I don't see this as an equipment choice issue as much as I see this an education problem. It is really easy to buy a bunch of gear, look at someone on YouTube or Facebook use it and THINK you know whats going on. Work at height is all for the most part the same, what changes is what type of job you are on that day (example being, a large Oak removal, a small Maple pruning, Caving into a 1000 ft muddy pit, ice climbing in -30 degree weather, oil rig work in 100 + degree weather in the middle of the Gulf of Mexico). All of these are at height, all have the potential for side loading different things, all can have fall factors or swings, and ALL need an education to safely do. Why does the industrial world do what they do with rules and regs? Because all the training is the same across the board. If I go do work for a SPRAT company or IRATA company, I will be climbing under the same rules and teachings as the guy or girl next to me. Sure they may know some tricks or have more experience but the fundamentals are always the same. The problem comes up even in the industrial world when people with no training go do work and get hurt, kill them self or need to be rescued. That is when the regulations come in and insurance companies start having a say. There has to be some type of span of control, from industry, local labor law, or as simple as in house. I doubt anyone worth their weight would allow some new guy to the company to come in and climb on a obvious bad system, nor would I think you would let them climb on a system that you as a manager or foreman had never seen without asking basic questions first about. No one likes to be told how to climb, but we have to police our selves for safety. I do wonder sometimes that if someone had come along and told tree climbers they MUST climb SRT if it would have ever been a popular means of climbing as it is now? Even if that same person told everyone they were doing it for the betterment of the climbers body, energy conservation, safety, things of that nature. It would be as insane as saying you should climb double static line because you are always tied in twice and have a redundant system in the case one were to fail (a safety factor). The bottom line is you have to personally keep your self educated, no one will go out of their own way to do that for you.
