MATERIALS WITH WHICH SUBSTANCE IS INCOMPATIBLE: Carbon Dioxide will ignite and explode when heated with powdered aluminum, beryllium, cerium alloys, chromium, magnesium -aluminum alloys, manganese, thorium, titanium, and zirconium. In the presence of moisture, Carbon Dioxide will ignite with cesium oxide. Metal acetylides will also ignite and explode on contact with Carbon Dioxide. HAZARDOUS POLYMERIZATION: Will not occur, however Carbon Dioxide acts to catalyze the polymerization of acryladehyde and aziridine. CONDITIONS TO AVOID: Avoid exposing cylinders of Carbon Dioxide to extremely high temperatures, which could cause the cylinders to rupture or burst. Do not store the solid form of Carbon Dioxide in gas-tight containers, which could also cause over -pressurization and rupture of the container. PART IV Is there any other useful information about this material? 11. TOXICOLOGICAL INFORMATION TOXICITY DATA: Carbon Dioxide is an asphyxiant gas, which has physiological effects at high concentrations. The following toxicological data are available for Carbon Dioxide. LCLo (inhalation, human) = 9 pph/5 minutes. LCLo (inhalation, mammal) = 90000 ppm/5 minutes. TCLo (inhalation, rat) = 6 pph/24 hours; reproductive and teratogenic effects. SUSPECTED CANCER AGENT: Carbon Dioxide is not found on the following lists: FEDERAL OSHA Z LIST, NTP, CAUOSHA, IARC, and therefore is not considered to be, nor suspected to be a cancer-causing agent by these agencies. IRRITANCY OF PRODUCT: Contact with rapidly expanding gases can cause frostbite and damage to exposed skin and eyes. Due to the formation of carbonic acid, this gas mixture can be slightly irritating to contaminated eyes. SENSITIZATION OF PRODUCT: Carbon Dioxide is not a sensitizer after prolonged or repeated exposures. REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of Carbon Dioxide on the human reproductive system. Mutagenicity: Carbon Dioxide is not expected to cause mutagenic effects in humans. Embryotoxcity: Carbon Dioxide has not been reported to cause embryotoxic effects; see next paragraph for information. Teratogenicity: Carbon Dioxide is not expected to cause teratogenic effects in humans. Clinical studies involving test animals exposed to high concentrations of Carbon Dioxide indicate teratogenic effects (e.g., cardiac and skeletal malformations, stillbirths). Reproductive Toxicity: Carbon Dioxide is not expected to cause adverse reproductive effects in humans. Studies involving test animals exposed to high concentrations of Carbon Dioxide indicate reproductive effects (e.g. changes in testes). A muta en is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a chemical which causes damage to a developing fetus, but the damage does not propagate across generational lines. A reproductive toxin is any substance which interferes in any way with the reproductive process. MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Disorders involving the `Target Organs" (see Section 3, Hazard Information) may be aggravated by Carbon Dioxide overexposure. RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce overexposure. BIOLOGICAL EXPOSURE INDICES (BEls): Currently, Biological Exposure Indices (BEIs) are not applicable for Carbon Dioxide. 12. ECOLOGICAL INFORMATION ENVIRONMENTAL STABILITY: Carbon Dioxide occurs naturally in the atmosphere. The gas will be dissipated rapidly in well -ventilated areas. The following environmental data are applicable to Carbon Dioxide. CARBON DIOXIDE: Food chain concentration potential: None. Biological Oxygen Demand: None EFFECT OF MATERIAL ON PLANTS or ANIMALS: Any adverse effect on animals would be related to Carbon Dioxide overexposure and oxygen -deficient environments. No adverse effect is anticipated to occur to plant -life, except for frost produced in the presence of rapidly expanding gases. EFFECT OF CHEMICAL ON AQUATIC LIFE: The following aquatic toxicity data are available for Carbon Dioxide. CARBON DIOXIDE: Aquatic toxicity: 100-200 mg/I/no time specified/various organisms/fresh water. Waterfowl toxicity: Inhalation 5-8%, no effect. ('ARRnm ninyinp: - (_nL 11AC1)Cmnr-iieeCKIT,4mmnim
