7. Handling and Storage
Keep container tightly closed. Suitable for any general chemical storage area. Containers of this material may be
hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions
listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. 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. Please refer to the ACGIH document, Industrial
Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to the substance is apparent, consult an industrial hygienist. For
emergencies, or instances where the exposure levels are not known, use a full-facepiece positive-pressure,
air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to
prevent skin contact.
Eye 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.
