As stated in The National Building Code – Alberta Edition (NBC(AE)) there are metrics for fire safety in buildings.
To start we should know that is it the building owners responsibility to verify that fire protection and life safety systems and their components (i.e. fire alarm systems, sprinklers, standpipes, smoke control, ventilation, pressurization, door hold-open devices, elevator recalls, smoke and fire shutters and dampers, emergency power, emergency lighting, fire pumps, generators, etc.), including their interconnections with other building systems, are functioning according to the intent of their design. A-3.2.9.1.(1) Testing of Fire Protection and Life Safety Systems.
The “Integrated Systems Testing of Fire Protection and Life Safety Systems,” provides the methodology for verifying and documenting that interconnections between building systems satisfy the intent of their design and that the systems function as intended by the Code.
Here are standards points to ensure the safety of people using the building.
1.Every exit sign- shall consist of a green and white or lightly tinted graphical symbol meeting the colour specifications referred to in ISO 3864-1, “Graphical symbols – Safety colours and safety signs – Part 1: Design principles for safety signs and safety markings,” and conform to ISO 7010, “Graphical symbols – Safety colours and safety signs – Registered safety signs,” for the following symbols (see Note A-3.4.5.1.(2)(c)):
i) E001 emergency exit left, ii) E002 emergency exit right,
iii) E00590-degreedirectionalarrow,and iv) E006 45-degree directional arrow.
2.Internally illuminated exit sign, where illumination of the sign is not powered by an electrical circuit, be constructed in conformance with CAN/ULC-S572, “Photoluminescent and Self-Luminous Exit Signs and Path Marking Systems.”
3.Externally Illuminated Signs. An external lighting source is required to properly charge photoluminescent signs.
floor area, each exit shall be separate from every other exit leading from that floor area.
5. evert exit sign must be illuminated and located above the exit door.
