how much do these people earn?
going up would be scary
but imagine going down!

what makes it a killer video is the fact you keep thinking he gets to the top, but it just means a smaller more dangerous looking ladder

d=1/2a(t)squared

1768 feet = 539 meters

539=1/2(9.81)(t)squared

539= 4.9 (t)squared

110= (t)squared

10.4 s = t

velocity = at

v=9.81(10.4)

v=102 m/s at impact

So, you would free fall for 10.4 seconds(assuming no wind drag) and hit the ground at 102 m/s if terminal velocity were non-existent.

In the video, he said this:
• Free Climbing
• no safety lines used.
• easier and faster.
• attaching, climbing, detaching, and removing safety lines every few feet, slows progress and is tiring.

• Personally, I have been in situations before, where my employer was very strict about following OSHA guidelines. There were times, when the leaning, reaching, and awkward positions I put myself in, just to secure the lanyard, were much riskier than the actual work itself.

However, not everything he said, is entirely true. There are other pieces of hardware/equipment, that are made for this exact reason. These bypass his reasoning, because there is no need for attaching, detaching, reattaching, every few feet.

Obviously, the cable needs to be there. If there is no cable or rope, then these do nothing. If there is a cable, these provide safety, while minimizing and/or alleviating the repetitive action of reattaching the lanyard every few feet.

GME Supply Safety Cable / Wire Rope Grabs are precision-crafted for vertical fall arrest protection, and are built tough to withstand years of use. The cable grab device is a cam activated fall arrester which slides freely up and down a 3/8" (10mm) steel safety cable wire, and locks up on the cable to arrest a free fall. Works great on both galvanized and stainless steel cables. Includes bonus pouch for storing your safety cable device.
