Gefahrenübersicht	A strong skin, eye, and mucous membrane irritant[HSDB] May burn skin and eyes[CAMEO] See Arsenic and linked occupational diseases.The major hazards encountered in the use and handling of phenyldichloroarsine stem from its toxicologic properties. Toxic by all routes (ie, inhalation, ingestion, and dermal contact), exposure to this liquid material may occur from its manufacture or use as a lacrymator, and solvent for diphenylcyanoarsine. Effects from exposure may include contact burns to the skin and eyes, he adache, generalized weakness, nausea, hemoglobinuria, and death (if sufficient quantities are inhaled). OSHA has established a time-weighted average (TWA) limit of 0.5 mg/cu m for organic arsenic compounds. Mechanical ventilation should be used to maintain phenyldichloroarsine at, or below the OSHA limits. In activities and situations where over-exposure may occur, wear a positive pressure, self-contained breathing apparatus and chemical protective clothing which is specifically recommended by the shipper or manufacturer. If exposure should occur, immediately flush exposed eyes and skin with running water for at least 15 minutes. Remove contaminated clothing at the site. While phenyldichloroarsine does not ignite easily, it can burn with the production of poisonous gases. Also, containers of this substance may explode violently in the heat of a fire. For fires involving phenyldichloroarsine, extinguish with dry chemical, CO2, water spray, fog, or standard foam. Dike fire control water and do not scatter the material. Phenyldichloroarsine may be shipped domestically via air, rail, road, and water, in containers bearing the label, "Poison." For small spills of this substance, take up with sand or other noncombustible absorbent and place into containers for later disposal. Dike far ahead of large spills for later disposal.
