If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. Get immediate medical attention. 

Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention, if needed. Thoroughly clean and dry contaminated clothing and shoes before reuse. 

Flush eyes with plenty of water for at least 15 minutes. Then get immediate medical attention.

See Section 9 for Flammability Properties 

Moderate fire hazard. Dust/air mixtures may ignite or explode. May explode if exposed to shock, friction or heating. 

regular dry chemical, dry sand, earth, regular foam, water Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Use extinguishing agents appropriate for surrounding fire. Avoid inhalation of material or combustion by-products. Water may be ineffective. 

oxides of carbon, oxides of nitrogen, hydrogen cyanide 

Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Small spills: Collect spilled material in appropriate container for disposal. Move containers away from spill to a safe area. Large spills: Wet down area with water. Dike for later disposal. Remove sources of ignition. Keep unnecessary people away, isolate hazard area and deny entry. 

Use methods to minimize dust. 

Store and handle in accordance with all current regulations and standards. Store between 0 C and 8 C. Store in a tightly closed container. Store in a cool, dry place. Avoid contact with temperatures above 50 C. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 

Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Provide local exhaust ventilation system. Ensure compliance with applicable exposure limits. 

Eyes/Face Wear splash resistant safety goggles. Provide an emergency eye wash fountain and quick drench shower in the immediate work area. 

Wear appropriate chemical resistant clothing. 

Wear appropriate chemical resistant gloves. 

Under conditions of frequent use or heavy exposure, respiratory protection may be needed. Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before use. Any air-purifying half-mask respirator equipped with organic vapor cartridge(s) in combination with an N95, R95, or P95 filter. The following filters may also be used: N99, R99, P99, N100, R100 or P100. Any air-purifying full-facepiece respirator (gas mask) with a chin-style, front-mounted or back-mounted organic vapor canister having an N100, R100, or P100 filter. Any powered, air-purifying respirator with a tight-fitting facepiece, organic vapor cartridge(s) and high-efficiency particulate filter(s). Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode. For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode.
