stair nosings

[syarn]

in the attached picture in a museum the patrons (mostly children & parents) are reportedly falling off the steps often enough to prompt the museum to consider a type of remedy.there is a ramp nearby for an alternate way to get up to the higher floor level.if the museum was considering installing "studs" or "truncated domes" if you will along the edge near the stair nosings to create some contrast does this alteration have to comply with accessibility codes ansi-a117.1-2009 e.g. section 504.5 on nosings or 705.5 on truncated domes?

Perhaps some stripping for the visually impaired would be in order. handrails?

Striping and handrails would help.....I wouldn't think that adding a contrast strip would drive any other upgrades or compliance.....Not sure exactly what you are looking for....

Installl a contrasting color carpet across the entire middle step. I believe that if you stand back a little further or are short like a child it is hard to "notice" the steps.

Coming down would be the real hazard....wouldn't see the risers at all.....

Also, doesn't the tred depth vs height exceed minimums?

Handrails required?

 

[fatboy]

Yes, they exceed minimums, so it is code compliant. Extra wide treads with a low rise isn't such a good design idea though. Folks are used to the 7"/11" motion.

 

[ADAguy]

That is a "truism"

Interior design vs. common sense again.

As mentioned earlier contrasting color carpeting could certainly help but even doing it just to the middle step might not be sufficient. I think that a strip of contrasting color at the front of the top step would be seeing much farther away of the steps for patrons walking towards them. Of course I also agree with the others who have referenced the normal step rise and run versus what they are in this case. Obviously changing the step sizing would be extremely beneficial but much more expensive than just installing contrasting carpet colors. I think the idea of truncated domes or something like that could almost cause more of a problem by increasing the potential for tripping when patrons are used to walking on a very smooth softer surface.

thank you to all

1009.7.2 Riser height and tread depth.

Stair riser heights shall be 7 inches (178 mm) maximum and 4 inches (102 mm) minimum.

Can't tell from the picture if they have the minimum rise permitted.
