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.
Section 5 - Fire Fighting Measures
FLAMMABLE HAZARDS
Flammable Hazards: Yes
EXPLOSION HAZARDS
Vapor may travel considerable distance to source of ignition and
flash back. Container explosion can occur under fire conditions.
In advanced or massive fires the area should be evacuated and
the fire should be fought from a remote explosion-resistant
location. Forms explosive mixtures in air.

EXTINGUISHING MEDIA
Suitable: For small (incipient) fires, use media such as
"alcohol" foam, dry chemical, or carbon dioxide. For large
fires, apply water from as far as possible. Use very large
quantities (flooding) of water applied as a mist or spray; solid
streams of water may be ineffective. Cool all affected
containers with flooding quantities of water.
FIREFIGHTING
Protective Equipment: Wear self-contained breathing apparatus
and protective clothing to prevent contact with skin and eyes.
Specific Hazard(s): Flammable liquid. Emits toxic fumes under
fire conditions.
Specific Method(s) of Fire Fighting: Use water spray to cool
fire-exposed containers.
Section 6 - Accidental Release Measures
PROCEDURE TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area. Shut off all sources of ignition.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Cover with an activated carbon adsorbent, take up and place in
closed containers. Transport outdoors. Ventilate area and wash
spill site after material pickup is complete.
Section 7 - Handling and Storage
ALDRICH - 344508 www.sigma-aldrich.com Page 2
HANDLING
User Exposure: Do not breathe vapor. Avoid contact with eyes,
skin, and clothing. Avoid prolonged or repeated exposure.
STORAGE
Suitable: Keep container closed. Keep away from heat, sparks,
and open flame.
Store at 2-8掳C
Section 8 - Exposure Controls / PPE
ENGINEERING CONTROLS
Safety shower and eye bath. Use nonsparking tools. Mechanical
exhaust required.
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 AXBEK (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.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling. Wash contaminated clothing before
reuse.
