Section 8: Exposure Controls/ Personal Protection

Control parameters: Occupational exposure limits: OSHA Permissible Exposure Limit (PEL): 5 mg/m 3 for soluble molybdenum compounds as Mo. 15 mg/m 3 total dust, for insoluble molybdenum compounds as Mo. ACGIH Threshold Limit Value (TLV): Molybdenum, metal and insoluble compounds, inhalable fraction, as Mo: 10 mg/m 3 Molybdenum, metal and insoluble compounds, respirable fraction, as Mo: 3 mg/m 3 Molybdenum, soluble compounds, respirable fraction, as Mo: 0.5 mg/m 3 , A3 - Confirmed animal carcinogen with unknown relevance to humans. Exposure controls: Appropriate engineering controls: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Individual protection measures, such as personal protective equipment: Eye/face protection: Use chemical safety goggles and/or full-face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick drench facilities in work area. Hand protection: Use chemical resistant gloves. Examples of preferred glove barrier materials include: Butyl rubber, Neoprene, Nitrile/butadiene rubber, Polyethylene, Ethyl vinyl alcohol laminate, polyvinyl alcohol, Polyvinyl chloride. Body protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. Respiratory protection: If the exposure limit is exceeded and engineering controls are not feasible, (NIOSH Approved) a full facepiece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator.
