    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    The Vol. 86, No. 96 Federal Register post also clarifies when a top rail can serve as a handrail (another topic discussed in this thread)! See the following for one snippet on the topic (there are others in the attachment if you want more info): "In light of the employer confusion following...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Hi, All, Take a look at the attachment to this post. Specifically the third column of page 27333. Looks like OSHA did indeed acknowledge the printing error! For posterity, I'll re-write what is in the attachment (in case the attachment ever disappears): Excerpt from Federal Register / Vol...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    JLNJ - to address your issue with a handrail being installed in plane with the stair rail: This is a tricky one, but the below is how I justify that in plane handrails are not allowed (other than the obvious ergonomic issues). It's similar to your sentiment, but with a couple of code /...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Thanks, winelandv! Regarding your "it's been like this for 5 years and hasn't changed so I'll assume that the code as written is what OSHA wants" comment. I'd be careful there -- the "final rules" as we now know them were first written/submitted in 1990 and didn't get final approval until 2017...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Thanks, IFR! That helps clarify situations where the top rail can serve also as a handrail, but I do not believe that clarifies the original question I posed in this thread (which is related to the printing error to table D-2 in the online version of OSHA which muddies the water as to whether...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Thanks for the snippet JLNJ! That jogs a distant memory -- perhaps you can confirm, but is the table you included from the "print" version of the OSHA ruling? I believe I recall that the print version lists that table correctly (but the online version lists it incorrectly).

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Thanks, dauwerda! Regarding the "top rail as a handrail" comment in your earlier response -- my take on that perceived inconsistency is just that OSHA wants to allow grandfathered in stairrail systems (installed prior to Jan 17, 2017) where the top rail is installed between 36 - 38" to also...

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Thanks, winelandv, I submitted the inquiry to OSHA mid October, 2019. I'm still under the working impression that the OSHA response (and the OSHA FAQ) is correct and accurate, but would love for something more official from OSHA on the issue!

    OSHA 29 CFR 1910 Subpart D 1910.28 Section 1910.28(b)(11)(ii) Table D-2 handrail inquiry

    Hello! I understand that Table D-2 (1910.28(b)(11)(ii)) contains a printing error, and that for each flight of stairs with two open sides and a width of less than 44 inches, column 4 of Table D-2 should state "One stair rail system with hand rail on each open side". This was corroborated on the...

    How is frost depth determined / calculated?

    Thanks, all, I am familiar with maps like the one JAE provided, and am familiar with state-amended IBC provisions that speak to frost depth (as well as county, city, town building codes). The question is really how do they come up with these numbers? It sounds like the consensus thus far is...

    How is frost depth determined / calculated?

    Frost depth is an aspect of the majority of foundation design that I do, but thinking about it, I realize I'm not sure how the actual frost depth is determined. I see STP1358, "Remote Field Methods to Measure Frost Depth" (from the ASTM website) outlines several ways that frost depth can be...

    handrail requirements per latest OSHA standard

    Take a look at the following OSHA FAQ: https://www.osha.gov/walking-working-surfaces/faq.html Based on the height requirements for stair rails and handrails and the requirements in Table D-2, are both stair rails and handrails required on stairs that have two open sides and are less than 44-in...

    Garage floor and driveway replacement issues

    Thanks, All, The feedback was very helpful! The contractor has agreed to attempt a fix. They are going to look at potential replacement of the slab, but as OG has indicated they will need to review the feasibility of providing a slope considering the finished walls.

    Garage floor and driveway replacement issues

    Thanks, Ron, Straight for the jugular! To give some context, this wasn't a project that I oversaw - this was a project that members of my family took on (who are not structural engineers). Considering the outcome of their project I offered my advice on how to proceed, and suggested that we post...
