In the refrigerant safety rating B1, what does the number 1 indicate?

• A. High toxicity
• B. Low flammability
• C. High pressure
• D. Moderate toxicity

Answer: (B)

In the refrigerant safety rating system, the letter designation indicates the toxic and flammability characteristics of the refrigerant. The number 1 specifically indicates low flammability, which means that the substance has a relatively low risk of igniting and poses less of a fire hazard under standard conditions. Refrigerants rated with a 1 in the flammability category do not easily catch fire, making them safer to use in various applications compared to those with higher flammability ratings. Understanding these safety ratings is crucial for professionals in HVAC to ensure that they handle refrigerants safely and effectively, thus minimizing risks in both residential and commercial settings.
