2 All hazard information pertinent to this product has been provided in thisMaterial SAFETY Data SHEET , per the requirements of the OSHA Hazard CommunicationStandard (29 CFR ) and State equivalents = Not EstablishedC = Ceiling LimitSee Section 16 for Definitions of Terms : all WHMIS required information is included. It is located in appropriate sections based on the ANSI dioxide - CO2 MSDSEFFECTIVE DATE: JUNE 1, 1998 PAGE 2 OF 93. HAZARD IDENTIFICATIONEMERGENCY OVERVIEW: carbon dioxide is a colorless, odorless gas, or a colorless, odorless liquid in ahigh-pressure container. Over-exposure to carbon dioxide can increase respiration and heart rate, possiblyresulting in circulatory insufficiency, which may lead to coma and death. At concentrations between 2 and10%, carbon dioxide can cause nausea, dizziness, headache, mental confusion, increased blood pressureand respiratory rate.

3 Exposure to carbon dioxide can also cause asphyxiation, through displacement ofoxygen. If the gas concentration reaches 10% or more, suffocation can occur within minutes. The liquid willrapidly boil to the gas at standard temperatures and pressures. Contact with the cold gas can cause freezingof exposed tissue. Moisture in the air could lead to the formation of carbonic acid which can be irritating tothe eyes. All forms of carbon dioxide are OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant routes of over-exposurefor this gas are by inhalation, and skin or eye contact. Symptoms of such exposure are as follows:INHALATION: carbon dioxide is an asphyxiant and a powerful cerebral vasodilator. If the concentration ofCarbon dioxide reaches 10% or more, suffocation can occur within minutes. At concentrations between 2 and10%, carbon dioxide can cause nausea, dizziness, headache, mental confusion, increased blood pressure andrespiratory rate.

4 carbon dioxide initially stimulates respiration and then causes respiratory depression. Highconcentrations result in narcosis. Repeated inhalation of low concentrations (3-5%) have no known permanentharmful effects. Symptoms in humans are as follows:CONCENTRATIONEFFECT1%Slight increase in breathing rate increases to 50% above normal level. Prolonged exposure can causeheadache, increases to twice normal rate and becomes labored. Weak narcotic hearing, headache, increase in blood pressure and pulse increases to approximately four times normal rate, symptoms of intoxicationbecome evident and slight choking may be sharp odor noticeable. Very labored breathing, headache, visualimpairment and ringing in the ears. Judgment may be impaired, followed within minutesby loss of occurs more rapidly above 10% level.

HAZARD IDENTIFICATION (Continued)INHALATION (continued): High concentrations of this gas can also cause an oxygen-deficient , the asphyxiating properties of carbon dioxide will be reached before oxygen-deficiency is a WITH SKIN or EYES: Contact of the cold gas with the skin can lead to frostbite or dermatitis (red,cracked, irritated skin), depending upon concentration and duration of exposure.

6 Contact of the cold gas, or soliddry ice with the eyes can cause pain, redness, burns, and severe exposure could cause POTENTIAL HEALTH EFFECTS: Symptoms of frostbite include change in skin color to white orgrayish-yellow. The pain after contact with cold gas can quickly subside. Moisture in the air could lead to theformation of carbonic acid, which can be irritating to the EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to CarbonDioxide may cause the following health effects:ACUTE: carbon dioxide is an asphyxiant and a powerful cerebral vasodilator. Inhaling large quantities causesrapid circulatory insufficiency, which can lead to coma or death. At low concentrations, inhalation of CarbonDioxide can cause nausea, dizziness, visual disturbances, shaking, headache, mental confusion, sweating,increased heartbeat, and elevated blood pressure and respiratory rate.

7 High concentrations of the gas in air maycause eye irritation. Contact with the eyes can cause damage to the retinal ganglion : There are currently no known adverse health effects associated with chronic exposure to this ORGANS: Respiratory system, central nervous system, FIRST-AID MEASURESRESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THISPRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus equipment should be victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygenand/or cardio-pulmonary resuscitation, if EXPOSURE: Remove any clothing that may restrict circulation to any frozen area. Do not rub frozenparts as tissue damage may occur. As soon as practicable, place any affected area in warm water bath whichhas a temperature that does not exceed 105 F (40 C).

8 NEVER USE HOT WATER. NEVER USE DRY area of frostbite is extensive, remove clothing while showering with warm water. If warm water is not available,or is impractical to use, wrap the affected parts gently in blankets. Alternatively, if the fingers or hands arefrostbitten, place the affected area of the body in the armpit. Encourage victim to gently exercise the affectedpart while being warmed. Seek immediate medical tissue is painless and appears waxy, with a possible yellow color. Frozen tissue will become swollen,painful and prone to infection when thawed. If the frozen part of the body has been thawed by the time medicalattention has been obtained, cover the area with a dry sterile dressing and a large bulky protective EXPOSURE: If irritation of the eye develops after exposure to gas, open victim's eyes while under gentlerunning water.

9 Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 medical assistance immediately, preferably an (s) must be taken for medical attention. Rescuers should be taken for medical attention, if copy of label and MSDS to physician or other health professional with victim(s).5. fire -FIGHTING MEASURESFLASH POINT: Not TEMPERATURE: Not LIMITS (in air by volume, %):Lower (LEL): Not (UEL): Not EXTINGUISHING MATERIALS: carbon dioxide is commonly used as an extinguishing agent for Class Band Class C fires. Use extinguishing media appropriate for the surrounding dioxide - CO2 MSDSEFFECTIVE DATE: JUNE 1, 1998 PAGE 4 OF 95. fire -FIGHTING MEASURES (ContinuedUNUSUAL fire AND EXPLOSION HAZARDS: carbon dioxide does not burn; however, containers, wheninvolved in fire , may rupture or burst in the heat of the fire .)

10 Dusts of various reactive metals ( , magnesium,zircon, titanium alloys), are readily ignited and explode in the presence of carbon dioxide . In the presence ofmoisture, cesium oxide ignites on contact with carbon dioxide . Metal acetylides or hydrides will also ignite carbon dioxide will vaporize rapidly when accidentally released, forming an oxygen-deficient vapor , if large concentrations of carbon dioxide gas are present, the water vapor in the surrounding air willcondense, creating a dense fog . Evacuate the surrounding area; visibility may be obscured in such a vaporcloud making it difficult to find fire exits or equipment. Pressure in a high pressure container can build-up due toheat and it may rupture if pressure relief devices should fail to function. Contact with cold, gaseous or solidCarbon dioxide may cause Sensitivity to Mechanical Impact: Not Sensitivity to Static Discharge: Not fire -FIGHTING PROCEDURES: Structural fire -fighters must wear Self-Contained BreathingApparatus and full protective ACCIDENTAL RELEASE MEASURESLEAK RESPONSE: Evacuate immediate area.
