If breathing is difficult,trained personnel should administer emergency oxygen if advised to do so by the POISON CENTER/doctor. Eye Contact Rinse eyes cautiously with lukewarm,gently flowing water for several minutes,while holding the eyelids open.Remove contact lenses,if present and easy to do.Continue rinsing for a duration of 15-20 minutes.Take care not to rinse contaminated water into the unaffected eye or onto the face. Skin Contact Take off immediately all contaminated clothing,shoes and leather goods(e.g.watchbands,belts).Wash with plenty of lukewarm,gently flowing water for a duration of 15-20 minutes. If skin irritation or rash occurs:Wash contaminated clothing before re-use or discard. Ingestion Do NOT induce vomiting. If vomiting occurs naturally,lie on your side,in the recovery position. If exposed/If you feel unwell/If concerned: Most Important Symptoms and Effects, Both acute and Delayed Isocyanate vapors or mist at concentrations above the exposure limits or guidelines can irritate(burning sensation)the mucous membranes in the respiratory tract(nose,throat,lungs)with symptoms of runny nose,sore throat,coughing,chest discomfort,shortness of breath and reduced lung function(breathing difficulty). Persons with a preexisting,nonspecific bronchial hyperreactivity can respond to concentrations below the exposure limits or guidelines with similar symptoms as well as asthma attack or asthma-like symptoms. Exposure well above the exposure limits or guidelines may lead to bronchitis,bronchial spasm and pulmonary edema(fluid in lungs). Chemical or hypersensitivity pneumonitis,with flu-like symptoms(e.g.fever,chills),has also been reported.These symptoms can be delayed up to several hours after exposure.These effects are usually reversible. Causes skin irritation with symptoms of reddening, itching,and swelling.Can cause sensitization.Persons previously sensitized can experience allergic skin reaction with symptoms of reddening,itching,swelling,and rash.Cured material is difficult to remove. May cause eye irritation with symptoms of reddening,tearing,stinging,and swelling.Vapor or aerosol may cause irritation with symptoms of burning and tearing. May cause irritation of the digestive tract;Symptoms may include abdominal pain,nausea,vomiting,and diarrhea. Indication of Any Immediate Medical Attention and Special Treatment Needed Specific antidotes or neutralizers to isocyanates do not exist.Treatment should be supportive and based on the judgement of the physician in response to the reaction of the patient. SECTION 5) FIRE-FIGHTING MEASURES Suitable Extinguishing Media Dry chemical,carbon dioxide,water spray,fog or foam. Unsuitable Extinguishing Media Do NOT use water jet. Specific Hazards in Case of Fire Fire will produce irritating and toxic gases. Decomposition products may include carbon oxides,nitrous gases,isocyanate vapors. Fire-Fighting Procedures Stop spill/release if it can be done safely.Move undamaged containers from immediate hazard area if it can be done safely.Cool containers with flooding quantities of water until well after fire is out.Caution should be exercised when using water or foam as frothing may occur,especially if sprayed into containers of hot,burning liquid.Dispose of fire debris and contaminated extinguishing water in accordance with official regulations. Special Protective Actions Wear positive pressure self-contained breathing apparatus(SCBA).Structural firefighter protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.
