Section 3 - Hazards Identification
Appearance: clear yellow liquid.
Danger! Toxic if absorbed through the skin. May be
fatal if inhaled. Causes burns by all exposure routes. Harmful if
swallowed. Lachrymator (substance which increases the flow of tears).
Toxic to aquatic organisms, may cause long-term adverse effects in
the aquatic environment. May cause allergic skin reaction. May cause
central nervous system effects. May cause liver and kidney damage.
Target Organs: Blood, kidneys, central nervous
system, liver, spleen, respiratory system, gastrointestinal system,
Potential Health Effects
Causes eye burns. Lachrymator (substance which increases the flow
Causes skin burns. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Toxic in contact with skin.
Harmful if swallowed. Causes gastrointestinal tract burns. May cause
liver and kidney damage.
May be fatal if inhaled. Causes chemical burns to the respiratory
tract. May cause central nervous system effects.
Repeated exposure may cause damage to the spleen. Adverse
reproductive effects have been reported in animals. Laboratory
experiments have resulted in mutagenic effects. Chronic exposure may
cause blood effects. Repeated or prolonged exposure may cause
allergic reactions in sensitive individuals.
Section 4 - First Aid Measures
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
Do not induce vomiting. Get medical aid immediately. Call a poison
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.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Substance may react with water, and may release
corrosive and/or toxic gases.
Do NOT use water directly on fire. Use foam, dry chemical, or carbon
