What should be ensured to enhance safety while handling refrigerants?

Ensuring proper ventilation is essential while handling refrigerants because many refrigerants can be hazardous, posing risks such as asphyxiation or exposure to toxic substances. Adequate ventilation helps disperse any refrigerant leaks, reducing the concentration of harmful gases in the air and minimizing the risk of adverse health effects on those working in the vicinity. This is particularly crucial in enclosed spaces where refrigerants could accumulate.

In contrast, low-quality equipment, minimal training, and the use of old and outdated tools can all lead to increased safety risks. Poor equipment may fail or leak, insufficient training can lead to improper handling of refrigerants, and outdated tools might not meet current safety standards. Therefore, ensuring proper ventilation is a critical safety measure when working with refrigerants.
