Lithium Nitrate: Taking a Closer Look at Its Material Safety Data

Identification and Why It Matters

Chemical Name: Lithium Nitrate
Common Uses: Heat transfer salts, oxidizing agent in pyrotechnics, specialty glass production
Appearance: White, crystalline solid
Odor: Odorless
Molecular Formula: LiNO₃
CAS Number: 7790-69-4

Hazard Identification: Where Caution Comes In

Main Risks: May cause eye and skin irritation, hazardous if inhaled or swallowed
Oxidizing Nature: Strong oxidizer, can intensify fire in contact with combustible material
Chronic Exposure: May cause thyroid or nervous system effects through repeated contact
Environmental Impact: Harmful to aquatic life in significant concentrations
Signal Words: Danger, due to oxidizing and toxicity risks

Composition / Information on Ingredients

Main Ingredient: Lithium nitrate
Purity: Typically above 98% in industrial and laboratory settings
Other Trace Constituents: May contain minimal residual sodium or potassium salts based on source

First Aid Measures: What to Do in a Pinch

Eye Contact: Immediately rinse eyes with plenty of water for at least 15 minutes, keep eyelids apart
Skin Contact: Wash off with plenty of soap and water
Inhalation: Move to fresh air, supply oxygen if breathing is difficult, seek medical attention if symptoms develop
Ingestion: Rinse mouth, seek medical help right away—ingestion of nitrates can disrupt body’s oxygen balance
Symptoms to Watch: Redness, irritation, dizziness, nausea

Fire-Fighting Measures: Acting with Speed

Fire Risk: Strong oxidizer, intensifies fire with flammable materials
Suitable Extinguishing Media: Water spray, fog—do not use dry chemicals or carbon dioxide on fires involving oxidizers
Combustion Products: May release toxic nitrogen oxides
Protection for Fire Responders: Self-contained breathing apparatus, full protective gear

Accidental Release Measures: Dealing with Spills

Personal Precautions: Avoid contact with skin, eyes, clothing; ventilate area
Environmental Measures: Prevent run-off to drains, sewers, waterways
Cleanup Methods: Sweep up carefully, use non-combustible absorbent, collect in containers for disposal, avoid creating dust

Handling and Storage: Keeping Things Safe

Handling: Wear protective clothing, handle in well-ventilated spaces
Storage: Keep away from heat, sparks, flammable materials; store in tightly closed containers
Condition to Avoid: Moisture, extreme temperatures, incompatible substances like reducing agents, acids

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation, enclose processes where possible
Personal Protective Equipment: Gloves made from neoprene or nitrile, chemical splash goggles, lab coat or apron
Hygiene: Wash hands and face thoroughly after use, avoid eating or drinking near work area
Respiratory Protection: Dust masks or respirators for higher airborne concentrations

Physical and Chemical Properties: Getting the Facts Straight

Physical State: Solid
Color: White
Boiling Point: Decomposes before boiling
Melting Point: Around 251°C
Solubility: Highly soluble in water
Odor: Odorless
Vapor Pressure: Negligible at room temperature
Density: About 2.38 g/cm³

Stability and Reactivity: Avoiding Trouble

Chemical Stability: Stable under normal use and storage
Dangerous Reactions: Violent reaction with reducing agents, organic materials, and combustibles
Hazardous Decomposition Products: Nitrogen oxides
Condition to Avoid: Heat, flame, and contamination by organic or reducing material

Toxicological Information: Effects on Health

Acute Toxicity: Ingestion may affect the gastrointestinal tract, kidneys, nervous system
Chronic Exposure: Reports of effects on thyroid or kidneys after repeated, high exposure
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Symptoms: Dizziness, nausea, blue-tinged skin in extreme cases due to nitrate poisoning

Ecological Information: Watching Over the Environment

Ecotoxicity: Can impact aquatic organisms, especially in large spills
Persistence: Nitrates remain mobile in water, may disturb aquatic balance
Bioaccumulation: Not significant for lithium nitrate
Degradability: Inorganic salt, will remain unless diluted or dispersed

Disposal Considerations: Getting Rid of Waste Right

Waste Methods: Do not dump into ground or surface water
Product Disposal: Treat as hazardous waste; send to licensed disposal or incineration site
Contaminated Packaging: Rinse thoroughly, dispose of as hazardous material if possible

Transport Information

UN Number: Classified as a hazardous material for transport
Hazard Class: Usually listed as an oxidizer
Packing Group: Group II or III, depending on concentration
Shipping Cautions: Keep away from flammable cargo, label clearly

Regulatory Information

Labeling: Must have hazard warnings for oxidizer and toxicity
Workplace Regulations: Occupational exposure limits set in various regions
Environmental Rules: Discharge into environment may be regulated, especially near waterways
Transport: Requires special labeling, carrier notification under international regulations
