In the old days with R12 refrigerant, you could have killed yourself with hooking the low side hose to the high side of the system, since a can of refrigerant was never designed to hold a pressure exceeding 300 psi. But with R134 it is pretty idiot proof since the connectors are not the same size and a low side connector can not fit a high side connector, but there is always that one idiot that will MacGuyver something together and end up killing or hurting himself or other people.

Best advice is if you don't know refrigeration system take it in.
