POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Not normally a hazard due to physical form of product.  

EYE

  Not considered to be a risk because of the extreme volatility of the gas.  

SKIN

  Not normally a hazard due to physical form of product.  

INHALED

  Inhalation of non-toxic gases may cause:  ·  CNS effects: headache, confusion, dizziness, stupor, seizures and coma;  ·  respiratory: shortness of breath and rapid breathing;  ·  cardiovascular: collapse and irregular heart beats;  ·  gastrointestinal: mucous membrane irritation, nausea and vomiting.  Symptoms of asphyxia (suffocation) may include headache, dizziness, shortness of breath, muscular weakness, drowsiness and ringing in the ears. If the asphyxia is allowed to progress, there may be nausea and vomiting, further physical weakness and unconsciousness and, finally, convulsions, coma and death. Significant concentrations of the non-toxic gas reduce the oxygen level in the air. As the amount of oxygen is reduced from 21 to 14 volume %, the pulse rate accelerates and the rate and volume of breathing increase. The ability to maintain attention and think clearly is diminished and muscular coordination is somewhat disturbed. As oxygen decreases from 14-10% judgement becomes faulty; severe injuries may cause no pain. Muscular exertion leads to rapid fatigue. Further reduction to 6% may produce nausea and vomiting and the ability to move may be lost. Permanent brain damage may result even after resuscitation at exposures to this lower oxygen level. Below 6% breathing is in gasps and convulsions may occur. Inhalation of a mixture containing no oxygen may result in unconsciousness from the first breath and death will follow in a few minutes.  

CHRONIC HEALTH EFFECTS

  Principal route of occupational exposure to the gas is by inhalation.
