Potential health effects

Eyes severe irritation; tearing skin, discoloration drying; breathing irritation, dizziness, unconsciousness (for solvent). For isocyanates: coughing, irritation of mucous membranes and respiratory tract. SKIN EFFECTS: Slight to moderate irritation; skin sensitizer in guinea pigs. No conclusive evidence has been developed to indicate that Glisten PC is carcinogenic, teratogenic or that it causes reproductive effects in animals or humans. Active resin in Glisten PC has been reported by NIOSH to be mutagenic to Salmonella Typhimurium bacteria in the presence of a mammalian liver activation system. There is not full agreement in the scientific community on the significance of these Ames test results and their relationship to human safety in assessing the risk of cancer in man. Eye: HUMAN EFFECTS OF OVEREXPOSURE: Liquid, vapors, or aerosols are irritating to the eyes and can cause lachrymation (tearing effect). Corneal damage can occur; however, indications are that the damage is reversible and does not result in permanent injury. Skin: HUMAN EFFECTS OF OVEREXPOSURE: Glisten PC reacts with skin protein and tissue moisture and can cause localized irritation as well as discoloration. Prolonged contact could produce reddening, swelling, or blistering and, in some individuals, skin sensitization resulting in dermatitis. Inhalation: HUMAN EFFECTS OF OVEREXPOSURE: Inhalation of Glisten PC vapors in concentrations above 0.02 ppm can produce irritation of the mucous membranes in the respiratory tract, running nose, sore throat, productive cough and a reduction of lung function. Extensive exposures to concentrations well above the TLV could lead to bronchitis, bronchial spasm and pulmonary edema. These effects are usually reversible. However, due to low volatility, high exposures are not anticipated except if the material is overheated or sprayed as an aerosol into the air. Hypersensitivity pneumonitis has also been reported. Another type of response is hyperreactivity or hypersensitization. Persons with a preexisting unspecific bronchial hyperreactivity or persons with a specific isocyanate hypersensitivity (as a result of previous repeated overexposure or a single large dosage)will respond to small isocyanate concentrations at levels well below the TLV of 0.02 ppm. Symptoms could be immediate or delayed and include chest tightness, respiratory distress or asthmatic attack. Ingestion: HUMAN EFFECTS OF OVEREXPOSURE: Ingestion could result in irritation and some corrosive action in the mouth, stomach tissue and digestive tract. However, it is not considered a common occupational route of exposure.
