I worked in geotech consulting and there is one piece of radioactive equipment used for soil testing that requires a certification to operate and transport in a vehicle, called a nuclear density/moisture gauge. Every year there’s an article that makes the news where a technician forgets to strap down the equipment so it doesn’t fall out the truck or not locking the box that holds the equipment and someone steals it. People really are stupid and lots of companies that give out work trucks don’t teach employees basic safety especially when towing or transporting fragile things.
We are just repeating history if he indiscriminately puts tariffs on businesses.
