The Importance of Fit Testing

FFP3 NR masks must provide maximum protection for every individual wearer. It cannot protect the wearer if it leaks. One of the key reasons for leaks is due to poor fit – a proper seal needs to be made to fit securely on the wearer’s face to ensure effectiveness.

Due to differences in face shapes and sizes, it is unlikely that one particular FFP3 NR mask will fit everyone. Therefore, fit testing is carried out to ensure that the mask is selected to suit the wearer. The fit check procedure involves:

  • Cover the front of the respirator with both hands, being careful not to disturb the position of the respirator.
  • Exhale sharply. If any air leaks around the nose, readjust the nosepiece as per fitting instructions. If air leaks at the respirator edges, adjust the position of the respirator and / or tension of the straps.
  • Retest the seal.
  • Repeat the procedure until the respirator is sealed properly. If you cannot achieve a proper fit, do not enter contaminated area. See your supervisor.
