EMERGENCY OVERVIEW
Appearance: slightly yellow crystalline powder.
Warning! Eye contact may result in permanent eye
damage. Causes eye and respiratory tract irritation. Contact with
acids liberates toxic gas.
Target Organs: Respiratory system, eyes.
Potential Health Effects
Eye:
Causes redness and pain. Causes severe burning pain and redness of
the conjunctiva. Risk of serious damage to eyes.
Skin:
May cause skin irritation. May be harmful if absorbed through the
skin. May cause reddening of the skin.
Ingestion:
May cause irritation of the digestive tract. May be harmful if
swallowed.
May cause worsening of asthma in asthmatics. Individuals sensitive to
sulfides may experience stomach upset, tightness in the chest, or
Inhalation:
Causes respiratory tract irritation. May be harmful if inhaled. May
cause respiratory difficulty and coughing.
Chronic:
Repeated or prolonged exposure may cause allergic reactions in
sensitive individuals.
|
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
