For the testing plants unit assignment, we were asked to find out what to do in the event of potential poisoning.
In the Netherlands, we are told to immediately call 112.
I also found a handy app which I downloadeded, EHBO (Red Cross), which directs you through what to do in several situations including, poisoning, heavy bleeding, unconsciousness.
It tells you when to call the huisarts and when to call 112, and has a button that connects you directly to 112, and tells you things like not to give milk or anything else unless directed to do so by a medical professional. It also shows you step by step how to perform CPR.
