Antimony hydride toxicity

The most important antimony hydride, stibine, SbH3 is a malodorous, extremely toxic gas (bp -18 °C, mp -88 °C) formed from soluble antimony compounds and hydrogen in... 

ANTIMONY or ANTIMONY BLACK (7440-36-0) Dust or powder forms explosive mixture with air. Reacts violently with strong oxidizers and acids, especially halogenated acids, producing toxic stibine gas (antimony hydride). Reacts violently with anunonium nitrate, bromine, bromine azide, bromine tri fluoride, bromoazide, chloric acid, chlorine, chlorine monoxide, chlorine trifluoride, dichlorine oxide, disulfur dibromide, fluorine, halogens, iodine, iodine pentafluoride, nitrosyl fluoride, nitryl fluoride, potassium dioxide, potassium nitrate, potassium permanganate, potassium peroxide, sodium nitrate, sodium peroxide. Forms explosive V-chlorodimethylamines with chloric and perchloric acid. 

ANTIMONY, REGULUS (7440-36-0) Dust or powder forms explosive mixture with air. Reacts violently with strong oxidizers and acids, especially halogenated acids, producing toxic stibine gas (antimony hydride). Reacts violently with ammonium nitrate, bromine.

Copper sulfate, in small amounts, activates the zinc dust by forming zinc—copper couples. Arsenic(III) and antimony(TTT) oxides are used to remove cobalt and nickel they activate the zinc and form intermetaUic compounds such as CoAs (49). Antimony is less toxic than arsenic and its hydride, stibine, is less stable than arsine and does not form as readily. Hydrogen, formed in the purification tanks, may give these hydrides and venting and surveillance is mandatory. The reverse antimony procedure gives a good separation of cadmium and cobalt. 

SAFETY PROFILE Poison by ingestion and intraperitoneal routes. A trace mineral added to animal feeds. Potentially explosive reaction with charcoal + ozone, metals (e.g., powdered aluminum, copper), arsenic carbon, phosphoms, sulfur, alkali metal hydrides, alkaline earth metal hydrides, antimony sulfide, arsenic sulfide, copper sulfide, tin sulfide, metal cyanides, metal thiocyanates, manganese dioxide, phosphorus. Violent reaction with organic matter. When heated to decomposition it emits very toxic fumes of I and K2O. See also lODATES. 

SAFETY PROFILE Poison by inhalation. Potentially explosive decomposition at 200°C. Flammable when exposed to heat or flame. Explosive reaction with ammonia + heat, chlorine, concentrated nitric acid, ozone. Incompatible with oxidants. The decomposition products are hydrogen and metallic antimony. When heated to decomposition it emits toxic fumes of Sb. Used as a fumigating agent. See also ANTIMONY COMPOUNDS and HYDRIDES. 

DICROTOPHOS (141-66-2) CsHisNOjP Combustible liquid. Explosive mixture formed with air [Flashpoint >175°F/>79°C Fire Rating (isopropanol) 2]. Note May vary depending on carrier solvent used in liquid formulations. Contact with oxidizers may cause the release of toxic phosphorus oxides. May react violently with antimony(V) pentafluoride. Contact with strong reducing agents, including metal hydrides, nitrides, sulfides, alkali metals, and metal alkyls, may cause the formation of...
