**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Risk of explosion if heated under
confinement.Light sensitive.
Potential Health Effects
Eye:
Dust may cause mechanical irritation. May cause lacrimation
(tearing), blurred vision, and photophobia. May cause chemical
conjunctivitis and corneal damage.
Skin:
May cause skin irritation and possible burns.
Ingestion:
May cause irritation of the digestive tract. May cause nausea,
vomiting, abdominal pain, and increased salivation.
Inhalation:
Inhalation of dust may cause respiratory tract irritation. Olfactory
fatigue may occur. Can produce delayed pulmonary edema.
Chronic:
No information found.
**** 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
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:
**** 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. Dust can be
an explosion hazard when exposed to heat or flame. Flammable solid.
May burn rapidly with flare burning effect. May re-ignite after fire
is extinguished. Containers may explode when heated. Risk of
explosion if heated under confinement.
Extinguishing Media:
Use water spray to cool fire-exposed containers. For large fires,
use water spray, fog or regular foam. Contact professional
fire-fighters immediately. For small fires, use dry chemical, carbon
dioxide, sand, earth, water spray or regular foam. Cool containers
with flooding quantities of water until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Scoop up with a nonsparking tool,
then place into a suitable container for disposal. Avoid generating
dusty conditions. Remove all sources of ignition. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Keep away from heat, sparks
and flame. Avoid ingestion and inhalation. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames.
Storage:
Keep away from sources of ignition. 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 2592-95-2:
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.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
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.

decomposition. Heating may cause an explosion.
Conditions to Avoid:
Incompatible materials, ignition sources, dust generation, excess
heat, strong oxidants, heating above the melting point (155-158C).
Incompatibilities with Other Materials:
Strong oxidizing agents, copper nitrate.
Hazardous Decomposition Products:
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and
gases, carbon dioxide, nitrogen.
Hazardous Polymerization: Has not been reported.
