Physical and Chemical Properties

Appearance

Zirconium nitrate is a white crystalline solid.

Solubility in water

Very soluble

Density

>1 g/cm3 (20 C) (solid)

Usage

Reagent.

First Aid Measures

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.

Handling and Storage

Storage

Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat, organic materials, and water.

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.

Hazards Identification

Inhalation

Respiratory depression and cyanosis may be noted, due to methemoglobinemia.

Skin

Cyanosis that minimally responds to oxygen therapy may be noted, and is indicative of probable methemoglobinemia.

Eyes

Visual field defects have been reported in sodium nitrite poisoning.

Ingestion

Initial effects of ingestion are gastric irritation with nausea, vomiting and abdominal pain.

Hazards

May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.

Exposure Controls/Personal Protection

Personal Protection

Niosh-certified respirator; goggles or face shield; protective gloves

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Throbbing headache is common. Seizures have been reported following severe intoxication. Behavioral deficits were observed in the adult offspring of rats who received sodium nitrite prenatally.

Fire Fighting Measures

Fire Fighting

Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

Fire Potential

Dangerous fire risk in contact with organic materials.

Accidental Release Measures

Small spills/leaks

Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7).

Stability and Reactivity

Stability

Dangerous explosion risk in contact with organic materials.

Incompatibilities

May react explosively.

Decomposition

On decomposition it emits toxic fumes of nitrogen oxides.

Combustion Products

Toxic oxides of nitrogen may form in fire.
