FLAMMABLE LIQUID AND VAPOR. \n\nSAF-T-DATA(tm) Ratings (Provided here for your convenience) \n----------------------------------------------------------------------------------------------------------- \nHealth Rating: 3 - Severe (Poison) \nFlammability Rating: 2 - Moderate \nReactivity Rating: 2 - Moderate \nContact Rating: 4 - Extreme (Corrosive) \nLab Protective Equip: GOGGLES & SHIELD; LAB COAT & APRON; VENT HOOD; PROPER GLOVES; CLASS B EXTINGUISHER \nStorage Color Code: Red (Flammable) \n----------------------------------------------------------------------------------------------------------- \n\nPotential Health Effects \n---------------------------------- \n\nInhalation: \nInhalation of concentrated vapors may cause serious damage to the lining of the nose, throat, and lungs. Breathing difficulties may occur. Neither odor nor degree of irritation are adequate to indicate vapor concentration. \nIngestion: \nSwallowing can cause severe injury leading to death. Symptoms include sore throat, vomiting, and diarrhea. Ingestion of as little as 1.0 ml has resulted in perforation of the esophagus. \nSkin Contact: \nContact with concentrated solution may cause serious damage to the skin. Effects may include redness, pain, skin burns. High vapor concentrations may cause skin sensitization. \nEye Contact: \nEye contact with concentrated solutions may cause severe eye damage followed by loss of sight. Exposure to vapor may cause intense watering and irritation to eyes. \nChronic Exposure: \nRepeated or prolonged exposures may cause darkening of the skin, erosion of exposed front teeth, and chronic inflammation of the nose, throat, and bronchial tubes. \nAggravation of Pre-existing Conditions: \nPersons with pre-existing skin disorders or eye problems, or impaired respiratory function may be more susceptible to the effects of the substance. \n\n--------------------------------------------------------------------------------\n\n4.
