, vapor can easily accumulate and can cause unconsciousness and death due to displacement of oxygen. Excessive exposure may aggravate pre-existing conditions such as asthma, emphysema, bronchitis, etc. COMMENTS HEALTH: The primary adverse health effects of this product are related to the individual components that make up the mixture; polymeric isocyanate (pMDI) component and the liquefied petroleum gas (Hydrocarbon, HC) component. These products should be used in a well ventilated area to avoid exceeding the exposure limits of these components (listed in Section 8 of this MSDS). If used indoors, mechanical ventilation or exhaust should be provided during use and until product is cured.
