Content regarding resolving difficulties in fire safety and firefighting operations in Vietnam

According to Official Dispatch 1091/C07-P3,P4,P7, the content regarding resolving difficulties in fire safety and firefighting operations includes a number of notable points as follows:

- Regarding fire-stop solutions

With respect to constructions according to the 3.4.16 of the QCVN 06:2022/BXD that have situated sufficient number of exit staircases, it is permissible to situate type 2 staircases for non-exit purposes to lead from first-storey lobby to upper storeys when requirements below are met:

+ First-storey lobby is physically separated from adjacent corridors and rooms by type 1 fire-resistance-rated partitions; upper lobbies do not contain flammable substances.

+ In upper storeys, type 2 staircases must be physically separated by type 1 fire-resistance-rated partitions or corridor enclosing structures connecting to type 2 staircases are type 1 fire-resistance-rated partitions.

- Regarding exit solutions

Enclosing structures of means of egress of single-loaded corridors are not required to have sufficient fire-resistance rating and door closers for doors that open to these corridors in accordance with Article 3.3.5, 3.2.11 of QCVN 06:2022/BXD; single-loaded corridors longer than 60 m are not required to be physically separated by type 2 fire-resistance-rated corridors.

-  Regarding provision of firefighting apparatus

The TCVN 3890:2023 has removed certain provisions compared to the 3890:2009 such as

+ Lowering conditions for water supply for outdoor firefighting;

+ no longer requiring fire alarm and detection, automatic extinguishing system for rooms with fire class D and E;

+ Increasing the area requirement for automatic extinguishing system in production rooms with fire risk class C to 1.000 m2.

+ With respect to rooms manufacturing facilities and storage facilities that have been equipped with automatic extinguishing system connected to fire control units, automatic fire detectors are not required.

Therefore, it is permissible to apply the TCVN 3890:2023 in order to reduce equipment load for project developers.
