Bian Zuodong, deputy director of the Market Supervision Department of the State Post Office, explained that according to the changes in the tasks of the current epidemic prevention and control situation in China, the State Post Office has issued a notice making specific arrangements for implementing the “Class B and B Control” overall plan for COVID-19 infection, preventing and controlling the epidemic in the postal express delivery industry, clarifying work requirements, and proposing optimization and improvement measures. Among them, enterprises are required to strengthen the daily public health management of distribution centers and business outlets, and regularly clean, disinfect, and ventilate the environment. In order to cope with the situation where workers are unable to take up their jobs due to infection, enterprises should establish and improve rotation and preparation mechanisms for key positions, strengthen the deployment of workers and the provision of epidemic prevention materials, and arrange for the entry and rotation of reserve teams according to the rotation preparation mechanism when personnel are reduced, so as to minimize the impact of the epidemic on the normal operation of the industry.
