EMERGENCY OVERVIEW
The toxicological properties of this material have not been fully
investigated.
Potential Health Effects
Eye:
May cause eye irritation. Causes redness and pain.
Skin:
May cause skin irritation. Causes redness and pain.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause cardiac disturbances. May cause disturbed blood
electrolyte balance.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Prolonged or repeated exposure may cause adverse reproductive
effects. Prolonged or repeated exposure may cause permanent eye
damage. Laboratory experiments have resulted in mutagenic effects.
**** 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.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid if cough or other symptoms appear.
Notes to Physician:
Weak acids such as acetic acid and propionic acid can be used as
chemical antidotes, demulcents and stimulants. Treat symptomatically
and supportively.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid breathing dust,
vapor, mist, or gas. Avoid contact with eyes, skin, and clothing.
Keep container tightly closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits

Russia: 10 mg/m3 TWA
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure. Wear impervious gloves.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
