Do not/ get panicked/ in emergencies/ no error. I think,here 'panicked' is an adj, and hence 'no error' . If it is not so....then please suggest the right ans...
Do not get panicked in emergencies.
is okay. But whether you want to write it that way is a second point.
Why not simply say:
Do not panic in emergencies.
It says the same, and it's easier to read.
