Dust may cause mechanical irritation.
Skin:
Dust may cause mechanical irritation. Low hazard for usual industrial handling.
Ingestion:
No hazard expected in normal industrial use.
Inhalation:
Inhalation of dust may cause respiratory tract irritation.
Chronic:
No information found.

---

Section 4 - FIRST AID MEASURES
? Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation develops, get medical aid.
Skin:
Get medical aid if irritation develops or persists. No specific treatment is necessary, since this material is not likely to be hazardous.

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. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

---

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. Forms smooth, slippery surfaces on floors, posing an accident risk. 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. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid breathing dust.
Storage:
Store in a cool, dry place. Store in a tightly closed container.

---

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
? Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits CAS# 11138-66-2: 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:
Glove protection is not normally required.
Clothing:
Protective garments not normally required.
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.
