C50 Protective Mask

Initial Sizing and Fitting


Warnings, Cautions & Notes


WARNING User’s safety depends on properly sized and fitted mask assembly.

Before putting on and adjusting mask assembly, users shall remove all hairpins, combs, hair knots, buns, or braids that will interfere with mask assembly seal. Users must be clean-shaven to prevent mask assembly leaks.

DO NOT wear contact lenses (soft or hard) while wearing CB Protective Masks. Inadequate oxygen supply to the corneal surface, exposure to dust, dirt, and smoke/gas may cause serious vision loss or eye damage. Users requiring vision correction are provided optical inserts for their protective masks.


Masks are to be cleaned as often as is required. However, MASK MUST BE CLEANED AND SANITIZED BEFORE TRANSFERRING TO ANOTHER USER.

Initial sizing and fitting should only be accomplished by trained personnel and is conducted without the hood installed.


C50 Facepiece Sizes

  • The mask is available In 3 sizes to fit most of the adult population
  • Twin port filter mount accommodates left and right hand shooter
  • Size is molded into mask above visor
  • Typical sizing % for a team are listed below:

Sizing Procedures w/Sizing Gauge

Note: It maybe more convenient to size and fit using a sizing set consisting of 1 of each size C50. Once correct size is determined, a new mask can be issued

  • Place the gauge to the face diagonally along the line from the point of the chin to the widest point of the cheekbone.
  • Read the size of the mask where it touches the cheekbone.
  • If between two sizes pick the larger size
  • Have the user don the selected mask, and assist in correctly tightening the straps
sizing procedures w sizing gauge cont
Sizing Procedures w/Sizing Gauge Cont.

Note: ensure the your eyes are at the same level as the users.

  • Using the eye locator on the gauge, locate the bottom edge of the guide on the rubber lip at the bottom of the eye lens. Locate the “Top of Lens” mark with the top of the eye lens.
  • If the pupils are within the “correct size” zone the mask is properly sized.
  • If the pupils are in the “too small” zone, select a larger mask. Repeat the last three steps.
  • If the pupils are in the “too big” zone, select a smaller mask. Repeat the last three steps.
alternate sizing procedures
Visually assess the size of the user and select the most likely size mask

Have the wearer hold the selected size mask on their face with the chin positively located in the chip cup

Pull the head harness over the head and tighten the cheek, brow and temple straps

Check to see that the center of the pupils is slightly above the centerline of the visor

If the eyes appear to be too high, the mask is too small; if they are too low, the mask is too big

Alternate Sizing Procedures
alternate sizing procedures1
The mask should make firm contact with the face around the entire perimeter of the facepiece

The distance between the edge of the mask and the lobe of the ear is typically in the range of .5 to 1.5 inches

If the distance is less, then the mask is probably too large and gaps at the forehead and chin may be observed

If the distance is greater, then the mask is too small and may appear to be perched on the face

Remove the initial mask and issue the warfighter the selected mask size

Alternate Sizing Procedures
fitting procedures
Remove the mask and issue the correct size to the user.

Clean the sizing masks for next fitting

Assist the user in donning the correct size mask by:

Open a CBRN F12B or CTF 12 Filter and install

Ensure microphone is installed if required

Install optical correction if required

AVON recommends that canteen caps be changed to the Avon canteen cap at this time.

Fitting Procedures

Fitting Procedures
checking mask for fit
Check position of temple and cheek straps

Temple straps should not be cutting top of ears

Temple straps should be parallel to the ground

Cheek straps should not be cutting bottom of ears

Checking Mask for Fit
  • NOTE
  • Once the mask is adjusted correctly, DO NOT ADJUST the brow and temple straps again. The mask is now fitted and adjusted correctly. Only the cheek straps need to be loosened or tightened when donning or doffing the mask
checking mask for fit1
Checking Mask for Fit
  • Recheck that the eyes are centered
  • Straps do not cut into ears
  • Mask assembly pressure
  • Bottom of mask assembly does not cut into the throat
  • Skin in front of ear is not wrinkled
  • Nosecup does not obscure vision
  • Edges are flat against the face and not rolled under
negative pressure test after initial fitting
Have user place palm over outlet valve and blow outward with large breath

Them place the palm over the inlet hole of the filter and breath in. Mask should collapse against the face and remain there while holding the breath. If it does, fit is correct.

If it fails check the following and repeat the negative after each one

Negative Pressure Test After Initial Fitting
negative pressure test failure checks
Check for hair, clothing, or other matter interfering with seal

Ensure headharness is pulled down as far as possible

Ensure edges are flat against the skin

Have warfighter feel for air leaks by feeling for incoming air

Adjust straps as required

To correct leaks around throat area lift up on mask

If still does not seal try another size or different mask

Negative Pressure Test Failure checks
fitting procedures2
Size the internal drink tube

Turn the drink lever upwards to reposition the internal drink tube towards lips

If it is too long, doff the mask and pull the internal drink tube out

Cut internal drink tube behind the first barb

Reinstall internal drink tube

Repeat to achieve the proper fit


Ensure not to cut the internal drink tube too short or the

warfighter will not be able drink while wearing the mask

Fitting Procedures
fit testing
Once all three steps are complete, the mask must be fit tested.

This is done using the TSI Portacount Test System

Before either of the tests begin, the mask must be set up properly.

Fit Testing
fit and leak test theories
Fit and Leak Test Theories
  • Just because a mask is worn does not mean that the user is breathing clean air. If the mask is donned improperly or it is not functioning correctly, articles can enter the mask through various leak paths.
  • When a leak exists within the mask system, the user is not properly protected.
  • These tests ensure that the user is wearing the mask properly and that the mask is functioning properly.
  • Mask fit testing is performed by sampling the air inside the mask and comparing this to the amount of particles contained in the air outside the mask.
