It is also <br /> physiologically aellve, affecting circulation and breathing. Moderate concentrations may cause <br /> headache, drowsiness, dizziness, stinging of the nose and throat, excitation, rapid breathing <br /> and heart rate, excess salivation, vomiting, and unconsciousness, Lack of oxygen can kill. <br /> Carbon dioxide is an asphyxiant. It initially stimulates respiration and then causes respiratory <br /> depression. High concentrations result In narcosis. Symptoms In humans are as follows: <br /> ,C� ,-r• n <br /> 12 <br /> 5 tldtl } <br /> 1% Brealhing rate increases slightly. <br /> 2% Breathing rate increases to 50%above normal level. Prolonged exposure can <br /> cause headache,tiredness, _ <br /> 3% Breathing Increases to twice normal rete and becomes labored. Weak narcotic <br /> effect. Impaired hearing,headache, increased blood pressure and pulse rate- <br /> 4-5% Breathing Increases to approximately four times normal rate,symptoms of <br /> Intoxication become evident,and slight choking may be fell. <br /> 5-10% Characteristic sharp oder noticeable. Very labored breathing,visual Impairment, <br /> headache,and ringing In the ears. Judgment may be impaired,followed within <br /> minutas by toss of consciousness. <br /> 10-100% Unconsciousness occurs more repldty above 10%level. prolonged exposuro to <br /> high concentrations may eventually result In death from asphyxiation, <br /> The welding process may generate hazardous fumesigases, (See sections 10 and 16,) <br /> Skin Contact. No harm expected from vapor. Cold gas, or liquid or solid carbon dioxide may <br /> cause severe frostblte. <br /> �J J Page 6 of 12 <br />
