[RE-wrenches] Fall Protection Equipment

Mon Jan 19 08:04:08 PST 2015

William,

As Dan mentioned there are harnesses with both front and rear D-rings.  For the application you describe I would recommend using a tower harness that includes a saddle with waist strap D-rings.  I personally prefer the Guardian Tower Edge harness.  It is perfectly acceptable to use the front D-ring only as long as you are using it in “restraint”, where your positioning device is located so there is not enough slack in the rope to let you fall over the edge.  If there is a possibility you might actually fall off the roof then the rear ring must be used.

Cheers,

Garrison

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".

Aloha my Wrench Brothers!
We have a recent defector from a very large National Solar company here that brought in this great Fall gear (see attachment). To be honest it blew my mind how simple and light it was....Is anybody else using this rock climbing equipment as fall protection gear? Is this approved by OSHA.

You would figure if humans just free climbed El Capitain with gear like this it would do just fine keeping me safe and compliant at 6 feet and above.

The rope grab is made by KONG. 

Mahalo in advance!
