Correct but someone who is between the ages of 14 to 17 is considered a juvenile, and not a child. This dude was almost 18, in 2 months time, legally he’s an adult, in 2 months time, he isn’t going to magically mature into a less dumb person.
But somebody at that age shouldnt have to work a job that is operating heavy machinery like that. Obviously there’s going to be frequent injuries when somebody young works in positions like these.
