According to Circular 01/2020/TT-BXD, measures to prevent the spread of fire should be carried out to limit the fire's area, intensity, and duration. Specifically, they are:

- Use structural and layout solutions – spatial arrangement to prevent the spread of dangerous fire factors within a room, between rooms, between groups of rooms with different fire hazards according to their functions, between floors and units, between fire compartments, as well as between buildings.

- Limit the fire hazard and explosion hazard of technology within rooms and buildings.

- Limit the fire hazard of building materials used on the surface layers of building structures, including: roof coverings, facade finishes, rooms, and escape routes.

- Have initial firefighting equipment, including automatic and handheld devices.

- Have fire detection and alarm devices.

Note: Regulations on fire prevention distance between residential, public buildings, and production houses are provided in Appendix E. The distance between flammable liquid warehouses, open-air warehouses containing flammable materials, LPG1) tanks, gas-containing tanks to other buildings must comply with specialized industry standards.

In addition, the standard also specifies that rooms, including those with type 2 staircases, must be separated from the corridors connecting them and other rooms by type 1 fire partitions. It is permitted not to separate rooms with type 2 staircases by fire partitions when: There is automatic firefighting equipment installed throughout the building; or in buildings not exceeding 9 m in height with a single floor area not exceeding 300 m².

Details can be found at Circular 01/2020/TT-BXD, effective from July 1, 2020.
