What are the correct principles for the location of centralized isolation points?

The principle of centralized isolation point location is as follows:

The Comprehensive Department of the National Bureau of Disease Control and Prevention jointly issued the Guidelines for the Design of Centralized Isolation Points (Trial) (hereinafter referred to as the Guidelines), clarifying that the location of centralized isolation points should be far away from vulnerable groups such as densely populated areas, kindergartens, schools, and care institutions for the elderly.

Centralized isolation points are buildings and supporting facilities for people who require centralized isolation and medical observation for confirmed cases, suspected cases, close contacts of asymptomatic infected people, close contacts of close contacts, entry personnel and high-risk occupational groups in COVID-19.

This guideline is applicable to the design of new centralized isolation point projects, and the design of transforming existing buildings into centralized isolation points can be implemented with reference.

The Guidelines point out that the location of centralized isolation points should meet the requirements of flat terrain, convenient transportation, quiet environment, far away from pollution sources, production and storage areas of flammable and explosive products, and far away from noise, vibration and strong electromagnetic fields.

Reasonable functional zoning should be carried out, including isolated observation area, work service area and health transfer area; There should be no less than two entrances and exits, and separate entrances and exits should be set in the isolated observation area and the work preparation area, and the mutual distance should not be less than10m; Independent sewage outlets should be set up.

The Guidelines require that the green isolation distance between buildings and facilities in the isolation observation area and adjacent buildings outside the campus and buildings in the work service area should not be less than 20 meters. When there is no green condition, the isolation distance should not be less than 30 meters.

Internal roads and greening systems should be rationally planned for centralized isolation points, and the streamline lines for isolating personnel, staff, material distribution and garbage transportation should be clear and convenient to avoid crossing. Outdoor sports venues can be set up if conditions permit.

The isolated observation unit shall be a single isolated observation room, and the use area of each single isolated observation room shall not be less than 14 square meter. A certain proportion of multi-person isolation observation rooms and barrier-free isolation observation rooms should be set up to meet the needs of special groups such as minors and the elderly.

Requirements for staff in the guidelines

When entering the isolated observation area, the staff should go through rooms such as changing clothes, wearing protective equipment and buffering. When returning to the work service area from the isolated observation area, you should go through rooms such as one take-off, two take-off, shower (which can be set as needed) and change clothes; The ventilation system of isolated observation area, work service area and health transfer area should be set independently in each area.

At the same time, a video security monitoring system is set up at the centralized isolation point, and monitoring cameras are set up at important positions such as the entrance and exit of the isolation point, the isolation observation area, the isolation observation unit, the sanitary passage area, and the garbage temporary storage room. Two-way voice intercom camera should be used in the health transfer area to facilitate the remote supervision and guidance of relevant personnel on duty or in the nursing station.
