  • TLV-TWA (Time Weighted Average): 0.2 mg/m³, as benzene soluble aerosol [1984][4]
  • IDLH: NIOSH considers coal tar pitch volatiles to be potential occupational carcinogens. (coal tar pitch volatiles)[5]

First aid

  • 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. Skin: Immediately flood affected skin with water while removing and isolating all contaminated clothing.[1]
  • Fresh air, rest. Refer for medical attention.[3]
  • Remove contaminated clothes. Rinse and then wash skin with water and soap.[3]
  • First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.[3]

Storage

  • Separated from strong oxidants. Well closed.[3]
  • Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Non Combustible Solids.[5]
  • Store in a secure poison location. ... Before entering a confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Anthracene must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine), chromic acid, and calcium hypochlorite, since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area.[5]

Incompatibilities

  • Incompatible materials: Strong oxidizing agents, hypochlorites.[5]
  • Anthracene will burst into flame on contact with chromic acid.[5]
  • Anthracene heats on contact with calcium hypochlorite.[5]
  • Explodes on contact with fluorine.[5]
