An 18 × 9 cm tie-on mask for a fully adjustable fit, typically specified where loops interfere with hoods or respirators.

Construction

Ties allow independent adjustment of the upper and lower edge, which is useful for smaller faces and for operators who wear a beard cover or hood underneath.

Where it is used

  • Aseptic support gowning
  • Operators with beard covers
  • Visitors and contractors
  • Areas with respirator compatibility requirements

Handling notes

Tie-on masks require a mirror or a trained buddy for correct fit. Build the step into the gowning SOP rather than leaving it to habit.
