Oxygen levels below 19.5% may cause asphyxia. Exposure to carbon dioxide gas can cause nausea and respiratory problems. High concentrations may cause vasodilation leading to circulatory collapse. Contact with solid product may cause frostbite or freeze burns in exposed tissues.

Carcinogenicity: -- NTP: No IARC: No OSHA: No

Contact with product may cause frostbite or cryogenic "burns.

Contact with product may cause frostbite or cryogenic "burns". Frostbite effects are a change in color of the skin to gray or white, possibly followed by blistering. Skin may become inflamed and painful.

Contact with product may cause frostbite or cryogenic "burns".

Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concentrations causes rapid circulatory insufficiency leading to coma and death. Asphyxiation is likely to occur before the effects of carbon dioxide overexposure. Chronic, harmful effects are not known from repeated inhalation of low concentrations. Low concentrations of carbon dioxide cause increased respiration and headache.

Effects of oxygen deficiency may include: rapid breathing, diminished mental alertness, impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death.

Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.

Never introduce oil or ointment into the eyes without medical advice! In case of freezing or cryogenic "burns" by rapidly evaporating liquid. DO NOT WASH THE EYES WITH HOT OR EVEN TEPID WATER! Remove victim from the source of contamination. Open eyelids wide to allow liquid to evaporate. If pain is present, refer the victim to an ophthalmologist for further treatment and follow up. If the victim cannot tolerate light, protect eyes with a light bandage or handkerchief.

Remove contaminated clothing and flush affected area with cold water and soap. DO NOT USE HOT WATER. A physician should see the patient promptly if the cryogenic "burn" has resulted in blistering of the skin or deep tissue freezing or if frostbite has occurred. Treat the "burn" in a similar manner as a thermal burn.

A physician should see the patient promptly if the cryogenic "burn" has resulted in blistering of the skin or deep tissue freezing or if frostbite has occurred.

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO CARBON DIOXIDE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an uncontaminated area, given mouth-to-mouth resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive.

None. Nonflammable.

Avoid contact with spilled product. Personnel in area should use insulated gloves and other protective clothing to prevent contact. If spilled in confined area, provide ventilation to prevent buildup of carbon dioxide gas.

Non-Hazardous.

Dry carbon dioxide can be handled in most common structural materials. Moist carbon dioxide is generally corrosive by its formation of carbonic acid. For applications with moist Carbon Dioxide, 316, 309 and 310 stainless steels may be used as well as Hastelloy (R) A, B, & C, and Monel (R). Ferrous Nickel alloys are slightly susceptible to corrosion. At normal temperatures carbon dioxide is compatible with most plastics and elastomers.

Use only in well-ventilated areas. Carbon dioxide vapor is heavier than air and will accumulate in low areas.

Carbon dioxide solid should be stored in insulated containers equipped with loose fitting lids which will allow escape of vapor caused by sublimation. Do not store in subsurface or enclosed areas. Locate the insulated storage container in an area where there is adequate ventilation so as to prevent the accumulation of carbon dioxide vapors/gas above exposure limits. DO NOT PUT DRY ICE IN A CLOSED CONTAINER WHERE EVOLVED GAS CANNOT ESCAPE! Remove scrap solid (snow or dry ice) to a hood with forced ventilation or take to a remote outside location and allow to sublime.

Protect containers from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and emergency exits.

IDLH (Carbon Dioxide): 50,000 ppm

Refer to individual state or provincial regulations, as applicable, for limits which may be more stringent than those listed here.

Use local exhaust to prevent accumulation of high concentrations so as to reduce the oxygen level in the air to less than 19.5% and the carbon dioxide concentration below the exposure limit.

Safety goggles or glasses as appropriate for the job. A faceshield is recommended for handling cryogenic material.

Protective gloves of any material appropriate for the job. Insulated gloves are recommended for cryogenic materials.

Positive pressure air line with full-face mask and escape bottle or self-contained breathing apparatus should be available for emergency use.

Safety shoes.

Stable

Certain reactive metals, hydrides, moist cesium monoxide, or lithium acetylene carbide diammino may ignite. Passing carbon dioxide over a mixture of sodium peroxide and aluminum or magnesium may explode.

Carbon monoxide and oxygen when heated above 3092^oF (1700^oC). Carbonic acid is formed in the presence of moisture.

Will not occur.

Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals.

Exposure of female rats to 60,000 ppm carbon dioxide for 24 hours has produced toxic effects to the embryo and fetus in pregnant rats. Toxic effects to the reproductive system have been observed in other mammalian species at simialr concentrations.

Carbon dioxide is the most powerful cerebral vasodilator known. Inhaling large concentrations causes rapid circulatory insufficiency leading to coma and death. Chronic, harmful effects are not known from repeated inhalation of low (3 to 5 molar %) concentrations.

No data given.

Allow to sublime (evaporate) in a well ventilated area.

Note: Only regulated as a hazardous material if shipped by air or water.

Acute Health Hazard

Compressed gas cylinders shall not be refilled without the express written permission of the owner. Shipment of a compressed gas cylinder which has not been filled by the owner or with his/her (written) consent is a

violation of transportation regulations.
