【Reactivities and Incompatibilities】
Zirconium powder reacts exothermically with many other elements, including hydrogen, boron, carbon, nitrogen, and the halogens. ... The reaction between zirconium powder and platinum is especially violent.
Potassium nitrate, oxidizers [Note: Fine powder may be stored completely immersed in water].
When a mixture of alkali hydroxide and zirconium is heated, the liberated oxygen reacts explosively with the zirconium.
/Alkali metal salts/ will react violently, even explosively, with an excess of zirconium powder and yield the impure metal.
A mixture of hydrated borax and zirconium explodes when heated.
An explosion occurred when zirconium sponge was placed in a beaker of carbon tetrachloride.
Zirconium explodes violently with cupric oxide or lead oxide.
A mixture of powdered zirconium and potassium nitrate explodes when heated above the melting temperature.
Dusts of... zirconium... when suspended in carbon dioxide atmospheres are ignitable and explosive.
The affinity of zirconium for oxygen is great, particularly when the metal is finely divided, and extends to many oxygen-containing compounds. The vigorous reactions with potassium chlorate, potassium nitrate, copper (II) oxide or lead oxide might be anticipated, but there are also explosive reactions with the combined oxygen when zirconium is heated with alkali-metal hydroxides or carbonates, or even zirconium hydroxide. Hydrated sodium tetraborate behaves similarly. Several alkali-metal oxosalts (chromates, dichromates, molybdates, sulfates, tungstates) react violently or explosively when reduced to the parent metals by heating with zirconium.
Powder damp with 5-10% of water may ignite, and although 25% of water is regarded as a safe concentration, ignition of a 50% paste on breakage of a glass container has been observed. Although water is used to prevent ignition, the powder, once ignited, will burn underwater (88.8% oxygen) more violently that in air (21% oxygen). The relatively minor part played by steam and zircalloy fuel containment cans (ruptured by the steam explosion) to form hydrogen towards the end of the catastrophic sequence involved in the Chernobyl nuclear reactor accident is noted in a comprehensive account of the causes of the disaster.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.

Ductile, pure zirconium is made by a two-stage sodium reduction of zirconium tetrachloride in which the tetrachloride and sodium are continuously fed into a stirred reactor to form zirconium dichloride; heating with additional sodium yields zirconium metal. Leaching with water removes the sodium chloride from the zirconium. Bomb reduction of pure zirconium tetrafluoride with calcium also produces pure metal.

Environmental Fate and Exposure Potential

【Environmental Fate/Exposure Summary】
Zirconium is the 20th most common element present in the earth's crust and is found in concentrations ranging from 150 to 300 mg/kg. Zirconium occurs in the minerals zircon, malacon, baddeleyite, zirkelite, eudialyte. It is also found frequently in the rare-earth minerals and in monazite sand. Zirconium in found in S-type stars and has been identified in the sun and meteorites. Lunar rocks were found to contain high concentrations of zirconium oxide as compared with terrestrial rocks. The use and production of zirconium metal in the aviation, aerospace, chemical and surgical instrument industries, and in nuclear reactor technology may result in the release of zirconium to the environment through various waste streams. In general, metal cations in solution are attracted to the negatively charged surfaces of soil particles. The extent of adsorption of metal ions to soils depends on the pH, the mineral content, and organic content of the soil. (SRC)
