EMERGENCY OVERVIEW
Appearance: orange liquid.
Danger! Toxic if inhaled. Danger of serious damage
to health by prolonged exposure through inhalation. Strong oxidizer.
Contact with other material may cause a fire. May cause harm to the
unborn child. May impair fertility. Harmful if swallowed. May cause
allergic respiratory and skin reaction. Toxic to aquatic organisms,
may cause long-term adverse effects in the aquatic environment.
Cancer hazard. May cause cancer in humans. May cause heritable
genetic damage.
Target Organs: Blood, kidneys, central nervous
system, liver, respiratory system, skin.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
May be harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
May cause nausea and vomiting.
Inhalation:
May cause allergic respiratory reaction. May cause respiratory tract
irritation. Toxic if inhaled.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
liver and kidney damage. May cause cancer in humans. 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. Exposure to high
concentrations may cause central nervous system depression.

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.

|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Wear a self contained breathing
apparatus and appropriate personal protection. (See Exposure
Controls, Personal Protection section). Do not use combustible
materials such as paper towels to clean up spill. Keep combustibles
(wood, paper, oil, etc.,) away from spilled material. Do not let
this chemical enter the environment.
|
Section 7 - Handling and Storage
|
Handling:
Use spark-proof tools and explosion proof equipment. Do not get in

combustible materials.
Storage:
Do not store near combustible materials. Store in a cool, dry place.
Store in a tightly closed container.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use only under a chemical fume hood.
