First-aid measures

4.1 Description of first aid measuresGeneral advice: First Aid responders should pay attention to self-protection and use the recommended protective clothing (chemical resistant gloves, splash protection). Inhalation: Move person to fresh air. If not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc). If breathing is difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a medical facility. Skin Contact: Wash skin with plenty of water. Eye Contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the initial 1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a physician, preferably an ophthalmologist. Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical personnel. 4.2 Most important symptoms and effects, both acute and delayedAside from the information found under Description of first aid measures (above) and Indication of immediate medical attention and special treatment needed (below), no additional symptoms and effects are anticipated.4.3 Indication of immediate medical attention and special treatment neededMaintain adequate ventilation and oxygenation of the patient. Administer 100% oxygen to relieve headache and a general sense of weakness. Determine methemoglobin concentration of blood every 3 to 6 hours for first 24 hours. It should return to normal within 24 hours. The treatment of toxic methemoglobinemia may include the intravenous administration of methylene blue. If methemoglobin >10-20% consider methylene blue 1-2 mg/kg body weight as 1% solution intravenously over 5 minutes followed by 15-30 cc flush (Price D, Methemoglobinemia, Goldfrank Toxicologic Emergencies, 5th ed., 1994). Also provide 100% oxygen. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient. Methemoglobinemia may aggravate any preexisting condition sensitive to a decrease in available oxygen, such as chronic lung disease, coronary artery disease or anemia.

Fire-fighting measures

5.1 Extinguishing MediaWater fog or fine spray. Dry chemical fire extinguishers rated tri-class ABC (containing monoammonium phosphate). Carbon dioxide fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective. Extinguishing Media to Avoid: Do not use bicarbonate based dry chemical extinguishers (Class BC). Do not use direct water stream. Straight or direct water streams may not be effective to extinguish fire. 5.2 Special hazards arising from the substance or mixtureHazardous Combustion Products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating. Combustion products may include and are not limited to: Nitrogen oxides. Carbon monoxide. Carbon dioxide. Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. Contamination with sensitizing compounds (amines, alkalies, acids, heavy metal salts) can cause formation of shock sensitive or highly reactive materials. Violent steam generation or eruption may occur upon application of direct water stream to hot liquids. Vapors are heavier than air and may travel a long distance and accumulate in low lying areas. Ignition and/or flash back may occur. Flammable mixtures may exist within the vapor space of containers at room temperature. Flammable concentrations of vapor can accumulate at temperatures above flash point.5.3 Advice for firefightersFire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Stay upwind. Keep out of low areas where gases (fumes) can accumulate. Water may not be effective in extinguishing fire. Do not use direct water stream. May spread fire. Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container. Hand held ABC type dry chemical, carbon dioxide or water extinguishers may be used for small fires. Do not use bicarbonate based dry chemical extinguishers (Class BC). Reaction with alkaline bicarbonates or other strong alkalis can form salts that may reignite when dry. If bicarbonate extinguishers are used and salts are formed, keep residues wet with water and dispose of in accordance with local regulations. Eliminate ignition sources. Move container from fire area if this is possible without hazard. Burning liquids may be moved by flushing with water to protect personnel and minimize property damage. Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, boots, and gloves). If protective equipment is not available or not used, fight fire from a protected location or safe distance.

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures: Isolate area. Keep unnecessary and unprotected personnel from entering the area. Keep personnel out of low areas. Keep upwind of spill. Ventilate area of leak or spill. No smoking in area. For large spills, warn public of downwind explosion hazard. Use appropriate safety equipment.6.2 Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. 6.3 Methods and materials for containment and cleaning up: Contain spilled material if possible. Vapor explosion hazard. Keep out of sewers. Use non-sparking tools in cleanup operations. Eliminate all sources of ignition in vicinity of spill or released vapor to avoid fire or explosion. Pump with explosion-proof equipment. If available, use foam to smother or suppress. Pump into suitable and properly labeled containers.

Handling and storage

7.1 Precautions for safe handlingHandling General Handling: Keep away from heat, sparks and flame. Avoid contact with strong alkalis, amines or acids. Avoid contact with eyes. Avoid breathing vapor. Do not swallow. Wash thoroughly after handling. Keep container closed. Use only with adequate ventilation. No smoking, open flames or sources of ignition in handling and storage area. Vapors are heavier than air and may travel a long distance and accumulate in low lying areas. Ignition and/or flash back may occur. Never use air pressure for transferring product. Electrically bond and ground all containers and equipment before transfer or use of material. Containers, even those that have been emptied, can contain vapors. Do not cut, drill, grind, weld, or perform similar operations on or near empty containers. Use of non-sparking or explosion-proof equipment may be necessary, depending upon the type of operation.Other Precautions: Do not use positive displacement pumps with this material. 7.2 Conditions for safe storage, including any incompatibilitiesStorage Minimize sources of ignition, such as static build-up, heat, spark or flame. Keep container closed. Do not store in: Brass. Copper. Copper alloys. Lead and its alloys. Corrosive when wet (greater than 0.2 weight percent). Store in stainless steel or aluminum if wet. 7.3 Specific end usesSee the technical data sheet on this product for further information.
