This is Will You Be Here Tomorrow?, a 1994 workplace safety video sold by the United Safety Council. It imagines the worst case scenarios for industrial and warehousing jobs. It is extraordinarily blunt, using somewhat subpar visual effects to illustrate nails being driven into eyeballs, severed limbs, crushed skulls, and, at the 2:10 mark, a acetylene tank turned into a missile.
I worked in a warehouse to put myself through graduate school. It was filled with sleep-deprived people driving 13,000-pound forklifts as fast as they could to make impossible production quotas. It's amazing that people weren't killed there every day. Perhaps it's funny, but I could also see this safety video making an effective impression on workers.
