Wish I had that class in my security days.
After being in MA for over 20 years, I had to go though a restraint course at a Catholic Hospital I once worked at. Restraint meaning how to restrain combative patients while not hurting them. It was given by a nun. It was the most ridiculous class I ever had to endure. I actually told the nun that one of the techniques she was teaching "Absolutely would not work" Slapping someones had away that had your hair...nope, not working. Grabbing that hand and bending over to create a lock and cause pain would. But no, we could not hurt the combative folks brought in by the police and left for us, nor could we hart those patients who were most definitely trying to hurt the staff. She should another lock, that did work, but she end it with "now juts push them away" I said, "No disrespect sister, but if I had to grab them and lock them, I'm riding that sucker all the way to the wall. I'm not pushing them away so they can come attack me, or a nurse, or a doctor again.
Oh ,adn to restrain a combative patient, and take them to the floor, you needed 5 people, two for each arm, 2 for each leg, and one to cradle their head so they didn't get hurt..... I did not even take part in that bit of the training. My reason, if I am called, frankly I may not have time to wait for 4 other people to show up.
Only once did I have a nurse, in a restraint situation tell me not to push on the patients legs like that, it could hurt them. I responded with, I can let go if you like, but I absolutely guarantee he will kick you right in the head. She stop telling me what to do.
This hospital by the way had a mental health and a detox ward and I had 60 confrontations in 3 months on average.
