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.
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)
General First Aid:
· Call 911 or emergency medical service.
· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.
· Move victim to fresh air if it can be done safely.
· Administer oxygen if breathing is difficult.
· If victim is not breathing:
-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.
-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).
-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.
· Remove and isolate contaminated clothing and shoes.
· For minor skin contact, avoid spreading material on unaffected skin.
· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.
· For severe burns, immediate medical attention is required.

Arsenic and its metabolites disrupt ATP production through several mechanisms. At the level of the citric acid cycle, arsenic inhibits pyruvate dehydrogenase and by competing with phosphate it uncouples oxidative phosphorylation, thus inhibiting energy-linked reduction of NAD+, mitochondrial respiration, and ATP synthesis. Hydrogen peroxide production is also increased, which might form reactive oxygen species and oxidative stress. Arsenic's carginogenicity is influenced by the arsenical binding of tubulin, which results in aneuploidy, polyploidy and mitotic arrests. The binding of other arsenic protein targets may also cause altered DNA repair enzyme activity, altered DNA methylation patterns and cell proliferation. (T1, A17)
Classification of carcinogenicity: 1) evidence in humans: sufficient; 2) evidence in animals: limited. Overall summary evaluation of carcinogenic risk to humans is Group 1: Carcinogenic to humans. NOTE: This evaluation applies to the group of chemicals as a whole and not necessarily to all individual chemicals within the group. /Arsenic and arsenic compounds/
CLASSIFICATION: A; human carcinogen. BASIS FOR CLASSIFICATION: Based on sufficient evidence from human data. An increased lung cancer mortality was observed in multiple human populations exposed primarily through inhalation.

IT IS EXTREMELY TOXIC & CAUSTIC, OWING NOT ONLY TO POISONOUS NATURE OF ARSENIC BUT ALSO TO RELEASE OF HYDROCHLORIC ACID IN PRESENCE OF WATER. ... INDUSTRIALLY /VAPOR/ HAS BEEN OBSERVED TO CAUSE BLEPHAROSPASM, PHOTOPHOBIA, & LACRIMATION IN WORKMEN, RESULTING IN TEMPORARY REDDENING OF CONJUNCTIVA, BUT NO CORNEAL INJURY.
AUTOPSY ON 24 YR OLD CHEM ENGINEER WHO COMMITTED SUICIDE BY MEANS OF ARSENIC TRICHLORIDE REVEALED ACUTE ARSENIC POISONING. EXTREME CORROSION FOUND, ESPECIALLY IN REGION OF ESOPHAGUS.
Arsenic trichloride was tested in human leukocyte cultures at concn of 6, 24, and 72x10-7 M. It significantly incr the number of chromosomal aberrations in a concn dependent manner producing 11.7, 70.5 and 125.0 aberrations per 100 cells, respectively.
Arsenic trichloride was /accidentally/ spilled on one leg of a worker. After death, arsenic was found in high concentrations in all tissues examined (lung, liver, kidney, pancreas, stomach, heart, and blood), and it appeared that the trichloride had been inhaled as well as absorbed through the skin. The heart, liver, kidneys, pancreas, and stomach were in a state of acute granulo-fatty degeneration. The direct cause of death was kidney failure, but the damage to the lung, liver, pancreas, and heart also would have been fatal.
Exposure to arsenic trichloride, which has a vapor pressure at 25C sufficient to produce an air concn of 140,000 mg/m3, can cause irritation or ulceration on contact or may be absorbed through the skin, with fatal results ... .
/Protect/ from exposure those individuals with diseases of skin, blood, liver, kidney, and central nervous system.
This substance may be hazardous to the environment. Special attention should be given to soil organisms and aquatic organisms. It is strongly advised not to let the chemical enter into the environment.
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.

/GUIDE 157: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE/WATER -SENSITIVE)/ Health: TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns, or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat which will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
/GUIDE 157: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE/WATER -SENSITIVE)/ Fire or Explosion: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or contaminated with water.
