Handrail wall Encasement

[tbz]

Good morning All,

1st: Does this comply in your view within the IBC?

2nd: What dimension do you hold to allow handrail access?

Picture below - figure it meets the 20% of A117.1 & ADA for 505 20% requirement.

What is the dimension between the top of the gripping surface and the overhang. I don’t care for the sharp corner on the overhang.

 

[ICE]

1014.7 Clearance. Clear space between a handrail and a wall or other surface shall be not less than 1-1/2 inches. A handrail and a wall or other surface adjacent to the handrail shall be free of any sharp or abrasive elements.

An argument could be made that set in the wall is not 1-1/2 inches away from the wall. A person that's lost their balance and tries to catch themselves with the handrail might not be able to do that with the configuration as shown. Perhaps the 1-1/2 inches is only for finger clearance and that makes sense too

Agree with the "sharpness" issue , and 1.5" is all I could enforce for clearance.....

This brings up an interesting point. Handrails do not have a clearance requirement for above, but grab bars do (ICC/ANSI A117.1- section 609.3)

 

[steveray]

Also nothing for how far "away" from the walking surface they can be....

Exactly, I am submitting a code change proposal to address that. Have an example of a handrail set back 4" from the edge of the stringer.

 

[steveray]

I have "had" people do similar when the built guard is too low, put the HR on top to act as the guard...I am sure there are some ergonomic studies to say how far out is too far, but I haven't run into anything I am uncomfortable with yet...

CANNOT FIND ANYTHING IN 2010 ADASAD TO PREVENT IT


THIS IS IN THE CA CODE, FOR RESIDENTAL ACCESSIBILITY



THIS USED TO BE IN THE CODE FOR ALL ACCESSIBILITY

Great Question and replies!!

I love it when someone asks a code question and it reveals another code that has changed and I wasn't aware of the change or deletion. Maybe the code change wasn't brought up in a code change class, or for other organic reasons I've forgotten? Mark's answer and graphics got me to looking back at my old ADA Code reference materials. Thank you!

The language for recessed handrails appears to still be applicable per ADAAG and the Federal Standards.

Love it when you get all types of responses.

Thanks everyone, helps a lot...
