Which type of refrigerants generally requires more stringent handling procedures?

Synthetic refrigerants with high global warming potential are associated with greater environmental impacts and regulatory measures due to their contribution to climate change. These substances can cause significant harm to the atmosphere if released, leading to stringent handling procedures to prevent leaks and ensure proper management during maintenance and disposal.

The handling of these refrigerants often requires specialized training, personal protective equipment, and adherence to environmental regulations to minimize risks. Furthermore, these refrigerants might necessitate specific recovery and recycling processes to mitigate their potential detrimental effects on the environment.

In contrast, the other types of refrigerants cited may have less stringent handling requirements due to their lower environmental impact or toxicity levels. Non-toxic refrigerants typically do not pose significant health risks, natural refrigerants often have a lower global warming potential, and water-based refrigerants are not harmful at all, making their handling less critical in comparison to those with high global warming potential.
