Question: 1 / 400

Are refrigerants generally lighter or heavier than air?

Lighter

Heavier

Refrigerants are generally heavier than air. This characteristic is important in understanding how refrigerants behave in the environment. When released, heavier-than-air refrigerants tend to stay closer to the ground instead of dispersing quickly into the atmosphere as lighter gases would.

This behavior has implications for safety and environmental considerations. For instance, if a heavier refrigerant leaks in an enclosed space, it may accumulate at lower levels, posing a risk to individuals who are in that space. In contrast, lighter gases would rise and potentially disperse more quickly into the atmosphere, which may reduce the immediate danger.

Understanding these properties helps technicians and environmental professionals manage refrigerants safely and in compliance with regulations, such as those set by the Environmental Protection Agency (EPA).
