• 一般的な説明

  A colorless crystalline solid, or a dark-brown liquid. Strongly irritating to skin and eyes. Toxic by ingestion and inhalation. Used as a military poison gas.

• 空気と水の反応

  Slowly decomposed by water [Hawley].

• 反応プロフィール

  DIPHENYL CHLOROARSINE is incompatible with strong oxidizing agents, amines, and alkalis. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

• 健康ハザード

  Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• 火災危険

  Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.

• 安全性プロファイル

  A human poison by inhalation. Poison experimentally by inhalation and skin contact. A powerfully irritating military poison. Exposure yields cold-like symptoms, plus headache, vomiting and nausea. A nonpersistent gas. Decontamination is by use of chlorine or caustic soda in confined spaces. When heated to decomposition it emits toxic fumes of As and Cl-. See also ARSENIC COMPOUNDS.
