What is a recommended safety precaution when sanding joint compound?

Use gloves while sanding
Wear a dust mask or respirator
Use a vacuum sander
Sand in a well-ventilated area

The correct answer is: Wear a dust mask or respirator

Wearing a dust mask or respirator when sanding joint compound is crucial because it helps protect the respiratory system from fine dust particles that can be harmful if inhaled. Joint compound contains materials such as silica, which, when disturbed, can create airborne dust that poses health risks, including respiratory issues and chronic conditions over time. A dust mask or respirator effectively filters out these particles, significantly reducing inhalation exposure and promoting safer working conditions. While using gloves, utilizing a vacuum sander, and sanding in a well-ventilated area are also important safety measures, they do not address the specific respiratory hazards associated with joint compound dust as directly as using a dust mask or respirator does. Therefore, protecting one's airways is the primary reason this choice is highly emphasized in safety protocols for drywall finishing.
