What is the primary purpose of wearing a dust mask during nail treatments?

The primary purpose of wearing a dust mask during nail treatments is to filter harmful dust and chemicals. Nail treatments often involve the use of products such as powders, acrylics, and filing materials that can create fine dust particles. Breathing in these particles can pose health risks, including respiratory problems and skin irritation. A dust mask acts as a barrier, helping to protect the technician from inhaling these potentially harmful substances.

In this context, the other options do not address the key health and safety aspect of wearing a dust mask. Preventing nails from breaking, addressing odors, and enhancing visibility are not the focus of safety measures in nail care practices, making them less relevant to the primary function of a dust mask. Using the mask ensures a safer working environment for the technician, which is critical in maintaining health standards in any beauty-related profession.
