With all the stories about people getting violent in hospitals,

Perhaps they have an actual Dr Strong working there. We have a Dr Strong in our county, but he is a Veterinarian.

I've been assaulted three times while working retail since the pandemic began.

Security in out small hospital in a small is pretty minimal. Usually only one or two unarmed uniformed people. I haven't been there since the pandemic, but I'm sure they've increased it. There are fewer unlocked doors and they are manned by security. Before I could have walked in there with a bomb and not be challenged. I used to walk in there at 6 am carrying a bag with my laptop and walk the length of the building usually without seeing anyone.

These guys could take care of any trouble.

I went to post the same thing and had to log back in.

I don't remember all of them, but what I do remember is as follows:

Code Blue: Medical Emergency / Cardiac Arrest (duh)
Code Red: Fire / Smoke Emergency
Code Pink: Baby Missing / Child Abduction
Code White: Violent Patient / Visitor
Code Black: Bomb Threat
Code Silver: Armed Intruder

There's so many of them now that they attach a card to your employee badge listing them

They have it listed for anybody to see at each nurses' station.
Saw it when my dad was in the hospital.
That was 20+ years ago so it might be different now.
But, IIRC, the color code was the same.
I remember a Code Green meaning that trauma conditions were abated. That hospital is a Class II trauma center, so they'd get big interstate accident events, or things like tornado. Class II is pretty much prepared for everything but burns & one or 2 specialties. (This hospital doesn't do brain trauma, either.)
My wife's good friend used to work in ER admitting there. She told us a few stories about 20 or 30 people being brought in with severe injuries from a single event. Pretty intense, I guess.

Before.
