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

Contact local poison control center or physician immediately. Never make an unconscious person vomit or drink fluids. If vomiting occurs, keep head lower than hips to help prevent aspiration. If person is unconscious, turn head to side. Get medical attention immediately. For ingestion, consider gastric lavage and catharsis. 

For inhalation, consider oxygen. For skin contact, consider ice water bath. 

See Section 9 for Flammability Properties 

Moderate fire hazard. Severe explosion hazard. Dust/air mixtures may ignite or explode. Electrostatic discharges may be generated by flow or agitation resulting in ignition or explosion. Flood with water. If no water is available, use dry chemical or earth. 

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. Flood with water. Explosive. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Evacuate if fire gets out of control or containers are directly exposed to fire. Evacuation radius: 500 feet. 

Dig holding area such as lagoon, pond or pit for containment. Cover with plastic sheet or tarp to minimize spreading and protect from contact with water. Dig holding area such as lagoon, pond or pit for containment. Cover with plastic sheet or tarp to minimize spreading and protect from contact with water. 

Trap spilled material at bottom in deep water pockets, excavated holding areas or within sand bag barriers. Absorb with activated carbon. Remove trapped material with suction hoses. Collect spilled material using mechanical equipment. Trap spilled material at bottom in deep water pockets, excavated holding areas or within sand bag barriers. Absorb with activated carbon. Remove trapped material with suction hoses. Collect spilled material using mechanical equipment. 

Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Small spills: Flood with water. 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. Notify Local Emergency Planning Committee and State Emergency Response Commission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs in the U.S. and is reportable under CERCLA Section 103, notify the National Response Center at (800)424-8802 (USA) or (202)426-2675 (USA). 

Store and handle in accordance with all current regulations and standards. Store in a tightly closed container. Store in a cool, dry place. Store in a well-ventilated area. Store in a cool, dry place. Keep in the dark. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 

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

Eyes/Face Wear splash resistant safety goggles with a faceshield. 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 supplied-air respirator with a full facepiece that is operated in a 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. 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.
