There is spam in this page, such as the reference to a company easy access ramps in the text of the page, that is not being cleaned up — Preceding unsigned comment added by 80.218.228.223 (talk • contribs) 10:34, 4 March 2007
The information in this article is incorrect. At no time does ADA recommend a slope of 2:12. (9.5 degrees of incline). Most Power Wheelchairs can NOT even handle that slope. This mis-information has put people in danger!!!! — Preceding unsigned comment added by 70.46.6.138 (talk • contribs) 15:14, 6 June 2007
The posts above are unsigned. This begins a new post (October 20, 2008)
I agree with the second comment above; there are several serious errors in this article.
First, the Americans With Disabilities Act (ADA) and the ADA Architectural Guidelines (ADAAG) do not apply to residential homes, only to public buildings.
Second, ADAAG does not allow ramps steeper than 1 inch rise to 12 inches run. Additionally ADAAG recommends making ramps as shallow as conditions permit, as shallow as 1 to 15 or 20, if possible.
Third, I am an ADA inspector and plan reviewer in the USA and have never found any accessibility code allowing steep 2:12 or 3:12 ramps for empty wheelchairs or for any other reason.
There are many other useful rules regarding wheelchair ramps that should be included here. Guidelines about handrails, overall length of ramps, sizes of landings, edge protection -- all these affect safety and usability.
The use of the word "cement" instead of "concrete" is incorrect. Other errors in usage and grammar also should be corrected and the overall sentence and paragraph styling should be edited, IMHO.
This is my first comment to Wikipedia. I am willing to rewrite this article but do not want to overstep. Any comments? Fizmijit (talk) 03:13, 21 October 2008 (UTC)[reply]
This is a TERRIBLY written article. It gives misinformation and includes bad references. I will try to post an alternative article in the next few days. My problem is that I am not qualified as a wiki writer and may make some coding errors. Question: Should I post my revised article here in the discussion section or should I post it directly on the article page? — Preceding unsigned comment added by 78.56.26.173 (talk • contribs) 09:06, 7 March 2010
I removed the incorrect ADA slope guidelines and replaced them with the correct ones. I also noted that the ADA does not apply to residential construction. I will try to keep working on this article as I am able to research it. Jeremy Sheffel (talk) 13:16, 10 September 2010 (UTC)[reply]
Wheelchair ramps are covered by BS 8300:2009+A1:2010 (http://www.ihsti.com/tempimg/2A83A2D-CIS888614800295005.pdf), which gives a table for permissible ramps thus:
Table 1 Limits for ramp gradients Going of a flight/Maximum gradient/Maximum rise
10m 1:20 500mm
9m 1:19 473mm
8m 1:18 444mm
7m 1:17 411mm
6m 1:16 375mm
5m 1:15 333mm
4m 1:14 285mm
3m 1:13 230mm
Not exceeding 2 m 1:12 166 mm No individual flight of a ramp should have a going of more than 10 m or a rise of more than 500 mm. If a series of ramp flights rises more than 2 m, an alternative means of step-free access, such as an enclosed lift, protected from the weather, should be provided. The cross-fall gradient of a ramp should be not more than 1:50.
I hope this may be of help to anyone interested on working on this page Yevad (talk) 11:24, 19 November 2013 (UTC)[reply]
