Agent Name

Antimony pentafluoride

CAS Number

7783-70-2

Formula

F5-Sb

Major Category

Toxic Gases & Vapors

Synonyms

Antimony (V) fluoride; Antimony fluoride; Pentafluoroantimony; [ChemIDplus]

Category

Other Toxic Gases & Vapors

Description

Viscous liquid with a sharp odor; [HSDB]

Sources/Uses

Used as a catalyst and fluorinating agent; [HSDB]

Comments

Hydrofluoric acid formed when F5-Sb reacts with water; Corrosive to eyes, skin, and respiratory tract; Can cause acute pulmonary edema after heavy inhalation exposure; In chronic inhalation studies of animals, pneumonitis as well as liver and cardiac damage are observed. Repeated exposures to flouride compounds can result in fluorosis. [HSDB] Recent experiments show that "there is essentially very little HF formation; the substance was quite unreactive in water." [CAMEO] See "FLUORIDES." See "Antimony" and linked occupational diseases.

Exposure Assessment
BEI

Fluorides in urine = 2 mg/L prior to shift or 3 mg/L at end of shift; (Repeated measurements recommended.)

Dangerous When Wet

Yes - A material that, by contact with water, is liable to become spontaneously flammable or to give off flammable or toxic gas at a rate greater than 1 L per kilogram of the material, per hour; [ERG 2004]

TLV (ACGIH)

0.5 mg/m3, as Sb (2.5 mg/m3, as F)

0.5 mg/m3, as Sb (2.5 mg/m3, as F)

MAK

1 mg/m3, as F, inhalable fraction

IDLH (NIOSH)

50 mg/m3, as Sb

Lethal Concentration

LC50 (mice) = 270 mg/m3
