Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: white.
Warning! Flammable solid. May cause allergic respiratory and skin reaction. May cause eye, skin, and respiratory tract irritation.
Target Organs: Respiratory system, skin.


Potential Health Effects
Eye: May cause mild eye irritation.
Skin: May cause mild 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.
Inhalation: May cause allergic respiratory reaction. Inhalation of dust may cause respiratory tract irritation.
Chronic: Repeated exposure may cause allergic respiratory reaction (asthma).

Section 4 - First Aid Measures


Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid.
Skin: In case of contact, immediately flush skin with soap and plenty of water. Remove contaminated clothing and shoes. Get medical aid if symptoms occur. Wash clothing before reuse.
Ingestion: 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: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: 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. Containers may explode in the heat of a fire. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid. May re-ignite after fire is extinguished. May be ignited by friction, heat, sparks, or flame.
Extinguishing Media: Use water fog, dry chemical, carbon dioxide, or regular foam. Cool containers with flooding quantities of water until well after fire is out.
Flash Point: 250 deg C ( 482.00 deg F)
Autoignition Temperature: 390 deg C ( 734.00 deg F)
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating: (estimated) Health: 2; Flammability: 2; Instability: 2

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, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Use a spark-proof tool.

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. Avoid ingestion and inhalation. Use with adequate ventilation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage: Keep away from heat, sparks, and flame. Store in a cool, dry place. Keep container closed when not in use. Keep away from strong acids.

Section 8 - Exposure Controls, Personal Protection


Engineering Controls: Ventilation fans and other electrical service must be non-sparking and have an explosion-proof design. Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels.
