May cause irritation of the digestive tract.  Inhalation: Harmful if inhaled. Causes respiratory tract irritation.  Section 4 - First Aid Measures Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.  Skin: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid. Ingestion: Water gargle thoroughly to avoid patients with vomiting, if spontaneous vomiting in patients to ensure that their bodies forward in order to reduce inhalation risk, if the artificial respiration should begin immediately.Call a poison control center. Get medical aid. Inhalation: Immediately move to fresh air. If breathing stop,artificial respiration should begin immediately.Get medical aid. Section 5 - Fire Fighting Measures Extinguishing Media:Use water spray, carbon dioxide, dry chemical powder or media appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes, emits toxic fumes under fire conditions Flash Point: 199.6℃. Section 6 - Accidental Release Measures General Information:Use proper personal protective equipment as indicated in Section 8.  Note: Wear a self contained breathing apparatus and appropriate personal protection. Leakage region ventilation. Fight or remove all ignition sources. To prevent leakage of material into the sewer or confined space. Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements. Large Spill: Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system. Section 7 - Handling and Storage Handling: Approved respirator. Compatible chemical-resistant gloves. Chemical safety goggles, Mechanical exhaust required. Safety shower and eye-bath. Do not breathe dust. Avoid contact with eyes, skin and clothing. Avoid prolonged or repeated exposure wash thoroughly after handling. Storage: Store in a cool, dry place. Store in a tightly closed container. Away from heat, ignition sources and materials compatibility. Near the storage areas have adequate fire extinguishers and spill clean-up equipment. Section 8 - Exposure Controls, Personal Protection Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Personal Protective Equipment: Wear appropriate protective eyeglasses or chemical safety goggles. Wear appropriate protective gloves to prevent skin exposure. Wear appropriate protective clothing to prevent skin exposure. Wear self contained breathing apparatus to avoid inhalation of the product.
