Antimony pentasulfide Consensus Reports

Reported in EPA TSCA Inventory. Antimony and its compounds are on the Community Right-To-Know List.

Antimony pentasulfide Safety Profile

Moderately toxic by intraperitoneal route. See also ANTIMONY COMPOUNDS and SULFIDES. Flammable when exposed to heat or by chemical reaction with powerful oxidizers. Use water to fight fire. Moderately explosive when shocked or by spontaneous chemical reaction in contact with powerful oxidizers. When heated to decomposition or on contact with acid or acid fumes it emits highly toxic fumes of oxides of sulfur and antimony. Incompatible with water or steam to produce toxic and flammable vapors and with oxidizers, e.g., Ag(ClO3)2, HClO3, ClO2, Mg(ClO3)2, TlO, Zn(ClO3)2.

Antimony pentasulfide Standards and Recommendations

OSHA PEL: TWA 0.5 mg(Sb)/m3
ACGIH TLV: TWA 0.5 mg(Sb)/m3
NIOSH REL: (Antimony) TWA 0.5 mg(Sb)/m3

Antimony pentasulfide Specification

 Antimony pentasulfide (CAS NO.1315-04-4) is moderate toxic. It may explosive with strong oxidants spontaneously if  vibrated. Antimony pentasulfide (CAS NO.1315-04-4) will burn by the presence of open flame, high temperature and oxidizer. It will produce toxic sulfur oxides and antimony compounds smoke when buring. It also will decomposit toxic gases of nitrogen oxides in the wet environment.
