Summary: Arsine is a colorless, flammable, and highly toxic gas. After inhalation, arsine rapidly binds to red blood cells, producing irreversible cell membrane damage. Because arsine is nonirritating and produces no immediate symptoms, persons exposed to hazardous levels may be unaware of its presence. This review is Part I of a two-part series focusing on heavy metal toxicity. Since it was written to address the high toxicity and flammability of arsine where the consequences of handling the compressed gas could cause injury, death, and/or facility damage, the CGA G-16-2018 standard provides an understanding of the potential hazards involved in handling arsine and touches upon a breadth of information that can minimize risk potential. Since there is little to no odor at lower doses, Arsine is challenging to detect without using gas detection equipment. Free to read It has a garlic-like or fishy odor that can be detected at concentrations of 0.5 ppm and above. Biological Monitoring of Toxic Metals. It has a garlic-like or fishy odour that can be detected at concentrations of 0.5ppm and above. Arsine poisoning. At low levels, arsine is a potent hemolysin, causing dose-dependent intravascular hemolysis. Part I will cover arsenic and mercury toxicity. Arsine is a non‐polar gas which is soluble in organic solvents but only slightly soluble in water (saturated at 8.93 mM) (Fowler and Weissberg 1974, Klimecki and Carter 1995). Stop flow of gas if safe to do so, while continuing … Information is limited about absorption of arsine (SA) through, or arsine’s (SA) toxic effects on, the skin or eyes. 1968 Apr; 68 (4):853–866.

People exposed to arsine gas may not notice a reaction for several hours, medical officials warned on Wednesday. Arsenic comes in four common valence states: As(o), As(III), As(V) and Arsine gas and three common forms: inorganic salt, organic salt, and gaseous form. 4.2 High risk circumstance of poisoning Most cases of arsine poisoning do not result from use of the gas itself; rather they occur when arsine is accidentally generated as by-product of a chemical reaction involving a metal containing an arsenic impurity and an acid or a strong alkali. 100 taken ill in US gas leak AP Tulsa (Oklahama), July 12, 2001 A VALVE on a chemical tank blew off and released toxic gas, sending nearly 100 people to hospitals with breathing problems and nausea. It is generally shipped in cylinders as a liquefied compressed gas. SbH 3 is an unstable flammable gas. S Afr Med J. Thus an arsine detection system in ppm or ppb should be selected. Ingestion is unlikely because arsine (SA) is a gas at room temperature. Metal arsenides are solids that can be ingested; they can react with stomach acids to release arsine (SA) gas. Use self-contained breathing apparatus (SCBA) and protective clothing. Arsine is water soluble. It is highly toxic, with an LC50 of 100 ppm in mice. Arsenic is an element and is a naturally occurring mineral found widely in the environment. o Initial symptoms may include malaise, headache, dyspnea, weakness, nausea, vomiting, abdominal pain, … A case report. Acute arsine poisoning due to inhalation of arsine gas (AsH3) is rare but has no known antidote. Arsine gas (ASH 3) has been known for centuries to be a potent hemolytic agent but the exact mechanism of this effect is still not understood at the molecular level. Because arsine is nonirritating and produces no immediate symptoms, persons exposed to hazardous levels may be unaware of its presence. Chronic Arsine Toxicity – Most reported cases of arsine poisoning have been acute or sub-acute in nature, usually resulting from a single short exposure or from breathing the gas for a few hours. Arsine gas is the most toxic form of arsenic. It has a garlic-like or fishy odour that can be detected at concentrations of 0.5ppm and above. Customers always need resolution with 0.001ppm. Eight sailors on board the Asiafreighter were exposed to arsine that had escaped from a cylinder in the cargo hold. Arsenic is widely used commercially, a fact that increases the risk of overexposure. First published on 6th December 2004. 1. Despite its garlic fragrance, only an arsine gas detector can accurately measure concentrations of this gas. Arsine is a highly toxic gas that is generated upon exposure of arsenic-containing ores to acids, and it is a by-product of refining of non-ferrous metals. Acute toxic inorganic arsenic exposure and arsine gas exposure can rapidly result in death, and there are only a few ways to possibly save the patient's life. A patient with arsine toxicity has recently been treated by both red blood cell exchange (RBC-E) and plasma exchange (PE) therapy and our experience is reported. Introduction In environmental terms, the 19th century was the age of arsenic. Arsine gas is colorless, nearly odorless and it does not produce tissue irritation. A correlative clinicopathological study with electron microscopic observations. Br J Ind Med, 43(5):353-355, 01 May 1986 Cited by: 3 articles | PMID: 3707874 | PMCID: PMC1007660. Arsine-induced anuria. The clinical presentation, with focus on the nervous, cardiovascular, pulmonary, gastroin … Arsine is a colorless, flammable, and highly toxic gas. Because arsine is nonirritating and produces no immediate symptoms, persons exposed to hazardous levels may be unaware of its presence. In recent years, the use of compounds containing some of the Group III elements and arsenic generated by processes utilizing arsine gas has expanded greatly due to the excellent electrical properties of these materials. Even if it is explosive at 5.1% volume, an LEL measurement would be useless as this gas is highly toxic. The toxicity of trimethylarsine: an urban myth†. Arsine also is used in mining and manufacturing processes involving arsenicals and paints and herbicides containing arsenicals. Top of Page. It has a garlic-like or fishy odor that can be detected at concentrations of 0.5 ppm and above. Four suffered severe toxicity and within a few hours had developed fever, weakness, nausea, vomiting, diarrhoea, abdominal pain, and haemoglobinuria. Arsenic (As) is a nearly tasteless odorless toxic metalloid element that is found ubiquitously in the environment. Arsine is a colorless, flammable, and highly toxic gas. Immediately cool containers with water from maximum distance. Arsine is extremely toxic and a potent hemolytic agent, ultimately causing death via renal failure. Arsine: Human health aspects.

The inlet of each exposure chamber was equipped with a convoluted, stainless-steel, static mixing element, housed in a 2-in., type 3 16, stainless-steel inlet tube After amine was introduced into the process air stream, it flowed through the mixing element into the chamber. Arsine gas poisoning results in a considerably different syndrome from that caused by other forms of arsenic. Rochester Series on Environmental Toxicity. Asymptomatic arsine nephrotoxicity. o After a latent period that may range from 2 to 24 hours post inhalation (depending on the magnitude of exposure), massive intravascular hemolysis may occur. In one report of chronic arsine poisoning, it was noted that arsine in very small concentrations appeared to exert a cumulative, damaging effect. Toxic, flammable liquefied gas Evacuate all personnel from the danger area. 1979 Aug 4; 56 (5):192–194. All exposure victims should be evaluated and observed. Arsine is stored under pressure in glass lined cannisters. New York: Plenum Press; 1988:469-478. Even if arsine’s odor was not detected at the scene, those present could have been seriously exposed. Teitelbaum DT, Kier LC. Hemodialysis can remove arsenic from the bloodstream, but only before it binds to the tissues so there is only a short time window for this treatment to work. Inhalation of over 10 ppm is lethal and at concentrations higher than 25 ppm are reported to be lethal in less than an hour after exposure., while over 250ppm is reported to be instantaneously lethal. The SC-8000 is a single toxic gas detector built for tough as well as demanding environments.
