A 21 × 9 cm sterile tie-on mask, for a fully adjustable fit when loops interfere with a hood or beard cover.

Construction

Ties allow independent adjustment of the upper and lower edge, which is the practical answer for operators wearing a beard cover or a tight hood. The 21 cm width gives coverage without pulling.

Where it is used

  • Aseptic gowning with facial hair
  • Operators who cannot get a stable loop fit
  • Grade A/B support areas

Handling notes

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