Chemstar strives to maintain high purity and production quality. Calcium oxide is NOT listed by NTP, IARC, or OSHA as containing carcinogens; however, it contains detectable amounts of chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. I` SECTION III—PHYSICAL AND CHEMICAL CHARACTERISTICS Appearance and Odor: White solid;Odorless. Chemstar High Calcium Lime is available as lump, pebble, granules,.or crushed form. Screened material is available in a range of particle sizes. Melting Point: 4676 F/2580 C Particle Specific Gravity: 3:2- Bulk Density:55-60lbs/cu.ft.

SECTION IV---FIRE AND EXPLOSION HAZARD DATA W ;a Special Fire Fighting Procedures: In large amounts, lime in contact with water, steam or acids, will generate sufficient heat to ignite } f wood and other materials. In small amounts, the presence of lime in a fire does not hinder-the use of any standard extinguishing medium. Wear seff-dontained breathing apparatus approved by NIOSH. Protect eyes from dust. - - ' Ffashpoint:Not Flammable Flammable Limits:NIA Extinguishing Media:Not Flammmable Explosion Potential: None SECTION V—HEALTH, FIRST AID AND MEDICAL DATA Threshold Limit Value(TLV): 2 mg/cu.m. Calcium oxide is a strongly alkaline material. Contact with skin and eyes will cause irritation and possible severe corrosion damage. Inhalation of dust may cause coughing, sneezing, or inflammation of the respiratory passages. While short term exposure and irritation are generally without permanent effects, untreated contact and irritation can cause serious chemical and thermal burns and permanent scarfing. Prevention of contact and exposure under good working conditions is much preferred to first aid after injury. See Section Vll below. Calcium oxide is NOT listed by NTP, IARC,or OSHA as containing carcinogens;however, it contains detectable amounts of 4hemicals known to the State of California to cause cancer, birth defects.or other reproductive harm. A. ! FIRST AID ' 4 T -i4'4- .i .. ." I Inhalation: Remove from exposure to dust and get prompt medical help. ` Eye Contact: Wash eyes immediately with running water for 15 minutes, including under eyelids. Get prompt medical. attention! Skin Contact: Wash exposure area with large amounts of water. Remove and wash contaminated clothing.v Ingestion: Get medical attention..Give large amounts of water to dilute,but do"not induce vomiting.
