Actually not a problem. Have lock boxes for each person front and back for personal items. Once at hospital lock it away. It can be done w.o drawing attn. I am in and out of our lock cabinets all day so my partner would never know.
Actually, once the weapon and person is detained, their employers are notified as their policies clearly state "NO guns". One hospital I worked at did have a special locker for employees to put their weapons in when commuting through the riot areas. That was over 20 years ago. While there is still violence, people have not felt the need to carry a weapon to work even if they still keep it in their house for protection. I rarely care mine in the car but still keep a couple of weapons at home. I am not anti-gun but I have seen what EMS attracks and there is no way I want those who already have a whacker view of this profession now joining just for the chance to carry a gun to be really cool. Or, joining the local EMT class because the Police Academy tossed them out.
