What potential health effects can refrigerants have?

Refrigerants can pose various health risks, particularly when they are inhaled improperly. Many refrigerants are classified as toxic substances that can lead to respiratory issues, including irritation of the airways, coughing, or more severe effects in an enclosed space or when exposure levels are high. Additionally, certain refrigerants can have psychoactive effects that may impair judgment or coordination, particularly if there is a high level of exposure. This highlights the importance of proper handling, storage, and ventilation while working with these substances to safeguard health and safety.

The other options suggest a range of effects that do not accurately reflect the potential risks associated with refrigerants, including the idea that they might improve lung function or that they have no health effects, which is misleading given the known hazards. Minor skin irritation is also a concern, but it does not encompass the more significant health impacts associated with inhalation.
