Hi Glenn;
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.....)

Standard OSHA personal safety harnesses are designed to keep someone
upright and without pressure on the diaphragm in the event of loss of
consciousness.
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.
Sincerely,

Subject: Re: [RE-wrenches] Fall Protection Equipment
Friends:
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.

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.
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.
https://www.osha.gov/Region7/fallprotection/fall_protection_info.html
This doesn't mention test procedures or certification of equipment.
Here's more from the actual OSHA 1926 book:
*1926.502(e)(3)*
Connectors shall be drop forged, pressed or formed steel, or made
of equivalent materials.
*1926.502(e)(4)*
Connectors shall have a corrosion-resistant finish, and all
surfaces and edges shall be smooth to prevent damage to
interfacing parts of this system.
*1926.502(e)(5)*
Connecting assemblies shall have a minimum tensile strength of
5,000 pounds (22.2 kN)
*1926.502(e)(6)*
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.
"Equivalent materials" ? Seems that an aluminum caribiner that meets
the other criteria would be equivalent.
Here, Petzl also makes a full line of worker safety equipment:
http://www.petzl.com/en/Professional/Verticality?l=US#.VLqw4nuLXfc
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:
Lighter weight = less fatigue= safer, IMHO.
As with so many discussions on this list, it will ultimately depend
on your local authorities.

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".
