  • INHALATION
    		• Blue lips or finger nails. Blue skin. Headache. Dizziness. Nausea. Confusion. Laboured breathing. Convulsions. Unconsciousness.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! (Further see Inhalation).
    		Protective gloves. Protective clothing.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
  • EYES

    		• Face shield.
