Ferrovanadium dust

Airborne particulate from ferrovanadium alloy production, handling, and processing.

Airborne form

dust

The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.

Evidence

The current NIOSH Pocket Guide describes ferrovanadium as dark, odorless particulate dispersed in air, identifies a 1 mg/m³ time-weighted-average REL and 3 mg/m³ short-term limit, and reports eye and respiratory irritation with bronchitis and pneumonitis in animals.

NIOSH REL TWA 1 mg/m³ ST 3 mg/m³. Physical Description Dark, odorless particulate dispersed in air. Exposure Routes inhalation, skin and/or eye contact. Symptoms irritation eyes, respiratory system; In Animals: bronchitis, pneumonitis.

NIOSH identifies ferrovanadium as a dark particulate alloy, usually containing 50–80% vanadium, and lists a 1 mg/m³ REL with a 3 mg/m³ short-term limit.
