1980, SRF Guam, USS Richland AFDM-8 a Floating Dry Dock that mostly docked SSN's & SSBN's We had an SSBN in dock & allot of things were being done to the boat all at the same time.... One of those tasks was a repair to the snorkel, it was raised and tagged out...(later investigation revealed a missing tag that had become dislodged & was on the floor) A member of the tiger team was working with his upper torso fully inside the snorkel when someone flipped the level to lower the snorkel.... He got mostly out but his right arm nearly up to the shoulder was sheared off, I'll never forget the scream.... I was about forty feet away & the second person to his side.... I wound up recovering his arm & packing it in ice.... He was evacuated to Hawaii where they unsuccessfully attempted to reattach his arm.... Rough deal...
I've worked around printing presses & high speed labelling for years... Ya gotta be aware of pinch points...
As was said earlier work from the back side of the pinch so it rejects rather then collects your body parts...
