V       HEALTH HAZARD INFORMATION



Threshold Limit Value (TLV): OSHA/PEL for insoluble Mo compounds is 15 mg/m3. TLV for Mo and it’s insoluble Mo com-

pounds (as Mo) is 10 mg/m3.



Effects of Over Exposure: Insoluble molybdenum compounds cause only transient irritation of mucous membranes. Persons with

obstructive airway diseases may suffer aggravation of symptoms from Mo2C dust. Insoluble molybdenum compounds have low oral

toxicity. Not classified as a primary skin irritant. No data available on long term affects.
