benzil
C_14H10O2    fw=210.24

Hazards

Avoid contact.

Causes skin and eye irritation upon contact. May also cause chemical conjunctivitis.

If ingested, may cause irritation of the digestive tract with nausea, vomiting and diarrhea. If inhaled, may cause respiratory tract irritation. Can produce delayed pulmonary edma. (23)

Emergency Procedures

If benzil makes contact with your eyes, flush eyes with plenty of water for at least 15 minutes, occationally lifting the upper and lower eyelids.

If contact with skin occurs, remove any contaminated clothing or shoes and wash contaminated area of skin for at least 15 minutes with soap and water.
