What is the primary purpose of a respirator?

The primary purpose of a respirator is to protect against harmful airborne contaminants. Respirators are specifically designed to filter out hazardous particles, gases, and vapors, thereby safeguarding the respiratory system of workers who may be exposed to these dangers in various environments, including those with asbestos exposure.

While keeping a worker warm, providing oxygen, and improving comfort can be considerations in different contexts or types of equipment, they do not define the main function of a respirator. In the context of asbestos and similar hazardous materials, the focus is squarely on filtration and protection, making the correct choice centered on the critical need for safety against airborne toxins.
