safety precautions for propionic acid (CAS 79-09-4)
Storage Guidelines
- Container Material: Store propionic acid in plastic (HDPE) or stainless steel containers to prevent corrosion.
- Temperature Control: Keep away from heat sources and direct sunlight to reduce fire risk.
- Segregation: Avoid storing near oxidizers, strong acids, and bases.
- Ventilation: Ensure storage areas are well-ventilated to prevent vapor accumulation.
Handling Precautions
- Operate in well-ventilated areas to minimize vapor exposure.

Fire and Explosion Safety
- Flammability: Propionic acid has a flash point of ~54°C and may ignite near open flames or sparks.
- Fire Extinguishing: Suitable extinguishing media include foam, dry chemical, or CO₂. Avoid using water streams directly on concentrated liquid spills.
- Emergency Response: In case of fire, evacuate personnel and ventilate the area after extinguishing.
