EXPOSURE


 •INHALATION Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest.
 •SKIN Redness.
Protective gloves.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating (at 965C), producing molybdate oxide fumes.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Mo, insoluble compounds, respirable fraction 3 mg/m as TWA TLV: Mo, insoluble compounds, inhalable fraction 10 mg/m as TWA (ACGIH 2006).
