What type of personal protective equipment (PPE) is typically used when working with refrigerants?

When working with refrigerants, it is critical to use appropriate personal protective equipment (PPE) to ensure safety and minimize exposure to potentially harmful substances. The correct answer emphasizes a combination of gloves, goggles, and respiratory protection.

Gloves protect the skin from direct contact with refrigerants, which can cause frostbite or chemical burns. Goggles are essential because they safeguard the eyes from refrigerants that may enter the air or spill during handling, which is crucial since exposure could lead to severe eye irritation or damage. Respiratory protection is also important in scenarios where there might be a risk of inhaling refrigerant vapors, as these can be hazardous when concentrated in the air.

In contrast, relying on only gloves does not provide sufficient protection given the potential risks from exposure to refrigerants. Standard work boots, while useful for general industrial safety, do not address the specific dangers of chemical exposure. The notion that no PPE is required is not aligned with safety protocols, as handling refrigerants poses various health risks without adequate protective measures. Therefore, using a comprehensive set of PPE, as indicated in the correct answer, is vital for safe practice in environments involving refrigerant use.
