[RE-wrenches] Perimeter warning lines

[R Ray Walters]

As I understand it, OSHA regs don't require you to purchase a certain product. We built our own bases (2x4s, and saw horses, etc) and weighted them with extra ballast blocks from the PV ballasting. We also used a regular rope with the required strength, and hung warning flagging along with it.
The problem I see with your install, is that I believe the warning line needs to be 6 ft from the edge, so you'll have to rope in etc, to do that first row, and then put up the warning line (on top of the first row?)
We never had an OSHA inspection, so I can't say for sure that our method is 100% compliant, but it met all the requirements as I interpreted them.
This may be like an inspection issue: call and ask the local OSHA office having jurisdiction before, to make sure you have what they want to see.
Pretty funny, cause I see roofers just running all over the place with no safety stuff at all. They reroofed my house: a 25 ft fall off a 8:12 pitch, and the guys were right at the edge sitting on a foam pad, with NO ROPE!

Because of skylights down the middle of the length of the E-W roof we are forced to mount the southern-most row only about 5 feet from the 20 foot high eave. Fortunately the slope is less than 10 degrees but perimeter warning lines are a must here.
> Not wanting to appear a cheapskate here but I'm not surprised at the outrageous cost of "OSHA compliant" perimeter warning flag systems. Your basic fold up standards with nothing more than light-weight bases and multi-colored banner rope runs hundreds of dollars. Even sandbags for ballast are way overpriced.
