The correct answer is: To prevent reuse and cross-contamination

Storing or disposing of used masks properly is critical primarily to prevent reuse and cross-contamination. Masks, especially those designed for protection during a pandemic or from hazardous materials, can become contaminated with pathogens, droplets, or other harmful substances when worn. If these masks are not handled appropriately after use, there is a risk that they could be inadvertently reused, which could facilitate the transmission of infections or exposure to hazardous materials. Proper disposal methods, such as placing used masks in designated waste containers, ensure that they are not accessible for unintended use or mishandling. This is especially important in environments such as healthcare facilities or laboratories, where the risk of infection or contamination is high. By following proper protocols for disposal, the potential for spreading contaminants is significantly reduced, highlighting the importance of maintaining hygiene and safety standards.
