What does "interruption-proof" mean

Question

Read alone unless you are working  with other readers.  Family members, friends, or others who are not in a study mode may interrupt your concentration.  If you prefer to read  alone, establish a relatively interruption-proof place and  time,  such as an out-of-the-way spot  at the library or an after-class hour in an empty classroom.
