Nitrate and Nitrite Compounds, Inorganic

Strong Oxidizing Agent

Mixtures of metal/nonmetal nitrates, such as ZIRCONIUM NITRATE, with alkyl esters may explode owing to the formation of alkyl nitrates; mixtures of a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Dissolves in water to give an acid solution.

Dangerous explosion risk in contact with organic materials.

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

Strong oxidizing agent

Excerpt from ERG Guide 140 [Oxidizers]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 140 [Oxidizers]: Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers. SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area. SMALL LIQUID SPILL: Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Following product recovery, flush area with water. (ERG, 2016)

If material not involved in fire: Keep sparks, flames, and other sources of ignition away and keep material out of water sources and sewers.|Personnel protection: Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.|SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

IDENTIFICATION AND USE: Zirconium nitrate is a white hygroscopic crystal. It is used as a reagent and preservative. Also, it is used in pre-coatings applied on glass surfaces before the application of phosphor photo binder in the production of cathode-ray tubes. Zirconium nitrate has been identified as being used in hydraulic fracturing as a cross linker. HUMAN EXPOSURE AND TOXICITY: No human studies were found for this chemical. ANIMAL STUDIES: Zirconium nitrate has relatively low acute toxicity LD50 (rat oral 2290 mg/kg). Tested in vivo, zirconium nitrate was the most effective of 6 zirconium compounds in decreasing retention of (144) Cerium by liver and femur of rats. None affected strontium retention by tibia or femur. In vitro zirconium nitrate produced a slight inhibition of amylase activity at 0.53 mM concentration, a 20% inhibition of yeast invertase at 0.7 mM, and a 50% inhibition of serum alkaline phosphatase at 0.9 mM, but no inhibition of trypsin at 1 mM concentration. The rather low inhibitory effects produced on these enzymes at the zirconium concentrations used indicate no specific effect of zirconium on these particular enzymes.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 268 workers (none of these were female) were potentially exposed to zirconium nitrate in the US(1). Occupational exposure to zirconium nitrate may occur through inhalation of dust and dermal contact with this compound at workplaces where zirconium nitrate is produced or used(SRC).

Has only a mild pharmacological action. Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation. (USCG, 1999)

INHALATION: Move to fresh air. INGESTION: Give large amount of water. EYES or SKIN: Flush with water. (USCG, 1999)

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration.
