When ARSENIC CHLORIDE is heated to decomposition or on contact with mineral acids, it emits highly toxic fumes of hydrogen chloride and of metallic arsenic. Explodes with Na, K, and Al on impact [Sax, 9th ed., 1996, p. 275]. The interaction of hexafluoroisopropylideneaminolithium with a range of chlorinated and /or fluorinated derivatives of arsenic, boron, phosphorus, silicon, and sulfur yielded a violently exothermic reaction.

When in contact with active metals such as arsenic, iron, aluminum, zinc, or when heated to decomposition, it emits highly toxic fumes of arsenic. Upon contact with water hydrogen chloride is produced. Water causes it to decompose to yield arsenic acid and hydrochloric acid. Avoid active metals such as arsenic, iron, aluminum, zinc, decomposed by water to form arsenic hydroxide and hydrogen chloride. Avoid air, ultraviolet light. Hazardous polymerization may not occur. (EPA, 1998)|Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with water or metals.

Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Arsenic trichloride is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs.|Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 1 lb or 0.454 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

A solid waste containing arsenic trichloride may become characterized as a hazardous waste when subjected to the Toxicant Extraction Procedure listed in 40 CFR 261.24, and if so characterized, must be managed as a hazardous waste.

highly toxic

/Protect/ from exposure those individuals with diseases of skin, blood, liver, kidney, and central nervous system.

Arsenic chloride is produced from dry etching process of gallium arsenide wafers in chlorofluorocarbons and is contained in the wastes recovered from the vacuum system after the processing.

It can cause death. In acute exposures, it is extremely toxic and caustic, owing not only to the poisonous nature of arsenic, but also to the release of hydrochloric acid in the presence of water. Exposure to the skin causes local irritation and blisters. Inhalation or ingestion causes hemorrhagic gastroenteritis resulting in loss of fluids and electrolytes, collapse, shock and death. Chronic poisoning can lead to peripheral nerve damage, skin conditions, liver damage and it has been implicated in the induction of skin and lung cancer. The fatal human dose is 70-180 mg depending on the weight of the victim. (EPA, 1998)|Carcinogens

Warning: Effects usually appear within 30 minutes of exposure but may be delayed for several hours. Caution is advised. Signs and Symptoms of Acute Arsenous Trichloride Exposure: Dehydration, intense thirst, vomiting, severe abdominal pain, and diarrhea are among the first signs and symptoms of acute arsenous trichloride exposure. Hypotension (low blood pressure) and tachycardia (rapid heart rate) are common. Headache, conjunctivitis (red, inflamed eyes), runny nose, and lacrimation (tearing) may also be seen. Garlic odor to the breath and feces may be noted. Cardiovascular signs include shock, ventricular fibrillation, tachycardia, and other cardiac abnormalities. Pulmonary edema may occur. Altered mental status, seizures, and delirium are further complications of acute arsenous trichloride exposure. Intense muscular cramping is common. Contact with airborne dust can result in the release of hydrochloric acid and is generally accompanied by irritation of exposed skin, eyes, and mucous membranes. Emergency Life-Support Procedures: Acute exposure to arsenous trichloride may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination. Inhalation Exposure: 1. Move victims to fresh air. Emergency personnel should avoid self-exposure to arsenous trichloride. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 4. RUSH to a health care facility. Dermal/Eye Exposure: 1. Remove victims from exposure. Emergency personnel should avoid self- exposure to arsenous trichloride. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Remove contaminated clothing as soon as possible. 4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes. 5. Wash exposed skin areas THOROUGHLY with soap and water. 6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 7. RUSH to a health care facility. Ingestion Exposure: 1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 3. DO NOT induce vomiting. 4. Give the victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should be given only if victims are conscious and alert. 5. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water. 6. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults. 7. RUSH to a health care facility. (EPA, 1998)

Analysis of biological samples (blood, serum, feces, urine, leaves, and animal organs) and environmental samples (soils, rocks, dusts, paints, lava) in the presence of 33 other elements. Parr Bomb digestions for non-silacaceous samples used HNO3/HClO4; silicaceous samples required HF/HNO3. The wavelength for arsenic was 193.6960 nm; Chloride was 725.53 nm.
