I don't have photos, but I've seen two unfortunate accidents, a brutal splinter and had an unpleasant near miss myself:
The first accident was caused by someone climbing on the mechanism of a jammed tilt hoist to clear it, when they freed it, it immediately began to cycle and dropped onto their lower leg. Luckily he only sustained a closed fracture and some tissue trauma, he made a full recovery in 4 months and was disciplined for breaching the H&S rules by entering the feed mechanism without locking it out.
The second was caused by a piece of metal banding that got caught round a drivers leg whilst he was boarding the cab of a sideloader, the other end became entangled in the wheel of the vehicle and when it pulled tight cut into his ankle, he was lucky not to sustain a traumatic amputation and that the band acted as a tourniquet on the injury it caused... He lost most of the function in his right foot though due to the nerve damage and extended period of interrupted blood flow.
The splinter was a 6" long wedge of redwood ejected from under the guard of a spindle moulder, the piece broke up after the cutter met a hidden defect and that segment was ejected into the palm of the hand feeding the wood (two fences and stops for cutting partial length rebate, as long as the guides and guard are in place the hand should never be able to reach the danger area, obviating the need for a push-stick). It didn't do any major damage, but still required an x-ray and attention by a surgeon to prevent tendon damage removing it... the spindle was also out of action until they devised an even closer fitting guard.
My near miss was with a big SET machine, again the cutters hit a defect and ejected a lump of timber 2"*3" which escaped the partial enclosure and flew into the walkway opposite... It struck me in the right pec and left a really deep brusing which eventually ended up extending over nearly a quarter of my torso, after the near-miss report was filed a small chicken wire fence was placed behind it to prevent any further material being ejected into the walkway.
