The following is in the National Building Code of Canada;
[/CODE]Here is the question; A deck serving a single dwelling unit has stairs leading to grade. The deck is approximately 10' above grade. Are the guards serving the stairs required to be 36" or 42"?
I proposed that sentence 3 would at the very least require the guards to be 42" where the stair tread was 6' above grade. The other inspector I work with doesn't think stairs constitute a walking surface.
What do you guys and gals think?
Code:
1)Except as provided in Sentences (2) to (4), all guards shall be not less than 1 070 mm high.
2)All guards within dwelling units shall be not less than 900 mm high.
3)Exterior guards serving not more than one dwelling unit shall be no less than 900 mm high where the walking surface served by the guard is not more than 1 800 mm above the finished ground level.
4)Guards for flights of steps, except in required exit stairs, shall be not less than 900 mm high.
