Very interesting! I worked for Ford for 38 years. Things hadn't changed a lot from 1936 to 1986 in some respects. In 1986, sheet metal workers still used a gloved hand to check for flaws. Until a couple of years later, there still wasn't a sensor able to detect surface flaws as easily as a human hand.
I noticed, that in the fender and roof section presses, they already were using the two-hand switches to keep hands out of the press.
The fixtures used to flip the frames and deck the completed bodies is now rigid. No swinging parts or fixtures in the plant today. And the work rises to the worker on "benches". No more stooping and bending, for the most part.
I don't think anyone needs a 32oz hammer any more to fit rivet heads.
In the 1970's I moved from Ford's Kentucky Truck Plant to the auto assembly plant across town, so I wasn't at the plant when this accident happened. My dad's maintenance crew had to repair a floorpan press. They had insured that everything was locked out, and that the power was completely off before the crew went in and made the repairs. After the repair was finished, and the press tested, my dad signed off on the repair and sent his workers on to other jobs. When he was about 100 feet from the press, he got an emergency call on the radio. One of his electricians had dropped a knife under the press bed, and had gone back to retrieve it. He only stopped the operator, went under the top of the press, and tried to get his knife. The press cycled and crushed the man. My dad got back to the press in time to see the man try to raise himself up. This was in the days before EMS services. They called the county police, who got there in about ten minutes. My dad went to the hospital with the police and his electrician, but the man died on the way. Even in forty years, people still take unnecessary risks.
