Hazards and Protection.
Storage
Keep tightly closed in a cool place in a tightly closed container.
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.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas.
Stability
Stable.
Incompatibilities
Reacts similarly as does other alkali-metal oxosalts(chromates, dichromates, molybdates, sulfates, tungstates),.

Fire.
Fire fighting
DO NOT USE WATER, FOAM OR carbon dioxide. Dousing metallic fires with water may generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment (i.e., building, cargo hold, etc.). Use DRY sand, graphite powder, dry sodium chloride based extinguishers, G-1 or Met-L-X powder. Confining and smothering metal fires is preferable rather than applying water. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: If impossible to extinguish, protect surroundings and allow fire to burn itself out.
Fire potential
Flammable/combustible material.
Hazards
May react violently or explosively on contact with water. Some are transported in flammable liquids. May be ignited by friction, heat, sparks or flames. Some of these materials will burn with intense heat. Dusts or fumes may form explosive mixtures in air. Containers may explode when heated. May re-ignite after fire is extinguished.

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.
   Eyes
Zirconium and its compounds are eye irritants.

First aid
 
   Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes.
   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.
