SECTION VIII. HANDLING PRECAUTIONS
Personal Protective Equipment
Respirators If exposure cannot be maintained at or below established OSHA guidelines, respiratory protection must be provided in accordance with 29 CFR 1910.134 requirements.
Skin Protection Wear appropriate protective clothing and chemical resistant gloves as needed to prevent skin contact. Consult manufacturer to determine appropriate type of gloves or clothing for your particular application. Clean contaminated clothing and protective equipment before reuse. Wash thoroughly after handling material.
Ventilation Provide local exhaust or process enclosing ventilation to maintain exposures below OSHA guidelines 29 CFR 1910.1000 subpart 7.
GENERAL GUIDELINES
Known concentrations <PEL* with oxygen levels >19.5%. No respirator is required. Known concentrations >PEL* <IDLH* with oxygen levels >19.5%. Air purifying full-face piece respirator with high-efficient particulate filters.
Unknown concentration and/or IDLH* and/or oxygen levels <19.5%. Self-contained breathing apparatus with full face piece operated in pressure-demand or other positive pressure mode. Supplied-air respirator with full-face piece operated in pressure demand or other positive pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode.
--------------------------------------------------------------------------------

SECTION IX. SPILL OR LEAK PROCEDURES
Spills and Leaks Comply with Federal, State and local regulations on reporting spills. Confine spill or leak to as small an area as possible. Vacuum or shovel spilled material into clean, dry containers and dispose of according to Federal, State and local regulations. Zinc Sulfate Solutions should be flushed with plenty of water to an approved chemical sewer.
Waste Disposal Comply with Federal, State and local regulations. Zinc Sulfate Solutions can be carefully reacted with Sodium Carbonate to form an insoluble Zinc Carbonate solid that can be scooped up and sent to a disposal contractor.
--------------------------------------------------------------------------------

SECTION X. SPECIAL PRECAUTIONS
Storage Store in a cool dry place.
Other Precautions Do not take internally.
