Eye contact: Immediately flush eyes with copious amounts of water or eyewash solution for at least 15
minutes; lift eyelids occasionally. If irritation persists, consult physician.
Skin contact: Immediately remove contaminated clothing and shoes, then wash skin with soap and copious
amounts of water. If irritation persists, consult physician.

Flash Point: NA Method: NA Autoignition: NE
OSHA Flammability Class: NA Explosion Limits: upper: NE
NFPA: See Section 3 Hazards Identification Emergency Overview above. lower: NE
Extinguishing Media
Water spray, carbon dioxide, dry chemical powder, or appropriate foam.
Special or Standard Fire Fighting Procedures
Standard precautions for fighting large fires involving chemicals: Wear self-contained breathing apparatus
(SCBA) and protective clothing to prevent contact with skin and eyes.
Standard Fire and Explosion Hazards
Slight fire hazard--As with most organic compounds, fire is possible at elevated temperatures or from contact
with an ignition source.
Explosion potential unknown--If a substance is an organic solid, fine dust dispersed in air in sufficient
concentrations in the presence of an ignition source is a potential for a dust explosion.
Avoid inhalation of material or combustion by-products.
Unusual Fire and Explosion Hazards
None
Hazardous Combustion or Decomposition Products
May emit carbon monoxide, carbon dioxide, sulfur oxides
SECTION 6......................................................... ACCIDENTAL RELEASE MEASURES..................................................................................
Eliminate all ignition sources/slight fire hazard.
Evacuate unnecessary people from area. Isolate spilled material.
Ventilate area.
Wear protective clothing to prevent contact with skin and eyes (lab coat, gloves, safety glasses).
Wear NIOSH/MSHA approved respirator for dust to prevent potential inhalation irritation.
If in solution, mix with sand or similar adsorbent material.
Sweep up, seal in appropriate hazardous waste container, and hold for proper waste disposal.
Avoid raising dust as it is a powdered material.
Wash spill site after material pickup is complete.
Standard chemical precautions: Keep out of water supplies and sewers.
