SIDE A SIDE B Overview • Symptoms respiratory sensitization: Animal toxicity:  Irritation to eyes, nose, throat and lungs • Oral, LD 50 NE  Dryness of throat • Dermal, LD 50 NE  Chest tightness • Inhalation, LC 50 (4 hrs) NE  Difficulty breathing • Aquatic, LC 50 (24 hrs) NE • Onset of symptoms may be delayed several hours • Eyes NE after exposure • Skin NE • Hyper-reactive response to minimal concentrations of MDI may develop in sensitized persons Inhalation • Respiratory irritant • Possible throat irritation • Repeated inhalation of vapor or aerosol at levels • At room temperature, vapor above the occupational exposure limit could cause inhalation is not considered respiratory sensitization hazardous, vapors may cause • Symptoms: dizziness, tremors, arrhythmia and cardiac arrest Skin • Moderate irritant • Amine catalyst will cause • Repeated or prolonged contact may cause skin irritation to the skin after sensitization prolonged contact • Respiratory sensitization can occur from skin contact Eye Contact • Irritant • Slight irritant Ingestion • May cause irritation of Gastro-intestinal tract • This is not considered a • Based on oral LD50, product practically non-toxic by common occupational route of ingestion exposure, and no observable effects have been demonstrated Chronic Study: indicated that in absence of prolonged exposure to • Threshold limit Value (ACGIH): effects high concentrations leading to chronic irritation and lung No TLV has been established damage, it is highly unlikely that tumor formation will for this product as a system occur. There are reports that chronic exposure may result • OSHA: same as above in permanent decrease in lung function. Study: groups of rats exposed 6 hrs/day, 5 days / week for a lifetime to atmospheres of respirable polymeric MDI aerosol.
