Main Health Risks: May cause respiratory irritation, skin irritation, or eye irritation on direct contact; toxic if ingested in large quantities
Routes of Exposure: Inhalation, ingestion, skin, or eye contact
Main Symptoms: Burning sensation in eyes, headache, dizziness, nausea, irregular heart rhythm if consumed
GHS Classification: Acute toxicity, Eye irritation, Specific target organ toxicity
Environmental Risk: Toxic to aquatic life, persistent in water systems
Active Ingredient: Propafenone Hydrochloride
Chemical Family: Class IC antiarrhythmic agent
Purity: Pharmaceutical grade typically exceeds 98%
Additives or Inactive Compounds: Trace residual solvents from synthesis
Inhalation: Move affected person into fresh air promptly; medical attention if dizziness or respiratory symptoms persist
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention for persistent irritation
Eye Contact: Flush eyes gently yet thoroughly for at least 15 minutes using clean water, seek immediate medical care
Ingestion: Rinse mouth, do not induce vomiting; seek prompt medical treatment due to risk of serious toxicity
Physician Notes: Monitor cardiovascular and respiratory status closely; symptomatic treatment often needed
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Hazardous Combustion Products: May release toxic fumes, including nitrogen oxides and hydrochloric acid gas if burned
Protective Equipment: Full protective gear including self-contained breathing apparatus recommended for firefighters
Specific Hazards: Combustion creates ash and smoke, avoid inhalation
Personal Precautions: Wear gloves, goggles, and appropriate protective clothing to limit skin and eye contact
Environmental Precautions: Prevent entry into drains or water systems, avoid spreading dust
Cleanup Procedure: Carefully collect material with minimal dust generation, use damp cloth or mop, transfer to sealed waste container
Disposal: Dispose according to local, state, and federal regulations for pharmaceutical waste
Handling: Work in well-ventilated areas, avoid dust, never eat, drink, or smoke during handling
Safe Storage Conditions: Store in original, tightly closed container; keep away from light, heat, and moisture
Incompatible Materials: Strong oxidizers and acids can react with propafenone hydrochloride
Special Practices: Training recommended for those routinely handling the powder
Control Measures: Use local exhaust ventilation where dust may be generated
Personal Protective Equipment: Nitrile gloves, laboratory safety goggles, long-sleeved coat
Respiratory Protection: Dust mask or NIOSH-approved respirator if significant airborne particles expected

Decomposition Products: Thermal decomposition produces hydrochloric acid and nitrogen oxides
Incompatible Materials: Avoid strong oxidizing agents and strong acids
Polymerization: Not known to occur under normal conditions
Potential Acute Effects: Ingestion may cause cardiovascular disturbances, seizures, or unconsciousness
Chronic Exposure: Data indicates prolonged contact may affect liver or heart function
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA based on available data
Sensitization: Rare but possible with repeated skin exposure
Mutagenicity: Conflicting reports from in-vitro studies; no clear evidence of hazard to humans
Persistence and Degradability: Propafenone hydrochloride tends to remain in aquatic systems, not rapidly biodegradable
Bioaccumulation Potential: Minimal; low potential for building up in food chains
Aquatic Toxicity: Documented toxicity to aquatic organisms at certain concentrations
Hazard to Environment: Recommended to avoid direct release into water bodies
Safe Disposal Methods: Incineration at approved high-temperature facility whenever possible
Container Disposal: Decontaminate and treat as hazardous waste or send for professional disposal
