<br>
What's your opinion on Petzl's professional line of full body
harnesses? I noticed too that their cool strapped helmets are
ANSI approved. I never thought regular strapless construction
hard hats made sense on a roof either. (always falling off and
causing a hazard to workers below.....)<br>

OSHA personal safety harnesses are designed to keep someone
upright and without pressure on the diaphragm in the event of
loss of consciousness.<br>
Having done substantial rock and ice climbing with state of
the art climbing gear, I can tell you that it is not designed
for that at all.<br>

<div>Industrial fall protection with rear attachment offers no
functionality in keeping a worker in place on a steep steel
roof. We install planks in these situations but would also like
to be able to cinch up a line connected to the workers waist or
chest in the front to provide extra stability. Rear attached
harnesses do not provide that. </div>

<div class="moz-cite-prefix">I prefer climbing gear as its
much lighter weight and doesn't drag you around. I actually
think in some cases that traditional fall protection gear
can be more of a tripping hazard than the safety it
provides. However, I was previously under the impression
that if OSHA (or in the islands: HIOSH) came around, we had
to ditch the climbing gear and get into the 3 times as heavy
regular harnesses.<br>
I just looked at the OSHA website though, and it doesn't
seem to specify certification, just that the equipment meet
the fall criteria as Dan mentioned.<br>

This doesn't mention test procedures or certification of
equipment. Here's more from the actual OSHA 1926 book:<br>
<br>
<span class="blackTen"><strong><font class="standard">1926.502(e)(3)</font></strong>
<blockquote>Connectors shall be drop forged, pressed or
formed steel, or made of equivalent materials.</blockquote>
<a moz-do-not-send="true" name="1926.502(e)(4)"></a> <strong><font
class="standard">1926.502(e)(4)</font></strong>
<blockquote>Connectors shall have a corrosion-resistant
finish, and all surfaces and edges shall be smooth to
prevent damage to interfacing parts of this system.</blockquote>
<a moz-do-not-send="true" name="1926.502(e)(5)"></a> <strong><font
class="standard">1926.502(e)(5)</font></strong>
<blockquote>Connecting assemblies shall have a minimum
tensile strength of 5,000 pounds (22.2 kN)</blockquote>
<a moz-do-not-send="true" name="1926.502(e)(6)"></a> <strong><font
class="standard">1926.502(e)(6)</font></strong>
<blockquote>Dee-rings and snaphooks shall be proof-tested
to a minimum tensile load of 3,600 pounds (16 kN)
without cracking, breaking, or taking permanent
deformation.<br>
<br>
</blockquote>
</span>"Equivalent materials" ? Seems that an aluminum
caribiner that meets the other criteria would be equivalent.<br>
<br>
Here, Petzl also makes a full line of worker safety
equipment: <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.petzl.com/en/Professional/Verticality?l=US#.VLqw4nuLXfc">http://www.petzl.com/en/Professional/Verticality?l=US#.VLqw4nuLXfc</a><br>
<br>
This is really interesting, and I would like to have a more
definitive answer from OSHA. It would be great if we could
use lighter weight climbing gear; just compare a caribiner
to the heavy steel monsters you get at Grainger's. As long
as it is strong enough:<br>
Lighter weight = less fatigue= safer, IMHO. <br>
As with so many discussions on this list, it will ultimately
depend on your local authorities.<br>

<pre wrap="">James,
This looks like a pretty nice lanyard w/ shock-absorber, rope-grab and rope.
What type/style harness did he bring along?
Re: OSHA approved...great question. Prior to looking into it further I'd suspect it falls in a "grey area".
