Centre for Health Protection - Use Mask Properly

Face mask provides a physical barrier to fluids and large particle droplets. Surgical mask is a type of face mask commonly used. When used properly, surgical masks can prevent infections transmitted by respiratory droplets.

People should wear a surgical mask when they have respiratory infection; when taking care of patient with respiratory infection; or when visiting clinics or hospitals during pandemic or peak season for influenza in order to reduce the spread of infection.

Points to note on wearing a surgical mask

  • Choose the appropriate mask size. Child size is available for selection as indicated.
  • Perform hand hygiene before putting on a surgical mask.
  • Avoid touching the surgical mask after wearing. Otherwise, should perform hand hygiene before and after touching the mask.
  • When taking off tie-on surgical mask, unfasten the ties at the nape first; then unfasten the ties at the crown of head. For ear-loops type, hold both the ear loops and take-off gently from face. Avoid touching the outside of surgical mask during taking-off as it may be covered with germs.
  • After taking off the surgical mask, discard in a lidded rubbish bin and perform hand hygiene immediately.
  • Change surgical mask timely. In general, surgical mask should not be reused. Replace the mask immediately if it is damaged or soiled.
