What are the regulations on equipment and installation of fire extinguishers for houses and buildings in Vietnam?
In subsection 5.1, Section 5 of National standard TCVN 3890:2023 on Fire protection - Fire protection equipment for building and construction - Equipment, Installation in Vietnam, the regulations on equipment and installation of fire extinguishers for houses and buildings in Vietnam are as follows:
- Equipment and installation of portable and wheeled fire extinguishers.
+ All areas in buildings and constructions, including areas equipped with fire extinguishing systems, must be equipped with portable or wheeled fire extinguishers.
+ The selection, equipment and installation of fire extinguishers shall comply with the regulations laid down in Articles 6 and 7 of TCVN 7435-1.
+ For narrow and long areas or areas with different and adjacent floor levels, a fire extinguisher must be installed so that the travel distance from the position of a fire extinguisher to the farthest point to be protected does not exceed that specified in 5.1.1.2.
+ On the same floor or storey, if the premises is separated into different areas by walls, partitions or other obstacles without any passageway, fire extinguishers must be installed separately in accordance with 5.1.1.2 and 5.1.1.3.
+ The number of fire extinguishers reserved must not be less than 10% of the total number of fire extinguishers intended for replacement where necessary (no more than 100 of each type).
+ Fire extinguishers must be placed in conspicuous and easily accessible locations and should be red. If it is difficult to identify them, signs that show their locations may be used and the regulations set out Article 5 of TCVN 7435-1 shall be complied with. Fire extinguishers must not be placed in a single location, except for the case where they are placed in a storage area in accordance with 5.1.1.5.

+ Hanging type automatic diffusion dry-powder fire extinguishers may be installed in kitchen areas of restaurants, boiler rooms and laundry areas with an area not exceeding 100 m2. If installed in an area of more than 100 m2, it is recommended that such area be divided into areas by a fire-separating wall (with a fire-resistance rating at least REI 45) or a fire separating partition (with a fire-resistance rating at least EI 45), each of which must not exceed 100 m2.
