     How to Use High Filtration Surgical Masks

  1.     Perform hand hygiene before putting on mask
  2.     the correct size of the mask and ensure there are no defects 

 Procedure of Inserting High Filtration Surgical Mask

 Hold the mask in your palm with the nosepiece at fingertips. Hang head straps freely below head

Position the mask under your chin with the nosepiece up.

 While holding the mask in place pull the top strap over your head so its rests high on the back of your head

Using both hand mold the nose piece to the strap of your nose by pushing downward and outward

 Perform a fit check by placing both hands completely over the mask if air leaks around your nose adjust the nose piece

 Wear the right sized mask fit check is mandatory for all users of high filtration surgical masks and must be performed every time upon wearing

Perform hand hygiene after putting on mask

Removing High Filtration Surgical Masks

 Pull bottom strap over head

Maintain the hold on the first strap use another of to pull the top strap over hand

Do not touch front surface of the mask

It should be kept in a new clean Ziploc bag for reuse

Discarded

At the end of the day unless wet or soiled

Perform hand hygiene after removal of mask and after putting on the reused mask

High filtration surgical masks must e kept in cool and dry place
