• In an environment where the oxygen concentration is less than 19.5 %.
• In an environment where contamination materials are unknown.
• In an environment where there is toxic gas, vapor, or oil mist.
• In an environment where contamination materials pose immediate
danger to life or health.
2. Never use the respirator except for the specied application

7. Do not wash the respirator, otherwise the lter efciency may
decrease.

compressed air because it may cause a decrease of lter ef-
ciency.
9. This respirator is sensitive to shock. Do not bang or slam down
the respirator because it may cause a decrease of lter efciency.

conforms to the “Guidelines for prevention of tuberculosis infection in medical
facilities” set by the CDC (Centers for Disease Control and Prevention).
The respirator shall not be used in the following conditions:
1. In an environment where the oxygen concentration is less than 19.5 %.
2. In an environment where there is toxic gas, vapor, or oil mist.
CAUTION

strap hanging around your neck.
CAUTION
In order to prevent the secondary infection, special
care must be taken not to touch the surface of the res-
pirator when taking off 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, holding 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 leakage,
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”.)
■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
Put the used respirator in an airtight bag to prevent the particulate matters from
scattering before disposal in accordance with the applicable laws and regula-
tions.
