Stibine

Agent Name
Stibine
CAS Number
7803-52-3
Formula
H3-Sb
Major Category
Toxic Gases & Vapors
Synonyms
Antimony hydride; Antimony trihydride; Hydrogen antimonide; [NIOSH] UN2676
Category
Hydrides
Description
Colorless gas with a disagreeable odor like hydrogen sulfide; [NIOSH] Antimony hydride is 4 times as heavy as air--accumulates in low-lying areas; [ACGIH]
Sources/Uses
Stibine gas may be formed during battery overcharging or when antimony compounds come in contact with an acid plus a reducing substance such as zinc. Stibine is used as a dopant in the microelectronics industry. Has been used as a fumigant; [ACGIH]
Comments
A few cases of occupational stibine poisoning have been reported. Like arsine, stibine is a hemolytic agent that also injures the kidneys and liver. [ACGIH] A respiratory tract irritant that may have effects on the blood (hemolysis), liver, kidneys, and CNS; [ICSC] Liquefied gas may cause burns or frostbite; [CAMEO] Animals exposed to lethal concentrations develop anemia, hemoglobinuria, and acute renal failure.
