EMERGENCY OVERVIEW
Appearance: colorless to light brown liquid.
Danger! Toxic if inhaled. Reacts violently with
water. Causes burns by all exposure routes. Causes respiratory tract
irritation. Cancer hazard. May cause liver damage. Hygroscopic
(absorbs moisture from the air).
Target Organs: Liver, respiratory system,
gastrointestinal system, eyes, skin.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May be harmful if absorbed through the skin.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Causes chemical burns to the respiratory tract. Toxic if inhaled.
Inhalation may cause severe irritation to the respiratory tract with
sore throat, coughing, labored breathing, and possible pulmonary
edema.
Chronic:
May cause cancer in humans. Chronic exposure may cause liver damage.
|
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Do not induce vomiting. Get medical aid immediately. Call a poison
control center.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. SPEED IS ESSENTIAL, OBTAIN MEDICAL AID
IMMEDIATELY. Do not use mouth-to-mouth resuscitation if victim
ingested or inhaled the substance; induce artificial respiration
with the aid of a pocket mask equipped with a one-way valve or other
proper respiratory medical device.
Notes to Physician:
Treat symptomatically and supportively.
