23. C50 Protective Mask Initial Sizing and Fitting

24. Warnings, Cautions & Notes WARNING 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. NOTE 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.

25. 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:

26. Sizing Gauge Familiarization Sizes User Diagram *Directions on the reverse side Eye Location Guide

27. 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

28. 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.

29. 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

30. 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

31. 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

32. Installation Reach inside facepiece and hold nosecup away from vision correction assembly Place the vision correction support frame on the stand-off and push it down Flex the facepiece in the temple strap area on the left or right sides mask; gently push the support frame-mounting tabs into the vision correction support frame receptacle Vision Correction Assembly Receptacle Mounting Tabs Stand Off Support Frame

33. Don the mask; eyes should be centered, if not determine which direction the adjustment should be made – up or down Doff the mask Loosen the spectacle frame assembly cam lock Slide frame assembly up or down to adjust Lock in place with cam lock Re-check to ensure the stand-off is still in place Don and recheck adjustment Vision Correction Adjustment Cam Lock

34. Mask Fitting Procedures • Loosen all of the head harness straps completely • Ensure temple strap pivoting buckles remain open • Pull harness over front of mask • Have the user hold hair away from the face • Place chin in the chin cup of mask and have user hold assembly tightly against the face • Grasp harness tab and pull over the head • Pull all the way down • Adjust harness so that temple straps are parallel to the ground

35. Tighten cheek straps one at a time until snug against face Adjust brow straps one at a time until tight and secure in the brow strap covers Adjust temple straps one at a time until snug Close pivoting buckle clamp plate securing the temple straps in place Fitting Procedures

36. 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

37. 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

38. 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

39. 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

40. 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 NOTE Ensure not to cut the internal drink tube too short or the warfighter will not be able drink while wearing the mask Fitting Procedures

41. 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

42. 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.

43. Preparation of the TSI Portacount CAUTION NO SMOKING/DIPPING WITHIN 30 MIN. OF TESTING WITH THE PORTACOUNT. NO SMOKING AROUND THE PORTACOUNT.

44. Preparing the Mask: Visually inspect the inside and outside of the mask Attach modified drink tube sampling adapter to the drink tube coupler. Have user don the C50 Turn the drink tube lever to the ON position Caution: All water or foreign material must be expelled from the mask drink tube before the sample tube can be connected. BLOW SERVERAL TIMES TO CLEAR. If obstruction cannot be removed, the mask should be returned for maintenance. Preparation of the TSI Portacount
