What is the first step in inserting a foam earplug?

  1. Roll and compress the plug between your thumb and forefinger

  2. Wet it slightly

  3. Press it firmly into the ear canal

  4. Flatten the plug with the heel of your hand

The correct answer is: Roll and compress the plug between your thumb and forefinger

The first step in inserting a foam earplug involves rolling and compressing the plug between your thumb and forefinger. This action creates a smaller, tapered shape that allows the earplug to be easily inserted into the ear canal. Properly rolling and compressing the earplug ensures that it fits snugly and securely, which is important for creating an effective barrier against noise. Starting with this step is critical because a properly shaped earplug maximizes comfort and effectiveness once it's placed in the ear. Ensuring that the earplug is compressed allows it to expand and fill the ear canal once inserted, providing optimal noise reduction and safety for the user.
