What is the LFL of R-32?

• A. 12.4%
• B. 14.4%
• C. 16.8%
• D. 18.0%

Answer: (B)

The Lower Flammability Limit (LFL) of R-32 is 14.4%. This value indicates the minimum concentration of R-32 in air needed for the refrigerant to ignite and sustain a flame when combined with oxygen. Understanding the LFL is critical for safety in handling and using this refrigerant, as it helps technicians determine safe operating conditions and the necessary precautions to avoid potential fire hazards. In comparison to the other options, knowing the accurate LFL value is essential for risk assessment and ensuring compliance with safety standards in refrigerant handling. Understanding these thresholds aids in creating an environment that minimizes fire risks, particularly in systems where R-32 might be used.
