Hazards and Protection.
Storage
Do not store exposed to direct light. Do not allow moisture or water contamination of product. Store in closed containers in a dry, well-ventilated area.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed. Avoid creating and breathing dust. Use dustless systems for handling, storage, and clean up so that airborne dust does not exceed the PEL. Use adequate ventilation and dust collection. Practice good housekeeping.
Protection
Nisoh certified respirator; rubber gloves; chemical goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Add soda ash (Na2CO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stability
Stable.
Incompatibilities
Reacts as bases to neutralize acids.
Decomposition
When heated to decomposition it emits acrid smoke and fumes of zinc oxide.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Fire potential
Not flammable
Hazards
Some may burn but none ignite readily. May polymerize explosively when heated or involved in a fire. Containers may explode when heated. Some may be transported hot.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
   Ingestion
Ingestion - zinc salts (especially zinc sulfate) produce gastritis ranging from a burning pain in the mouth and throat to intense gastric and substernal pain, strictures, violent vomiting, diarrhea, shock, and possible death.
   Inhalation
Inhalation of material may be harmful.
   Skin
Contact may cause burns.
   Eyes
See Skin.

First aid
 
   Ingestion
Induce vomiting, followed by prompt and complete gastric lavage, cathartics, and demulcents.
   Inhalation
Move to fresh air; if exposure is severe, get medical attention.
   Skin
Wash with soap and water.
   Eyes
Flush with water for at least 10 min.; consult physician if irritation persists.
