tower

The raw video is of an actual tower  rescue in Washington DC. No, not a telecom climber stranded high up an antenna, but a worker dangling on his safety line after his motorized scaffolding had a catastrophic failure. It was Tower 3 who positioned themselves to be able to use the bucket to go get the worker and unclip him from his system and eliminate the need for any type of rope rescue (damn).

A couple of points to note in the video:

Even though it appeared the Tower was going to be able to get the victim, the guys were still getting dressed out in order to perform a rope based operation should it have been necessary. It was a good job getting plan B in motion in case plan A didn’t work for whatever reason.

The worker hanging in his harness was staying relatively still while hanging. As noted by Dr. Roger Mortimer in his 2011 ITRS presentation, it is the lack of motion while hanging in a harness that seems to cause Suspension Trauma, Harness Hang Syndrome, whatever you want to call it. The point is to get the people to move their legs if they are at all able to. Here is a link to his published work on the topic:

Last, it looked like the bottom end of his safety line was entangled with the scaffolding and pulling tension on the line across his body. I don’t know if that means anything or not, but it should be a consideration during size up.  If the Tower was unable to get to the worker, it’s possible they could get to that safety line and free it up if it were causing issues.

Thanks to Collin Moon from Elevated Safety for pointing us the recently released PBS and Frontline half hour documentary taking a look at the dangers of the cell tower climbing world and who is ultimately responsible for the safety if the workers.

There are several layers of sub contractors between a major carrier like AT&T and the guy who is actually climbing the tower to do work. Because of time pressures and the contractor at each level taking their cut of the pie, the result is that climbers feel pressured to climb without taking proper safety precautions, like tying off, while at height.

While the report is insightful and eye opening, it seems like it is looking to place blame on one group or another. It would seem to me that regardless of time pressure, OSHA mandates, etc… that the worker themselves has the ultimate responsibility to save their own life. The race to the bottom of doing the work on these communications towers is both literal and figurative and looks like it will only continue if people are willing to do things like free climb a tower in order to make $12 an hour. Keep in mind that my thoughts on this are formed having never worked in the communication tower industry, however, I’ve been aware of the effects of gravity for some time now.

Somewhat related is the recent release from New Zealand’s Department of Labor and the unfortunately acronymed Industrial Rope Access Association of New Zealand (IRAANZ) of new best practices guidelines in answer to three workers falling from height over the past year. That’s a lot of falling in a small country from an industry that has a great safety record thanks to groups like SPRAT and IRATA. Here is a link to the Best Practices guidelines:
