Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry.
Stability
No data.
Incompatibilities
Reacts explosively with alcohols (methanol, ethanol), bromine, chlorine or liquefied sulfur dioxide Reaction with water, nitro compounds, arsenic trichloride, phosphorus trichloride is violent.

Fire.
Flash Point,°C
-40
Autoignition, °C
-18
Fire fighting
Do not extinguish fire unless flow can be stopped. Do not use water. Use graphite, soda ash or powdered sodium chloride.
Fire potential
Flammable/combustible material.
Hazards
May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. May react vigorously or explosively on contact with water. May decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished.
Combustion products
Yields zinc oxide fumes when burning. Reacts spontaneously with air or oxygen, and violently with water, evolving flammable ethane gas.

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 decomposition products may cause severe injury or death.
   Skin
Hives may rarely occur.
   Eyes
See Skin.

First aid
 
   Ingestion
Do NOT induce vomiting; have victim drink large amounts of water or milk immediately; if vomiting occurs, give more fluids; get medical attention.
   Inhalation
Move victim to fresh air and call doctor immediately; give mouth-to-mouth resuscitation if needed; keep victim warm and comfortable; oxygen should be given only by experienced person, and only on doctor's instructions.
   Skin
Flush affected area with large amounts of water, do not use chemical neutralizers; get medical attention if irritation persists.
   Eyes
Flush with large amounts of running water for at least 15 min., holding eyelids apart to insure thorough washing; get medical attention as soon as possible; do not use chemical neutralizers, and avoid oils or ointments unless prescribed by doctor.
