3. HAZARD IDENTIFICATION (Continued)
<br />OTHER POTENTIAL HEALTH EFFECTS: Contact of the cold gas with the skin can lead to frostbite or dermatitis (red,
<br />cracked, irkated skin), depending upon concentration and duration of exposure. Contact of the cold gas with the eyes can
<br />cause pain, redness, bums, and severe exposure could cause blindness. Symptoms of frostbite include change in skin
<br />color to white orgrayish-yellow. The pain after contact with cold gas pn quickly subside. Moisture in the air could lead to
<br />the formation of carbonic acid, which can be irritabng to the eyes.
<br />HEALTH EFFECTS OR RISKS FROM F-XPOSURE: An Explanation in Lav Terms. Overexposure to Carbon Dioxide may
<br />cause the following health effects:
<br />ACUTE: Inhaling high concentrations of Carbon Dioxide can lead to coma or death. At low concentrations, inhalation of
<br />Carbon Dioxide can cause nausea, dimness, visual disturbances, shaking, headache, mental confusion, sweating,
<br />increased heartbeat, and elevated blood pressure and respiratory rate. High concentrations of the gas in air may cause
<br />eye irritation or damage.
<br />CHRONIC: Reversible effects on the aad-base balance in the blood, blood pressure, and circulatory system may occur
<br />after prolonged exposure to elevated Carbon Dioxide levels.
<br />TARGET ORGANS: Respiratory system, cardiovascular system, eyes.
<br />Calton Dioxide Solid
<br />EMERGENCY OVERVIEW: Solid Carbon Dioxide (dry ice), is a white, opaque solid which releases cobdess,
<br />gas. This solid sublimates to gas quickly at standard temperatures and pressures, forming a fog in air. As a result, the
<br />main hazards assodated with Carbon Dioxide are related to Carbon Dioxide gas formation and the cold temperature of
<br />the solid and evolved gas. At concenrations between 2 and 10%, Carbon Dioxide pn cause nausea, dizziness,
<br />headache, mental confusion, increased blood pressure and respiratory rate. If the gas concentration reaches 10°~ or
<br />more, suffocation and death can occur within minutes. Contact with the solid can puss freezing of exposed tissue.
<br />Moisture in the air could lead to the formation of carbonic acid which can be irritating to the eyes. Carbon Dioxide is
<br />heavier than air and should not be allowed to accumulate in low Ivina areas.
<br />SYMPTOMS OF OVEREXPOSURE BY ROUTE OF FJCPOSURE: The
<br />most significant routes of overexposure for Carbon Dioxitle are by
<br />inhalation of Carbon Dioxide gas, and skin or eye contact with the solid
<br />or gas. Symptoms of such exposure are as follows:
<br />INHALATION: Carbon Dioxide is an asphyxiant and a powerful cerebral
<br />vasodilator. If the concentraton of Carbon Dioxide reaches t0% or
<br />more, suffopfion can occur rapidly. Inhalation of concentrations
<br />between 2 and 10% can puss nausea, dizziness, headache, mental
<br />confusion, increased blood pressure and respiretory rate. Carbon
<br />Dioxide initially stimulates respiration and then puses respiratory
<br />depression. Inhalation of low concentrations (3-5%) have no known
<br />permanent harmful effects. Symptoms in humans at various levels of
<br />concentration are as follows:
<br />CONCENTRATION SYMPTOMS OF EXPOSURE
<br />1%: Slight increase in breathing rate.
<br />2%: Breathing rate increases to 50% above
<br /> normal; exposure puses headache,
<br /> tiredness.
<br />3%: Breathing increases to twig normal rate and
<br /> becomes labored. Weak narcetic effect.
<br /> Impaired hearing, headache, increase in
<br /> blood pressure and pulse rate.
<br />4-5%: Breathing increases to approximately four
<br /> times normal rata, symptoms of inloxicetion
<br /> become evident; slight choking may be felt.
<br />5-10%: Labored breathing, headache, visual
<br /> impairment, ringing in the ears, impaired
