**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Appearance: dark red-brown.
Caution! May cause respiratory tract irritation.
May cause skin
irritation. May cause eye irritation. May cause
allergic skin
reaction. This substance has caused adverse
reproductive and fetal
effects in animals.
Target Organs: None.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Low hazard for usual industrial handling.
Inhalation:
May cause respiratory tract irritation. Low hazard for usual
industrial handling.
Chronic:
May cause reproductive and fetal effects.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
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. Wash clothing before reuse. Flush skin with plenty
of
soap and water. Destroy contaminated shoes.
Ingestion:
If
victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid.
Notes to Physician:
Treat symptomatically and
**** 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. This
material in sufficient quantity and reduced particle size is capable
of
creating a dust explosion. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Autoignition Temperature:Not
applicable.
Flash Point:
Not applicable.
Explosion Limits, lower:Not
available.
Explosion Limits, upper:Not
available.
NFPA Rating: (estimated) Health:
2; Flammability: 1; Reactivity: 0
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use
proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. May form flammable
dust-air mixtures. Keep container tightly closed. Do not get on skin
or
in eyes. Wash clothing before reuse.
Storage:
Keep away from heat and flame. Store in a cool, dry place. Keep
containers tightly closed.
**** 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.
