Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
If Tyvek-type disposable protective clothing is not worn during handling of this chemical, wear disposable Tyvek-type sleeves taped to your gloves.
Respirators
Wear a NIOSH-approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter).
Small spills/leaks
If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Stability
No data.
Incompatibilities
Can react with strong oxidizing agents May react with electrophiles, peroxides, nitrogen oxides and sulfur oxides

Fire.
Fire fighting
Fires involving this chemical can be controlled with a dry chemical, carbon dioxide or Halon extinguisher.
Fire potential
This material is probably combustible.
Combustion products
Fire may produce irritating and/or toxic gases.

Health.
Exposure limit(s)
OSHA: PEL (8 h TWA): 0.2 mg/m3.
Carcinogin
G-A2, I-2B, N-2, CP65
Exposure effects
In experimental animal studies, PAHs and metabolites cross the placenta. Female offspring of experimental animals exposed to PAHs during pregnancy have a decrease in the number of functional oocytes, sometimes such that they are infertile. <br>PAHs are lipophilic and are excreted in breast milk, allowing for secondary exposure of nursing infants, although the potential significance of such exposure has not been determined.
   Ingestion
Leukoplakia and cancers of the lip and oral cavity can develop with chronic exposure.
   Inhalation
Irritation, chronic cough, bronchitis, and bronchogenic cancer can occur with chronic exposure.
   Skin
Coal tar warts (precancerous lesions enhanced by uv light exposure), erythema, dermal burns, acneiform lesions, photosensitization and cancer may develop following chronic exposure.
   Eyes
See Skin.

First aid
 
   Ingestion
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital.
   Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
   Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.
   Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
