straps so that the respirator ts securely to
your face.
7. Press the nose clip with fingers of both
hands so that the respirator can be attached

same time when donning; otherwise, your face may
get injured by a corner of the respirator.
<Removing the respirator>

CAUTION
In order to prevent the secondary infection, special
care must be taken not to touch the surface of the res-
pirator when taking o󰀨 the respirator.
■Proper tting
In order to achieve the original performance of the respirator, the respirator must
have best t. The user is required to be t tested according to OSHA 29 CFR
1910.134 either qualitatively or quantitatively prior to use. Conduct a t check
following this procedure every time you put on the respirator.
1. Wear the respirator in the same manner as
you actually conduct during work.
2. Cover the respirator with two hands and exhale.
If it is not possible to cover the respirator
with both hands, use a polyethylene sheet
to cover the surface of the respirator, hold-
ing it down with both hands and exhale.
3. Check that no air leaks through respirator-to-
face seal when you exhale. If you feel air leak-
age, adjust the position of respirator and/or tention of straps until the air leakage stops.
WARNING
1. Before using the respirator in an actual operation, be sure to con-
duct the inspection whether the respirator is properly tted or not.
2. If it is not possible to ascertain that the respirator is properly tted,
do not use the respirator in an actual operation. Make the neces-
sary adjustments so that the respirator rmly ts your face.
If it is still not possible to ascertain that the respirator
is attached properly after those adjustments, inspect
each and every portion of the respirator at a safe
place.
(Please refer to “Check before donning”.)
<For your reference>
If your face is too small to t properly to your chin, it is recommended to put the
bottom strap over the back of your head as shown in the gure below so that the
respirator is tightly tted around the chin.
■Storage Method
Store the respirator in a clean, cool, dark and dry place.
CAUTION
Do not pile up or bend the respirators to store ; it may
cause problems such as ssures, deformation, etc.
■Disposal Method
