mobilus was looking for pics and info, not safety recommendations. That said, it scares the hell out of me. On the farm this wasn't necessarily the most dangerous task. No one got hurt cutting wood, but baling hay did seem to cause more harm and damage.
You make an excellent point. I guess one's outlook on safety is relative to their experiences. I see people free-climbing mountains on TV and think that they've got a screw loose. Maybe that comes from a 30-foot fall I took as a young man. I was hit by a semi truck and trailer about two years ago, and now I know not to stay alongside of them as I pass, or they pass me. I teach aircraft mechanics and make sure to stress the danger areas by relaying accidents/incidents from the past. The past...learn from it or you're doomed to repeat it, right? Well, there are some things we love to repeat (not doom), and things that rightfully scare the hell out of us (doom).
The level of safety indoctrination at the time of the photo from bartsdad was nothing like it is now, with the overcompensating actions of our government. The Consumer Product Safety Commision does some good work, I guess; but they also over-reach their purpose and ban things in deference to political agendas that have nothing to do with safety. Take the "green movement" and their ban (now terminated) on youth four-wheelers and dirt bikes because they contain too much lead. Duh, it's called a battery. And their attack on second-hand stores...get real. But the government will continue to be the "nannny" in every way we allow it.
As far as farm work goes, I know it well. I grew up in a farming family. We've lost loved ones to horrific accidents. And looking back on some of them, we now ask if there wasn't a better way to do whatever. Sometimes there is, sometimes not, and sometimes the inherent risk is something that we accept. Operational risk management, so it is called. In the photo we see an open blade, and kids doing the work, but the oldest kid or father is nearest the danger - so at least the danger was recognizeed.
We may see a time when heating our homes dictates more risk than setting the thermostat.
