Which refrigerant classification refers to a refrigerant that has low flammability?

• A. High Flammability
• B. Not Flammable
• C. Low Flammability
• D. Moderate Flammability

Answer: (C)

Flammability classifications for refrigerants indicate how easily a substance can ignite and burn. A refrigerant with low flammability has only a small chance of catching fire and sustaining combustion; it’s safer than those labeled highly or moderately flammable, but not completely nonflammable. Not flammable would imply no ignition risk under standard conditions, which is a stricter claim than low flammability. Therefore, describing a refrigerant as having low flammability is the correct way to convey its relatively small fire risk.
