Standards and Recommendations
OSHA PEL: TWA 0.5 mg(As)/m3
DOT Classification: 6.1; Label: Poison
Specification
1.General Description : Strongly irritating to skin and eyes. Toxic by ingestion and inhalation.
2.Air & Water Reactions: Slowly decomposed by water
3.Reactivity Profile : 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
4.Health Hazard :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.
5.Fire Hazard: 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.
