4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of contact, immediately wash skin with soap and copious
amounts of water.
AFTER EYE CONTACT
In case of contact, immediately flush eyes with copious amounts
of water for at least 15 minutes.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
5 - Fire Fighting Measures
EXTINGUISHING MEDIA
Suitable: For small (incipient) fires, use media such as
ALDRICHwww.molbase.com
"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.
SPECIAL RISKS
Specific Hazard(s): Combustible liquid. Emits toxic fumes under
fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
6 - Accidental Release Measures
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear respirator, chemical safety goggles, rubber boots, and
heavy rubber gloves.
METHODS FOR CLEANING UP
Absorb on sand or vermiculite and place in closed containers for
disposal. Ventilate area and wash spill site after material
pickup is complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Avoid inhalation. Avoid contact
with eyes, skin, and clothing. Avoid prolonged or repeated
exposure.
STORAGE
Conditions of Storage: Keep tightly closed. Keep away from heat
and open flame. Store in a cool dry place.
8 - Exposure Controls / Personal Protection
ENGINEERING CONTROLS
Safety shower and eye bath. Mechanical exhaust required.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling. Wash contaminated clothing before
reuse.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US)
or CEN (EU). Respiratory protection is not required. Where
protection is desired, use multi-purpose combination (US) or type
ABEK (EN 14387) respirator cartridges.
Hand Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.
