SECTION 2: Hazards identification

Principle Routes of Exposure

Inhalation and skin contact. Signs and Symptoms of May cause irritation and redness to skin upon contact. Exposure: Inhalation of elevated concentrations of vapors may cause irritation to the respiratory tract. Eye contact can cause severe irritation, redness, tearing and blurred vision. Intentional misuse by deliberately concentrating and inhaling vapor may be harmful or fatal.

Medical Conditions Generally Aggravated by Exposure

Pre-existing eye, skin and respiratory disorders may be by Exposure: aggravated by exposure to this product.

Potential chronic health

Repeated or prolonged skin contact may result in defatting of skin and dermatitis. Carcinogenicity: None. SECTION 4: FIRST AID MEASURES First Aid Procedures: For eyes, flush with large amounts of water, lifting upper and lower lids occasionally, get medical attention. For skin contact, wash affected area thoroughly with soap and water. Get medical attention if irritation persists. For inhalation, remove to fresh uncontaminated air. In case of accidental ingestion, do not induce vomiting. Get medical attention and advise the physician of the nature of the material. SECTION 5: FIRE FIGHTING PROCEDURES Suitable Extinguishing Media: Foam, water spray, (fog), carbon dioxide, dry chemical, and vaporizing liquid type extinguishing agents may all be suitable for extinguishing fires involving this product. Water may be ineffective, but should be used to keep fire exposed containers cool. Hazardous Combustion Products: Thermal decomposition products may include hydrocarbons, oxides of carbon, oxides of nitrogen, and aldehydes. Recommended Fire Fighting Wear impermeable protective clothing and self-contained Procedures: breathing apparatus. Unusual Fire and Explosion This product is volatile and gives off invisible vapors. Either the Hazards: liquid or vapor may settle in low areas or travel some distance along the ground or surface to ignition sources where they may ignite or explode. SECTION 6: PRECAUTIONS FOR SAFE HANDLING AND USE Steps to Be Taken in Case Shut off and eliminate all ignition sources. Keep people away. Material is Released or Spilled: Recover free product by adding sand, earth or other suitable absorbent to spill area, and using non-sparking tools, shovel or sweep up and place in suitable container. Minimize breathing vapors. Minimize skin contact. Ventilate confined spaces. Open all windows and doors. Keep product clear of sewers, water, or extensive land areas. Assure conformity with applicable government regulations. Continue to observe precautions for volatile, flammable vapors from absorbed material. Precautions to Be Taken in Keep away from heat, sparks, and open flames. Keep Handling and Storing: containers closed. Containers, even those that have been emptied, can contain explosive vapors. Do not cut, drill, grind, weld or perform similar operations near containers. Static electricity may accumulate and create a fire hazard. Ground fixed equipment. Bond and ground all transfer containers and equipment. SECTION 7: EXPOSURE CONTROLS / PERSONAL PROTECTION Ventilation: Use in a well ventilated area. Respiratory Protection: If personal exposure concentrations cannot be maintained below the appropriate exposure limits using engineering controls, a NIOSH approved respirator may be appropriate based on employer-determined exposure levels. Eye Protection: The use of safety glasses or chemical splash goggles when pouring, mixing or applying this material may be warranted. Skin Protection: The use of chemical resistant gloves when pouring, mixing or applying this material may be warranted. Other: Impervious clothing and boots if appropriate. Work / Hygienic Practices: Wash exposed skin prior to eating, drinking or smoking and at the end of each shift. Wash contaminated clothing prior to reuse.
