2.3.1 Construction
components shall be characterized by fire resistance and fire risk.
Fire resistance of a
component is represented by the fire-resistance rating of that component. Fire
risk of a component is represented by fire hazard level of the component.
2.3.2 Fire-resistance
ratings of construction components are determined by a period of time (in
minutes) from the point in which fire resistance tests with standard heat begin
until one or many following signs of limit states prescribed for the components
as per the law appear:
- Loss
of load-bearing capacity (load-bearing capacity is assigned with the letter
“R”).
- Loss
of integrity (integrity is assigned with the letter “E”).
- Loss
of thermal insulation (thermal insulation is assigned with the letter “I”).
NOTE 1: Fire-resistance
ratings of construction materials shall be determined by fire resistance test
according to standards from TCVN 9311-1:2012 to TCVN 9311-8:2012 or equivalent
standards. Fire-resistance rating of construction materials can be identified
by calculation according to applicable fire-resistance design standards.
Fire-resistance ratings of
air ducts shall conform to ISO 6944 or equivalent standards.
Fire resistance rating of
fire suppression valves of ventilation systems shall conform to ISO 10294.

NOTE 2: Required
fire-resistance ratings of specific construction components are mentioned in
these Regulations and technical regulations applied to each type of
construction. Fire-resistance ratings of construction components are
represented with REI, EI, RE or R accompanied by number dictating duration of
burning in minute. E.g. A component with fire-resistance rating of REI 120
means the component must be able to retain all 3 capacities: load-bearing,
integrity and thermal insulation under impact of fire for 120 minutes; a
component with fire-resistance rating of R 60 means the component must be able
to retain load-bearing capacity for 60 minutes regardless of integrity and
thermal insulation.
NOTE 3: Some construction
components are considered as satisfactory to fire resistance (fire-resistance
ratings) if any of following conditions is satisfied:
a) The components share
technical properties with samples of fire resistance test and samples display
fire-resistance ratings no lower than the required fire-resistance ratings of
those components.
b) The components share
technical properties with components specified in Annex F and corresponding
fire-resistance rating under Annex F is no lower than required fire-resistance
ratings of said components.
c) Fire-resistance rating of
components determined by calculation according to standard fire resistance
design must be no lower than required fire-resistance ratings of said
components.
2.3.3 With
respect to fire risks, construction components shall be classified into 4
categories:
- K0
(no fire risk).
- K1
(mild fire risk).
- K2
(moderate fire risk).

3.1.2 Evacuation
refers to organized movement of humans from rooms where dangerous elements of
the fire may affect them to outside. Evacuation also refers to involuntary
movement of people having limited movement capabilities with assistance of
servers. Evacuation is done via evacuation exits.
3.1.3 Rescue
refers to forced movement of people towards the outside who are under influence
of dangerous elements of the fire or in case of direct presence of said
influences. Rescue shall be performed voluntarily with assistance of fire brigade
or professionally trained employees, including use of rescue equipment via evacuation
exits and emergency exits.
3.1.4 Protection
of humans on evacuation route must be guaranteed by clearance – space
organization solutions, conveniences, structures and technical properties of
buildings and organizations.
Evacuation routes within the
rooms must guarantee safe movement towards evacuation exits from said rooms
without taking into account smoke protection and fire suppression in the rooms.
Outside of the rooms, must
protect evacuation routes taking into account of fire hazard categories of
rooms above the evacuation routes, number of people evacuating; fire-resistance
categories and structural fire hazard levels of buildings, number of evacuation
exits on one storey and from the entire buildings.
Construction material fire
hazard levels of rooms and evacuation routes outside of rooms must be limited
on surface levels (finishing layers and cladding) depending on fire hazard
categories of the rooms and buildings, taking into account other solutions
regarding protecting evacuation routes.
3.1.5 When
designing evacuation from rooms and buildings, do not take into account of
rescue measures and devices and exits that fail to satisfy exit requirements
under 3.2.1.

3.2.8 In
case of at least 2 evacuation exits, situate said exits separately and take
into account chances of the fire preventing people from using any of the exits
when calculating evacuation possibilities. Remaining exits must be able to
ensure safe evacuation for all people in the rooms, on the storeys or in the
buildings (illustration in Figure I.3).
If a room, section or storey
of a building requires at least 2 evacuation exits, at least 2 of said exits
must be separated from another and the distance between any 2 exits must equal
or larger than half of the longest diagonal line across the room, section or storey
of the building. Distance between 2 evacuation exits shall be measured by the
straight lines connecting their 2 nearest sides (illustration in Figure I.4 a),
b) and c)).
If buildings are totally
protected by sprinkler fire suppression systems, the distance may be reduced to
1/3 of the longest diagonal line of spaces mentioned above (illustration in
Figure I.4 d)).
If 2 evacuation stairwells
are connected by a corridor, the distance between 2 evacuation exits (2 doors
leading to the evacuation stairwells) shall be measured along the corridor
(Figure I.5). The corridor must be protected according to 3.3.5.
3.2.9 Clearance
height of emergency exits must not be less than 1.9 m, clearance width must not
be less than:
