Dude -- You are operating from the false(!) premise that the guard on your machine is identical to the one on Alan's. In your first post, you wrote: "I think someone didn't install the plastic guard." Alan's machine did NOT come with a guard that fully encloses the blade on the left-hand side of the saw. My saw, an original Delta, also with an original Delta riser block, does NOT have such a guard. The saw -- as designed -- is dangerous in this respect. That was the entire point of Alan's video! It was an alert to those of us who have this type of saw that we should do something to protect ourselves from this design 'defect'.
It does not help anyone to turn this into a moral failing on Alan's part. The guard you suggest he neglected to install did not come with his saw. The part does NOT come with the riser kit sold by Rockler. Take a look at this picture from Rockler's website:

The picture shows the riser block and the blade guard installed on the saw. The slot through which the blade runs is completely open to the front. The blade guard on my saw is virtually identical, except, being a Delta that dates back to the 1970's, the guard is made out of metal. But, like the Jet version, the slot is uncovered. I currently have a 1/2" blade installed on my saw. The blade is properly centered on the wheels. The tips of the blade's teeth are below the sides of the blade guard. Yet, I can feel the tips of the teeth with the pads of my fingers. If the saw were running, I'd get cut. I wouldn't lose a finger, but it would be a nasty cut. Allow me to stress: This is with a properly installed 1/2" blade on a saw that has ALL of its safety guards in place.
Nor does it help to suggest that Alan was somehow lax in his attention to safety. Allow me to reiterate that I used to run one of these saws in a furniture mill and was responsible for teaching others how to use the saw safely. Until Alan posted this video, I had no idea such an accident was even possible. I've used a Delta 14" bandsaw for hundreds of hours. I know the saws very well. Yet, I had no idea I could be cut on the left-hand side of the saw! It's hard to follow a safety rule if you don't know it exists. It's also hard to avoid a danger you don't know is there. This is why safety rules are taught. We cannot rely on 'common sense' or 'being aware' to avoid accidents in the workshop. Instead, we need to rely on safety rules that were learned by analyzing the injuries suffered by the thousands of woodworkers who passed before us.
Lastly, allow me to address why I'm harping on this: Saying, as you did, that Alan's injury was the result of a combination of laziness (not installing the guard), laxness in safety, and stupidity, does no one any favors. It tells those of us with similar machines we need not worry -- because none of us are similarly lazy, lax, nor stupid. Worse, it tells the rest of us that we risk being run down on the internet as lazy, lax, and stupid, if we alert anyone to a potential safety issue. Laying this at Alan's feet discourages us from learning from his accident and it discourages the free flow of safety related information.
