The beginning scenes - no loose clothing, no rings or wris****ch, etc.
is good advice. I once worked with a guy that caught a ring on
something when he jumped down out of the bomb bay and tore the skin
off the back of his finger. Just pealed off a strip all the way from
the base of his finger to the fingernail. An Electrician, working on
the same airplane shorted out the main battery bank with his wedding
ring. Melted the gold ring right off his finger (that didn't do the
finger any good either)

As a young Airman those experiences convinced me that jewelry and
working are a poor combination and even today I automatically remove
rings and watches when going to work.

Yep. I like the name of the brand - Luna -
because I can't think of anything cooler than
to have your own base on the Moon Well,
maybe a time machine/battlecruiser/science
vessel/spaceship all in one...

I know of a trade school that had its carpentry students building a
house, that the school later sold as a fund raiser.

I was told that one long-haired student was on the 2nd floor, drilling
holes for wiring through the studs in the naked stud walls. He leaned
over as he drilled, and his long hair wrapped around the chuck of the
drill. The drill pulled his head down fast enough that he knocked his
head on the drill, then fell through the open stud space. He was rescued
while hanging by his hair about 8 feet above the ground.

Depending on how much hair the drill grabbed I would have expected to
find the guy on the floor with a nasty red place on his scalp where
the hair got pulled out :-)

When I was in the A.F. they were almost fanatical about safety. You
could actually be demoted for failure to comply with the safety
manual. When I retired and went to work for a civilian company I found
that while they gave lip service to safety they were actually far more
lax then the A.F.

From back in the days when machinists wore neckties! They were classier back then.

They probably didn't wear eye protection in 1914 either.

Yep, googling yields https://www.umassd.edu/about/historyofumassdartmouth/

Things have gotten much safer since then, of course. Safety inflation is real,
and obviously not bad up to a point. I taught an intro to machine shop lab
(just bare basics) and would come down very hard on a student who omitted
eye protection.

But I know the full-time machinist in that lab sometimes worked without eye
protection, just as I sometimes do on my basement lathe. It's a risk we take
based on our judgment of the circumstances.

OTOH, I don't think I've ever obeyed the "Never use without eye protection!"
warnings that seem to come on things like Harbor Freight screwdrivers. That
company probably puts warnings on its rubber erasers.

Kind of like this: https://www.youtube.com/watch?v=7gzDC-2ZO8I

I put plastic hats in the same category.

The expression for that is 'beyond parody'[1]. Example:

[1] this woman coined the phrase:

She's one of your people, Frank, but doesn't use her Polish
name professionally.

Back when I was working at it I wore USAF supplied corrective glasses
that were also classified as "safety glasses".

When I was in High School I worked one summer in a shop that had
machines similar to the photo in your UMass reference. The shop
belonged to two old brothers and apparently was originally built by
either their father or grandfather - my father remembered it being
there when he was a boy.

The first job that they gave me was making nuts... on a lathe that the
cross slide was calibrated in 128ths of an inch.

As an aside, one of the brothers had a Henderson four cylinder
motorcycle that probably dated to the 1930's sometime that was in
perfect like new condition. He would occasionally ride it to work if
it didn't look like rain :-)

A good choice for doing what?

If you're thinking of buying a mill, either get one with servo drives,
or one that is easily converted to CNC by adding servo drives. (I
don't like steppers). CNC makes things much easier.

That also means ball screws for the table. If the machine is sloppy
when operated manually, it will still be sloppy when driven by a
computah.

As for the safety lecture, it's all good advice. I would roll up my
sleeves, or use a velcro strap to keep them in place. The only real
accident I can recall was getting a sleeve caught in an industrial
sewing machine. Also, if you're using coolant, you'll never be able
to keep the machines as clean as the one in the video.
