SECTION 2: Hazards identification

Emergency Overview WARNING! Color Dark Brown Form Viscous Liquid Odor Musty Toxic gases/fumes may be given off during burning or thermal decomposition. Closed container may forcibly rupture under extreme heat or when contents are contaminated with water. Use cold water spray to cool fire-exposed containers to minimize the risk of rupture. Causes respiratory tract irritation. May cause allergic skin reaction. Skin sensitizer. Animal tests and other research indicate that skin contact with MDI can play a role in causing Isocyanate sensitization and respiratory reaction. Causes eye irritation. May cause lung damage. The following ratings are subjective. They are provided as a quick hazard guide only. Read the entire MSDS before using the product.

Potential health effects

Signs, and Symptoms of Exposure

Principle Routes of Exposure

Eye and skin contact, and respiratory tract

Medical Conditions Generally Aggravated by Exposure

Asthma, Respiratory disorders, Skin Allergies, Eczema Acute Eye: Causes irritation and symptoms reddening, tearing, stinging, and swelling. May cause temporary corneal injury. Vapor and aerosol may cause irritation with symptoms of burning and tearing. Chronic Eye: Prolonged vapor contact may cause conjunctivitis. Acute Skin: Causes irritation with symptoms of reddening, itching and swelling. Persons previously sensitized can experience allergic skin reaction with symptoms of reddening, itching, swelling, and rash. Cured material is difficult to remove. Contact with MDI can cause discoloration. Chronic Skin: Prolonged contact can cause reddening, swelling, rash, and in some cases skin sensitization. Animal tests and other research indicate that skin contact with MDI can play a role in causing isocyanate sensitization and respiratory reaction. Acute Inhalation: Diisocyanate vapors may cause irritation of the mucous membranes of the nose, throat or trachea, breathlessness, chest discomfort, difficult breathing and reduced pulmonary function. Air- borne overexposure well above the PEL may result additionally in eye irritation, headache, chemical bronchitis, asthma-like findings or pulmonary edema. Isocyanates have also been reported to cause hypersensitivity pneumonitis, which is characterized by flu-like symptoms, the onset of which may be delayed. Gastrointestinal symptoms include nausea, vomiting and abdominal pain. Chronic Inhalation: As a result of previous repeated overexposures or a single large dose, certain individuals will develop isocyanate sensitization (chemical asthma) which will cause them to react to a later exposure to isocyanate at levels well below the PEL/TLV. These symptoms, which include chest tightness, wheezing, cough, shortness of breath, or asthmatic attack, could be immediate or delayed up to several hours after exposure. Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon exposure to dust, cold air, or other irritants. This increased lung sensitivity can persist for weeks and in severe cases for several years. Chronic overexposure to isocyanates has also been reported to cause lung damage, including a decrease in lung function, which may be permanent. Sensitization may be either temporary or permanent. Prolonged contact can cause reddening, swelling, rash, scaling, or blistering. In those who have developed a skin sensitization, these symptoms can develop as a result of contact with very small amounts of liquid material, or even as a result of vapor-only exposure. Acute Ingestion: May cause irritation; Symptoms may include abdominal pain, nausea, vomiting, and diarrhea. Carcinogenicity: NO CARCINOGENIC SUBSTANCES AS DEFINED BY IARC, NTP AND/OR OSHA.
