Section 4 - First Aid Measures
ORAL EXPOSURE
If swallowed, wash out mouth with water provided person is
conscious. Call a physician. Do not induce vomiting.
INHALATION EXPOSURE
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
DERMAL EXPOSURE
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
EYE EXPOSURE
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.

EXTINGUISHING MEDIA
Suitable: Noncombustible. Use extinguishing media appropriate to
surrounding fire conditions.
Unsuitable: Do not use water.
FIREFIGHTING
Protective Equipment: Wear self-contained breathing apparatus
and protective clothing to prevent contact with skin and eyes.
Specific Hazard(s): Emits toxic fumes under fire conditions.
Contact with other material may cause fire.
Section 6 - Accidental Release Measures
PROCEDURE TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Cover with dry lime or soda ash, pick up, keep in a closed
container, and hold for waste disposal. Ventilate area and wash
spill site after material pickup is complete.
Section 7 - Handling and Storage
HANDLING
User Exposure: Do not breathe vapor. Do not get in eyes, on
skin, on clothing. Avoid prolonged or repeated exposure.
STORAGE
SIAL - 435589 www.wpiinc.com Page 2
Suitable: Keep tightly closed.
Incompatible Materials: Do not allow contact with water
Section 8 - Exposure Controls / PPE
ENGINEERING CONTROLS
Safety shower and eye bath. Use only in a chemical fume hood.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory: Use respirators and components tested and approved
under appropriate government standards such as NIOSH (US) or CEN
(EU). Where risk assessment shows air-purifying respirators are
appropriate use a full-face respirator with multi-purpose
combination (US) or type ABEK - P3 (EN 14387) respirator
cartridges as a backup to engineering controls. If the respirator
is the sole means of protection, use a full-face supplied air
respirator.
Hand: Compatible chemical-resistant gloves.
Eye: Chemical safety goggles.
Other: Faceshield (8-inch minimum).
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Discard contaminated
shoes. Wash thoroughly after handling.

Section 11 - Toxicological Information
ROUTE OF EXPOSURE
Skin Contact: Causes severe burns.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes severe burns.
Inhalation: May be harmful if inhaled. Material is extremely
destructive to the tissue of the mucous membranes and upper
respiratory tract.
Ingestion: Ingestion can cause immediate burning pain in the
mouth, throat, abdomen; severe swelling of the larynx and
skeletal paralysis affecting the ability to breathe, circulatory
shock and convulsions. May be harmful if swallowed.
SIGNS AND SYMPTOMS OF EXPOSURE
To the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Inhalation may result in spasm, inflammation and edema
of the larynxand bronchi, chemical pneumonitis, and pulmonary
edema. Material is extremely destructive to tissue of the mucous
