Well, keep in mind the audience for that site varies widely, from the most junior Marine rifleman to the saltiest Command Master Chief. Take a look at the number of hard copy magazines the Safety Center puts out for the various Navy communities to get some examples. It's also not meant to cover just really dumb dangerous stuff that has happened but in the spirit of Operational Risk Managment get shipmates to think "what are the consequences" if even mundane stuff goes awry. It's all about breaking a link in the mishap chain before the mishap occurs.
Spent several months at Naval PG school in Monterey learning all about this and they rarely publish the truly gruesome stuff. I had a buddy lose his left hand ejecting from an EA-6B when his Timex G shock got caught on the centerline canopy bow. Degloved everything but the base of his thumb and he's one that lived. Vince had a great atitude about it afterward figuring the alternative was a deep smoking hole in the ground in the Olympic mountains. The Navy made him specialized hands for everything he wanted. As he was a triathelete he even had hands for swimming and biking. That was over ten years ago so I'm sure he has something even better now.
