Imperative sentences can be made passive but usually not used, especially in speech.
For example, PLEAS OPEN THE DOOR can be changed to passive voice as LET THE DOOR BE OPENED, PLEASE or THE DOOR SHOULD PLEASE BE OPENED.
Likewise, negative imperatives can be transformed.
DON'T OPEN THE DOOR, PLEASE - DON'T LET THE DOOR BE OPENED, PLEASE.
