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
Clothing contaminated with zirconium oxychloride, zirconyl acetate, or zirconium tetrachloride should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of containment from the clothing.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stability
No data.
Incompatibilities
Reacts as acid to neutralize bases.

Fire.
Fire fighting
Use appropriate media to fight supporting fire. Contain runoff.

Exposure effects
Experimental animals exposed to massive doses have developed CNS depression. Two individuals administered 50 milligrams of zirconium malate intravenously developed vertigo. Small fractions of zirconium were absorbed in female rats by the oral route, and the metal seemed to concentrate in the ovaries and produce hypervascularization. <br>In mice, offspring of clams who received zirconium during pregnancy had long-lasting behavioral changes. <br>Zirconium is found in newborn rats. <br>In rats, zirconium appears in the breast milk.
   Ingestion
Ingestion of certain zirconium salts may cause irritant or caustic effects.
   Inhalation
Pulmonary abnormalities have not been demonstrated in workers with zirconium fume exposure for 1 to 5 years.
   Skin
Dermal exposure to zirconium in topical poison ivy medications and deodorants has caused subcutaneous granulomas, probably due to a hypersensitivity reaction.

First aid
 
   Ingestion
Give large amount of water.
   Inhalation
Move to fresh air.
   Skin
Flush with water.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
