Whether it is a medical consultation, or a visit to the patient, but any used masks in the medical institution, need to be put directly into the medical waste garbage bags. We have strict procedures for medical waste disposal, and departments need to pre-treat the masks and put them into special containers or bags in separate categories. Waste masks generated from the treatment of pneumonia patients with novel coronavirus infections and suspected patients are collected according to the classification of medical waste. After the masks are collected, they need to be transported to medical waste disposal institutions by special vehicles, and after high-temperature steam, chemical disinfection and microwave disinfection treatment, they will be disposed of in domestic waste landfills or in domestic waste incineration plants.
