GHS Classification: Oxidizing solids (Category 2), Acute toxicity – Oral (Category 4), Eye irritation (Category 2A)
Signal Word: Danger
Hazard Statements: May intensify fire; oxidizer. Harmful if swallowed. Causes serious eye irritation.
Pictograms: Flame over circle, Exclamation mark
Potential Health Effects: Swallowing causes nausea, vomiting, and abdominal pain. Dust or solution contact irritates the eyes and may result in redness, watering, or even serious injury. Prolonged or repeated contact with skin may cause mild irritation or dermatitis. Inhalation of dust produces respiratory distress.
Precautionary Statements: Keep away from heat, sparks, flame. Avoid breathing dust, avoid direct skin or eye contact, do not eat or drink while handling. Wash thoroughly after use.
Bismuth Nitrate Pentahydrate: 98-100%
Chemical Formula: Bi(NO3)3·5H2O
CAS Number: 10035-06-0
EC Number: 233-118-8
Impurities: Trace constituents do not represent additional hazards under normal conditions of use.
Inhalation: Move to fresh air. If symptoms develop such as cough or shortness of breath, seek medical attention immediately. Oxygen or artificial respiration may be required if breathing is difficult.
Eye Contact: Flush immediately under running water for at least 15 minutes lifting upper and lower eyelids occasionally. Remove contact lenses if present. Get medical attention immediately.
Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with soap and running water for at least 15 minutes. Seek medical help if irritation develops or persists.
Ingestion: Rinse mouth with clean water. Provide fresh water to drink if the person is conscious. Do not induce vomiting. Seek medical advice immediately and provide details of the chemical ingested.
Important Symptoms/Effects: May cause gastrointestinal upset, dizziness, headache, nausea, and eye irritation.
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide. Bismuth nitrate can intensify fires if mixed with combustible materials.
Unsuitable Extinguishing Media: Avoid dry chemical fire extinguishers containing ammonium compounds; contact could create explosive nitrogen triiodide.
Special Hazards: Bismuth nitrate is a strong oxidizer. Contact with flammable material may cause fire. Decomposition under heating releases toxic gases such as nitrogen oxides and bismuth vapors.
Protective Equipment: Wear full protective suit and self-contained breathing apparatus. Emergency responders must prevent run-off from entering drains or natural water sources.
Additional Information: Fire residues and contaminated fire-fighting water must be disposed of in accordance with local regulations.
Personal Precautions: Evacuate unprotected personnel. Wear appropriate personal protective equipment such as gloves, safety goggles, and a laboratory coat. Avoid creating and breathing dust.
Environmental Precautions: Prevent product from entering drains, surface water, and soil. Notify authorities if extensive environmental contamination occurs.
Methods for Cleanup: Sweep up or use a suitable vacuum to collect spilled material without producing dust. Place in a properly labeled, sealed waste container for safe disposal. Wash spill site with plenty of water. Ventilate the area thoroughly.
Decontamination: Clean the affected surfaces with copious amounts of water to minimize risk of residue.
Handling: Always handle in a well-ventilated area or under local exhaust ventilation. Avoid inhaling dust or direct contact with powder. Do not mix with flammable or readily oxidizable materials.
Storage: Store in original tightly closed container, away from moisture and incompatible substances (such as organic materials, reducing agents, combustibles). Keep containers in a cool, dry, ventilated space away from heat and sunlight.
Special Considerations: Separate from other chemicals, especially strong acids, bases, and combustible substances.
Storage Temperature: Maintain storage temperature below 25°C. Avoid freezing and excessive temperature fluctuations.
Container Requirements: Use containers made from materials compatible with oxidizers, such as glass or certain plastics.
Occupational Exposure Limits: No OSHA or ACGIH exposure limits have been established for bismuth nitrate. Follow workplace and national recommendations for similar oxidizing dusts.
Engineering Controls: Use local exhaust ventilation or chemical fume hood to limit exposure to airborne dust. Maintain eye wash stations and safety showers nearby.
Personal Protective Equipment: Wear tightly fitted chemical safety goggles, laboratory gloves (nitrile, neoprene, or PVC), and a long-sleeved laboratory coat. For dust-generating operations, use a NIOSH-approved particulate respirator.
Additional Hygiene Measures: Change contaminated clothing promptly. Wash hands and face after handling and before eating or drinking.

Partition Coefficient (n-octanol/water): Not meaningful for inorganic compounds
Flash Point: Non-flammable, strong oxidizer
Other Data: Loses water on heating; emits toxic fumes on decomposition.
Chemical Stability: Stable under standard temperature and pressure in sealed containers, but decomposes when exposed to heat or moisture.
Reactivity: Reacts with reducing agents, organic materials, powdered metals. Promotes rapid combustion of combustible substances.
Conditions to Avoid: Heat, open flame, humidity, and direct sunlight.
Incompatible Materials: Strong bases, strong acids, combustible or organic chemicals, metals in powder form.
Hazardous Decomposition Products: Nitrogen oxides, bismuth oxide, toxic metal fumes.

Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Ingestion may produce nausea, vomiting, diarrhea, abdominal pain. High doses could cause kidney and liver effects.
Chronic Toxicity: Extended or repeated exposure may damage organs (liver, kidneys) based on effects reported for soluble bismuth compounds.
Skin/Eye Contact: Eye contact produces severe irritation. Skin contact results in redness or dermatitis.
Sensitization: No known sensitization in humans.
Carcinogenicity: Bismuth compounds are not classified as carcinogens by IARC, NTP, ACGIH, or OSHA.
Reproductive Effects: Data on reproductive toxicity for bismuth nitrate is limited; handle with care as with other heavy metals.
Other Information: Symptoms may occur after several hours, so medical observation for at least 24 hours is advised after exposure.
Ecotoxicity: Harmful to aquatic life with long lasting effects. May cause damage to aquatic organisms even at low concentrations.
Persistence and Degradability: Inorganic compound; not expected to biodegrade.
Bioaccumulation Potential: Bismuth is a heavy metal; can accumulate in soil and aquatic environments.

Other Adverse Effects: Avoid uncontrolled environmental release; large spills require notification to appropriate government agencies.
Waste Treatment Methods: Collect and store in properly labeled containers. Dispose of in accordance with national and local regulations for hazardous chemical waste.
Contaminated Packaging: Containers must be fully emptied and decontaminated before reuse or discarding.
Special Disposal Precautions: Consult local authorized hazardous waste disposal company. Incinerate only if facility is authorized to handle metal and nitrate-containing residues.
