Naphtha (petroleum), steam-cracked, C8-11 aromatic hydrocarbon and cycloalkadiene fraction

Guidance on Safe Use

First-aid measures

Eye Contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, preferably from an ophthalmologist.  

Skin Contact: Wash skin with plenty of water.  

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.  

Ingestion: Seek medical attention immediately.  Do not induce vomiting. Call a physician and/or transport to emergency facility immediately.  

Notes to Physician: Maintain adequate ventilation and oxygenation of the patient.  May cause asthma-like (reactive airways) symptoms.  Bronchodilators, expectorants, antitussives and corticosteroids may be of help.  Exposure may increase "myocardial irritability". Do not administer sympathomimetic drugs such as epinephrine unless absolutely necessary.  Due to irritant properties, swallowing may result in burns/ulceration of mouth, stomach and lower gastrointestinal tract with subsequent stricture. Aspiration of vomitus may cause lung injury. Suggest endotracheal/esophageal control if lavage is done.  The decision of whether to induce vomiting or not should be made by a physician.  If burn is present, treat as any thermal burn, after decontamination.  Alcohol consumed before or after exposure may increase adverse effects.  No specific antidote.  Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.  

Medical Conditions Aggravated by Exposure: Skin contact may aggravate preexisting dermatitis.

Fire-fighting measures

Extinguishing Media: Water fog or fine spray.  Dry chemical fire extinguishers.  Carbon dioxide fire extinguishers.  Foam.  Do not use direct water stream.  Straight or direct water streams may not be effective to extinguish fire.  Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective.  

Fire 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.  Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed.  Do not use direct water stream.  May spread fire.  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.  Avoid accumulation of water.  Product may be carried across water surface spreading fire or contacting an ignition source.  Contain fire water run-off if possible. Fire water run-off, if not contained, may cause environmental 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).  Avoid contact with this material during fire fighting operations. If contact is likely, change to full chemical resistant fire fighting clothing with self-contained breathing apparatus.  If this is not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire from a remote location.  For protective equipment in post-fire or non-fire clean-up situations, refer to the relevant sections.  

Unusual Fire and Explosion Hazards: 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.  Dense smoke is produced when product burns.  

Hazardous 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:  Carbon monoxide.  Carbon dioxide.  Aromatic hydrocarbons.

Accidental release measures

Steps to be Taken if Material is Released or Spilled: Small spills:  Contain spilled material if possible.  Collect in suitable and properly labeled containers.  Large spills:  Dike area to contain spill.  Wash the spill site with large quantities of water.  Collect with vacuum equipment.  Pump with explosion-proof equipment.  If available, use foam to smother or suppress.  

Personal Precautions: Evacuate area.  Ventilate area of leak or spill.  Use appropriate safety equipment. Eliminate all sources of ignition in vicinity of spill or released vapor to avoid fire or explosion.  Ground and bond all containers and handling equipment.  If available, use foam to suppress vapors.  For large spills, warn public of downwind explosion hazard.  Vapor explosion hazard.  Keep out of sewers.  Check area with combustible gas detector before reentering area. Ground and bond all containers and handling equipment.  Eliminate all sources of ignition in vicinity of spill or released vapor to avoid fire or explosion.  

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater.

Handling and storage

General Handling: Do not swallow.  Avoid contact with eyes, skin, and clothing.  Use with adequate ventilation.  Avoid breathing vapor.  Electrically bond and ground all containers, personnel and equipment before transfer or use of material.  Use of non-sparking or explosion-proof equipment may be necessary, depending upon the type of operation.  Keep container closed.  No smoking, open flames or sources of ignition in handling and storage area.  This product is a poor conductor of electricity and can become electrostatically charged, even in bonded or grounded equipment.  If sufficient charge is accumulated, ignition of flammable mixtures can occur.  Handling operations that can promote accumulation of static charges include but are not limited to mixing, filtering, pumping at high flow rates, splash filling, creating mists or sprays, tank and container filling, tank cleaning, sampling, gauging, switch loading, vacuum truck operations.  

Other Precautions: Never use air pressure for transferring product.  Vapors are heavier than air and may travel a long distance and accumulate in low lying areas. Ignition and/or flash back may occur.  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.  Spills of these organic materials on hot fibrous insulations may lead to lowering of the autoignition temperatures possibly resulting in spontaneous combustion.  

Storage

Minimize sources of ignition, such as static build-up, heat, spark or flame.
