They should show those accidents if they are on camera.
I wasn't a "real medic" in my squad when in Afghanistan (I say "real medic" because I'm not sure what it actually means in my language).
But I did get weeks of extensive first aid training for critical stabilization and all that.
One of the way they taught us to truly understand or expect the severity of injuries was to show how little it took to mess up the human body.
The "flesh is weak" is not just a Warhammer slogan. It's a literal fact
I saw what felt like dozens of recordings and pictures of people being ripped apart just from driving a little too fast.
I have had MAXIMUM respect for vehicles since then. I always drive ONE HUNDREDED PERCENT SAFE because of what I saw.
I am sure a lot of workers would learn to respect the true power of their machinery if they experienced something similar.
