Borderline negligent, though, on the part of the instructor. Lab assistant or supervisor should have been double-checking safe handling of something that dangerous.
he can't be expected to keep track of something for 2 minutes without someone watching over him, but we can let the fellow operate a car, have mains power in his home, purchase cleaning chemicals, etc?
loads of graduate students in the physical sciences are regularly given access to stuff that dangerous or worse. if we've got to have somebody watching over each and every one of them, graduate education will grind to a complete halt.
You are supposed to get training when dealing with anything different and dangerous. Say you rock climb for the first time... and the instructor talks to you for 10 minutes about various stuff and somewhere in the middle he says: "and make sure to check that you can't see 'danger' written on the clasp of the harness, you may fall if it's not secured properly". You have lots of stuff to think about... your posture, the grip, the path you want to take... in a group of 10 people, is it really that unlikely that one will simply forget?
That's why the first couple of times somebody more experienced will check everything about your harness.
Really? We have to hand-hold adults that much now? We worked with chemicals that could cause serious injury in freshmen chemistry. The instructor did an extra "yes this stuff is really dangerous" warning those weeks, but it was a bunch of 18 year olds.
This was a Masters level student, so I don't feel like the instructor has any blame here

and what will the training for remembering to close a box consist of? your posture, the grip, the path the lid will take?
checking that they closed the box.
