2. Application:
Pentafluoroethane is primarily used as a refrigerant in air conditioning systems, industrial and commercial refrigeration and chillers.
It is also a key component in the preparation of refrigerant blends such as R404A, R407C, R410A, and R507, which are replacements for R22 and R12. Additionally, it can be used as a fire extinguishing agent to replace certain halon-based fire extinguishing systems.

3. Storage:
Store in a dry, well-ventilated area away from heat sources.

4. Handling:
Treat all chemicals as hazardous.
Avoid direct physical contact.
Use approved safety equipment.
Untrained individuals should not handle this chemical or its container.
Handling should take place in a chemical fume hood.

5. Special Hazards:
Thermal Decomposition: Produces toxic and harmful substances.
Liquid Gas Leakage: Rapid vaporization can absorb heat, potentially causing skin injuries.
Enclosed Space Leakage: May cause suffocation; proper ventilation is essential.
High Concentration Inhalation: Can lead to dizziness, headache, confusion, movement disorders, and even cardiac arrest in severe cases.

6. Firefighting Measures:
Use fire extinguishing agents suitable for surrounding fires.
Cool affected containers with large amounts of water from a safe distance.
Do not use water directly on the material.
Use water spray to knock down vapors.
