- The bottom of the low-level sign must be installed at a distance of 150 mm to 200 mm from the floor. The distance between signs must be placed no more than 10 m apart. For emergency exit doors, the sign must be on the door or adjacent to the door with the nearest edge of the sign within 100 mm from the door frame (see figure A.5).
- Low-level safety signs are designed to assist people living and working in the building to the exits when smoke obscures the exits or signs indicating the exits are mounted at above the door and does not replace the standard safety sign.
Standards for design and installation of emergency exit diagrams in fire prevention and fighting?
Pursuant to subsection 5.2, Section 5 of the National Standard TCVN 13456: 2022 stipulating standards for the design and installation of an escape instruction diagram in fire prevention and fighting work as follows:
-At floors with an area larger than 1000 m2 or with two or more emergency exits, there must be an emergency exit diagram (see Figure A.6).
- In the rooms of hotels and accommodation establishments, rooms for rent must have an escape plan (see Figure A.7).
- The emergency exit diagram consists of two parts: the instructions in words and the part with geometric symbols. The emergency exit diagram must be posted at recognizable, conspicuous positions and frequented by people (see figure A.6).
+ The part of geometric symbols includes the floor plan; exits and direction of escape routes; stairs; the location of the plan at the floor; location of means and equipment for fire fighting and rescue and rescue (symbols in accordance with the provisions of TCVN 4879:1989 and TCVN 5053: 1990).
