DTM URETHANE MASTIC ACTIVATOR

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: May cause allergic respiratory reaction. Causes eye burns. Causes eye irritation. May cause allergic skin reaction. Combustible liquid and vapor. EFFECTS OF OVEREXPOSURE - EYE CONTACT: Corrosive. Will cause eye burns and permanent tissue damage, including blindness. EFFECTS OF OVEREXPOSURE - SKIN CONTACT: Causes skin irritation. Allergic reactions are possible. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. EFFECTS OF OVEREXPOSURE - INHALATION: Diisocyanate or polyisocyanate vapors or mist at concentrations above the exposure limits or guideline can irritate the mucous membranes in the respiratory tract. With symptoms of runny nose, sore throat, shortness of breath and reduced lung function. Persons with a preexisting nonspecific bronchial hyper reactivity. As a result of previous repeated overexposures or a single large dose, certain individuals may develop sensitization to diisocyanates, or polyisocyanates that may cause them to react to a later exposure to diisocyanates, or polyisocyanates at levels well below the exposure limits or guidelines. The symptoms which can include chest tightness, wheezing, cough, shortness of breath or asthmatic attack could be delayed up to several hours after exposure Extreme asthmatic reactions could be life threatening. Sensitization can be permanent. Chronic overexposure to diisocyanates has also been reported to cause lung damage that may be permanent. High vapor concentrations are irritating to the eyes, nose, throat and lungs. May cause allergic respiratory reaction. EFFECTS OF OVEREXPOSURE - INGESTION: No Information EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS: Contains a Cobalt compound. IARC lists Cobalt and Cobalt compounds as as possible human carcinogens (group 2B). However, there is inadequate evidence of the carcinogenicity of cobalt and cobalt compounds in humans and limited evidence in experimental animals.
