How long should it take you to don the protective mask and ensure airtight seal?

Answer 1

9 seconds

Answer 2

It depends on the type of mask and the individual's level of familiarity with it. Generally, it should take less than a minute to put on a protective mask and ensure an airtight seal if the person is familiar with the process. However, if it is their first time using the mask or they are not familiar with the correct procedure, it may take slightly longer.
