SECTION 2: Hazards identification

Emergency Overview WARNING! EYE, SKIN, LUNG IRRITANT. May cause eye irritation. May cause skin irritation. May cause allergic skin reaction. Skin Sensitizer. May cause allergic respiratory reaction. Harmful if inhaled. May cause lung injury. Respiratory sensitizer. Lung damage and respiratory sensitization may be permanent. May cause central nervous system effects. Keep upwind of spill. May cause anesthetic effects. Pressurized Containers: storage temperature should not exceed 120F (49C) in order to avoid excessive pressure build-up and possible release of contents. MDI will react with water to form CO2 and water insoluble polyureas.

Potential health effects

The primary adverse health effects of this product are related to the polymeric isocyanate (MDI) component, and, to a lesser degree, the fluorinated hydrocarbon (134a) component. Therefore, use in a well ventilated area and with certified respiratory protection to avoid exceeding exposure limits listed in Section 8 of this MSDS. Entry Route: Effects of Overexposure Inhalation: May irritate mucous membranes. Can cause runny nose, sore throat, coughing, chest discomfort, shortness of breath, wheezing, and reduced lung function. Extensive overexposure can lead to respiratory symptoms like bronchitis, bronchial spasm, and pulmonary edema (fluid in the lungs). These symptoms could be immediate or delayed up to several hours after exposure. These effects are usually reversible, but increased lung sensitivity can persist for a longer period of time. Chronic overexposure to diisocyanates can cause permanent damage. May cause allergic respiratory reactions for individuals sensitized to MDI. Overexposure to 1,1,1,2 - Tetrafluoroethane may cause lightheadedness, headaches, or lethargy. Persons with cardiac arrhythmia are more susceptible to increased medical risk from severe exposure. TWO-COMPONENT LOW PRESSURE A-COMPONENT ISSUE DATE March 2005 LAST REV February 2012 PAGE 2 OF 7 Eyes: May be irritating to eyes. Symptoms of irritation can include reddening, tearing, swelling, or stinging. May cause temporary corneal injury. Chronic overexposure may cause conjunctivitis. Skin: May cause localized irritation, reddening or swelling. May cause an allergic reaction. Prolonged or repeated exposure may lead to sensitization and/or contact dermatitis. Ingestion: May cause irritation of mucous membranes in the mouth and digestive tract. Symptoms may include abdominal pain, nausea, vomiting, and diarrhea. Small amounts are unlikely to cause symptoms or injury. If accidental contact occurs, follow the appropriate first aid procedure described in Section 4 of this MSDS.
