• C. After each day's use or more often if necessary
• D. Before each use only

Answer: (C)

Respirators should be cleaned after each day's use or more often if necessary to ensure their effectiveness in providing respiratory protection. Regular cleaning helps to remove contaminants that can accumulate on the surface of the respirator, which can include dust, moisture, and other particles associated with the user’s activities. This practice not only enhances the hygiene of the device but also extends its lifespan and maintains its seal and function.

Cleaning a respirator after each use is particularly important in environments where pollutants or hazardous materials are present, as failing to maintain cleanliness may lead to health risks for the user. Additionally, if a user experiences excessive exposure to contaminants, a more frequent cleaning routine would be warranted to ensure optimal safety and performance of the respirator.
