General Description
A colorless odorless liquid. Density 1.654 g / cm3. Used as a lachrymator poison gas. Toxic by inhalation and skin absorption.
Air & Water Reactions
Reacts with water or with moist air to form hydrochloric acid [AAR 1991].
Reactivity Profile
PHENYL DICHLOROARSINE is incompatible with acids and bases. A reducing agents and therefore generally incompatible with oxidizing agents.
Health Hazard
Median lethal dosage 2600 mg-minute/m3. Mean incapacitating dosage 16 mg-minute/m3 as a vomiting agent and 1800 mg-minute/m3 as a blistering agent. 633 mg-minute/m3 produces eye injury. Poisonous; may be fatal if inhaled, swallowed, or absorbed through skin. Contact may cause burns to skin and eyes. Strong irritant to eyes, skin, and issue.
Fire Hazard
PHENYL DICHLOROARSINE may burn but does not ignite readily. Containers may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Upon decomposition hydrogen chloride and phenylarsenious oxide are emitted. Unstable. Decomposed by water.
Potential Exposure
Phenyldichloroarsine is an organoarsenic compound used in organic synthesis and as a solvent. PD has been used as a military tear gas, vesicant and blister agent.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material from skin is of extreme importance. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Keep victim quiet and maintain normal body temperature. Effects may be delayed; keep victim under observation.
Shipping
UN3280 Organoarsenic compound, liquid, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required, Potential Inhalation Hazard (Special Provision 5). UN1556 Arsenic compounds, liquid, n.o.s. inorganic, including arsenates, n.o.s.; arsenites, n.o.s.; arsenic sulfides, n.o.s.; and organic compounds of arsenic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. Military driver shall be given full and complete information regarding shipment and conditions in case of emergency. AR 50-6 deals specifically with the shipment of chemical agents. Shipments of agent will be escorted in accordance with AR 740-32.
Incompatibilities
Contact with water forms HCl. Heat produces fumes of arsenic and chlorine. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some metals in the presence of moisture
Chemical Properties
Phenyldichloroarsine is a colorless or light yellow liquid or gas. Odorless.
