What type of gas are R-12 and R-22 classified as?

R-12 and R-22 are classified as nonflammable compressed gases. This classification is important because it reflects their properties in terms of flammability and safety handling. Both of these refrigerants are halocarbon compounds used primarily in cooling applications like air conditioning and refrigeration.

Being nonflammable means that these substances do not easily ignite in air under standard conditions, making them safer to use in environments where the risk of fire is a concern. This is a significant distinction from flammable gases, which can pose a serious risk due to their potential to catch fire and explode.

Understanding the classification of refrigerants is crucial for technicians working with these substances, as it influences how systems are maintained and the safety precautions needed when handling refrigerants. Additionally, while R-12 and R-22 can have health implications and should be handled with care, they do not fall into the categories of highly toxic gases or inhalation hazards under normal conditions when proper safety measures are followed.
