Classification: Eye irritant, acute toxicity (oral, inhalation)
Hazard Statements: May cause respiratory irritation, eye irritation, skin irritation, nausea, or vomiting if ingested
Label Elements: Signal word "Warning", hazard pictograms for irritants
Precautionary Statements: Avoid inhalation of dust, avoid contact with eyes and skin, wash hands thoroughly after handling, use only in well-ventilated areas
Potential Health Effects: Shortness of breath, coughing, eye redness, irritation or inflammation in case of contact or prolonged exposure
Chemical Name: Ammonium Bicarbonate
CAS Number: 1066-33-7
Concentration: 99 - 100%
Impurities: Traces of ammonia, carbonate species, water, depending on supplier source
Inhalation: Move to fresh air, monitor for breathing difficulty, seek medical attention if symptoms persist
Skin Contact: Rinse thoroughly with water, remove contaminated clothing, consult medical personnel for persistent irritation
Eye Contact: Immediately flush eyes with plenty of running water for several minutes, consult doctor if discomfort continues
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical assistance if unwell
Advice to Physician: Treat symptomatically, monitor for respiratory distress or allergic reaction
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide; avoid large volumes of water as product decomposes to ammonia and carbon dioxide under heat
Specific Hazards: Under fire conditions, decomposition releases ammonia, carbon dioxide; fumes can be irritating or hazardous
Protective Equipment: Wear self-contained breathing apparatus, protective clothing to prevent contact with skin and eyes, ensure good ventilation
Special Procedures: Remove containers from fire area if safe to do so, cool fire-exposed containers with water spray, avoid breathing smoke or gas
Personal Precautions: Wear suitable protective equipment (gloves, goggles, dust mask), avoid dust formation, ensure adequate ventilation
Environmental Precautions: Prevent entry into drains or waterways, contain spills using inert material (sand, earth), avoid environmental contamination
Cleanup Methods: Sweep up spillage, place in suitable closed containers for disposal, ventilate area, wash residues with water if needed
Handling: Minimize dust generation, use appropriate PPE (personal protective equipment) including gloves, goggles, dust mask, practice good industrial hygiene
Storage Conditions: Store in cool, dry, well-ventilated areas away from heat sources, acids, moisture, incompatible materials (acids, strong oxidizers), keep container tightly closed
Technical Measures: Use only non-sparking tools, prevent static discharge, ensure storage area has suitable ventilation
Exposure Limits: No established OSHA, NIOSH, or ACGIH limits for ammonium bicarbonate; consider particulate limits (PEL: 15 mg/m³ total dust, 5 mg/m³ respirable dust)
Engineering Controls: Use local exhaust or general room ventilation to minimize dust exposure
Personal Protective Equipment: Wear safety glasses or chemical splash goggles, disposable gloves (nitrile, latex), lab coats or aprons, dust masks (NIOSH-approved for particulates)
Hygiene Measures: Wash thoroughly after handling, do not eat, drink, or smoke in work area, launder contaminated clothing before reuse
Appearance: White crystalline powder or granules
Odor: Slight ammonia smell
Molecular Weight: 79.06 g/mol
Melting Point: Decomposes above 36 °C (96.8 °F), does not melt as such
Solubility: Soluble in water, insoluble in alcohol, forms basic solution
Density: 1.59 g/cm³
pH: Approximately 7.8 (solution)
Vapor Pressure: Negligible at room temperature
Partition Coefficient: Not applicable
Boiling Point: Not applicable (decomposes before boiling)
Evaporation Rate: Not applicable
Chemical Stability: Stable at room temperature under dry conditions, decomposes on heating releasing ammonia and carbon dioxide
Conditions to Avoid: Heat, moisture, acids, open flames, incompatible materials
Incompatible Materials: Acids, strong oxidizers, moisture, strong bases
Hazardous Decomposition Products: Ammonia, carbon dioxide, water vapor
Reactivity: Reacts with acids to produce carbon dioxide, reacts with moisture to release ammonia gas
Acute Toxicity: Low toxicity in small exposures, ingestion or inhalation in large amounts may cause irritation or upset stomach
Routes of Exposure: Inhalation, ingestion, skin, eyes
Symptoms: Coughing, shortness of breath, eye redness, stomach upset, nausea
Chronic Effects: Not known to cause chronic illness; long-term repeated contact can cause skin irritation
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
LD50 (Oral, rat): 1,570 mg/kg
Other Data: No evidence of mutagenicity, teratogenicity, or reproductive toxicity in available data for ammonium bicarbonate
Ecotoxicity: Can cause ammonia build-up in soil and water, toxic to aquatic organisms in high concentrations
Persistence and Degradability: Degrades in environment through hydrolysis into ammonia and carbon dioxide, readily biodegradable
Bioaccumulative Potential: No expected potential for bioaccumulation
Mobility in Soil: Soluble, can leach into groundwater
Other Adverse Effects: Large spills may cause eutrophication or harm to aquatic systems
Waste Treatment Methods: Collect and place in suitable container for disposal with licensed chemical waste handler
Disposal of Product: Dispose by landfill or chemical incineration according to local, state, national, and international regulations
