Types of Masks

When it comes to plasma cutting, wearing the right type of mask can significantly impact your safety and health. The mask you choose should align with the specific risks you’ll encounter, whether it’s fumes, dust, or radiation. In this section, we discuss the different types of masks you can use: dust masks, respirators, and full-face masks.

Dust Masks

Dust masks, often referred to as surgical masks or disposable masks, provide a basic level of protection from larger airborne particles. While they can help shield against dust and some fumes, they don’t offer sufficient protection against harmful gases or very fine particles. These masks are generally not recommended for plasma cutting, but they are often used for less hazardous tasks like sanding or sweeping. For more information on the limitations and types of dust masks, you can refer to the Wikipedia page on surgical masks.
