Guardrails and "walking surface"

[Bentley]

Andrew,

This is a really interesting topic (more frustrating for you I am sure). My first question to the commissioner would be, is it reasonable for pedestrians to use the top of the wall as a path? “Walking surface” is usually used in conjunction with a required egress point or to talk about a accessible path. Now, if any retaining wall is taller than 4 feet the OSHA rules kick in and you’d need the 42″ ht fall protection fence. Has this been built yet?

Since there is no definition of “walking surface” this Building Commissioner is defining it as “anything that you can walk on”, so we are going to add planters in front of the wall to reduce the drop to <30″ where we can and add railings where we can’t. Fortunately the homeowner is fine with dealing with it. …. I’m just not sure about the other job with a similar situation across town is going to go – totally a different homeowner personality.

Three other building commissioners in different towns did accept a planting bed as creating the 36″ separation of walking surface and did not require the railing.

The high side of the wall is no longer a workplace, so OSHA is not an issue at this time. Also it is a 6′ drop in a construction zone rather than 4′ in an industrial work space. However, I am having a hard time finding a horizontal distance to when that applies to people not using construction machinery (6′ parallel, 10′ perp.).

That seems crazy for him to be able to apply the code that way. Maybe as you begin to establish a working relationship with him you can convince him otherwise?

As far as OSHA is concerned, you are correct that it’s a 6′ drop for construction but it’s 4′ drop for general industry. Unless I am misunderstanding what you mean by “industrial work space”, general industry covers a wide range of activities but doesn’t include construction, maritime, and some others. I always have a fall protection fence for ret. walls at the 4′ level in anticipation of landscape maintenance activities. Obviously, I could be wrong.

I’m not sure about that either when applied to landscape maintenance. I think there are some loopholes where other restraints are accepted, but you and I know that residential landscape maintenance companies think OSHA is an island in the Pacific. It will only be a 29″ drop on this job anyway. Thanks for engaging in the discussion.

Haha, that’s very true. I hope you are able to wrangle the new building commissioner.
