It’s incredibly unsafe when you live in a society built around smartphones/tablets for health and safety tools to remove said smartphones.
But is it? Landlines can make the same emergency calls. A Faraday cage also doesn't mean you can't have an internal wifi that reaches outside that the staff can connect to, or even the students can connect through with a proxy controlling their connection.
I agree it's impractical. But it doesn't mean laptops and phones suddenly don't work. They can still work within the cage and you can poke holes through it with a landline and a proxy to control traffic in and out.
Ultimately, it's definitely not worth the engineering and the effort. I just don't think that safety is the reason it is impractical.

They're at the front of every classroom near the teacher. Along with several in the front offices, even the nurse has one. That wasn't difficult.
Have you ever done an active shooter drill? Teachers don't hang near the front of the classroom.
I've done active shooter drills in the military. The first thing you do is cover the window in the door, which is often by the front of the room where the phone is. The beauty of a landline is that it doesn't move. You can dial out to 911 and they know exactly what building you're in without you having to even tell them. The teacher doesn't need to hang out at the front of the room.
Yes, active shooter drills are exactly the same for the military as they are for schoolchildren and teachers.
What is different? Cover the windows to hide the number of people, hide, and barricade. You're also very conveniently ignoring the rest of the comment that addressed your concern. Care to try again?
