3M 9928 User manual

Main Features
The 3M 9928 respirator provides lightweight, effective,
comfortable and hygienic respiratory protection against dusts,
mists and metal fumes. Its convex shape enhances wearer
comfort and allows a good fit over a wide range of face sizes;
the 3M™ Cool Flow™ exhalation valve reduces moisture
build-up, particularly in hot and humid work conditions.
The 4-point adjustable straps and adjustable nose clip ensure
a proper fit.
The 3M 9928 Premium Welding Fume Respirator has been
designed specifically for welding applications to provide
protection against Ozone and welding fume, plus relief from
nuisance odours.
The 3M 9928 does not require costly and time-consuming
maintenance.

Standards
The product has been tested to the NEW European Norm
EN149:2001 and has met the requirements of category FFP2
in this standard.
The main performance tests in this standard are:
• Total Inward Leakage
Ten test subjects perform a series of exercises while walking
on a tread-mill.The amount of contaminant leaking into the
respirator through the filter, face seal and, where fitted, the
valve is measured. For category FFP2 the leakage must not
exceed 8% for eight out of the ten results.
• Filter Penetration
The filter efficiency of twelve respirators is tested against a
sodium chloride aerosol and a paraffin oil aerosol.
For the FFP2 category both aerosol penetrations must be
below 6%
• Flammability
Four respirators are individually passed through a flame at
800°C ±50°C at a speed of 6 cm/sec.The respirators shall
not continue to burn after removal from the flame.
• Breathing Resistance
The resistance created by the respirator filter to an airflow of
30 L/min and 95 L/min are evaluated. For an FFP2 device this
must not exceed 0.7 mbar and 2.4 mbar at the respective flows.
• Information
A range of information, specified in this standard, must be
provided on the packaging of the product.
A full copy EN149:2001 can be purchased from your national
standards body.
Correct use
The respirator may be used in concentrations of solid, water
based and non-volatile liquid based aerosols up to 10 times
the Occupational Exposure Limit (OEL) BS4275:1997.
It can also be used to protect the wearer against Ozone gas
generated in welding applications in concentrations up to
10 times the OEL.

Fitting Instructions Warnings:
•As with the use of any respiratory device, the wearer must
first be trained in the proper use of the product.
•This product does not protect the wearer against gases
vapours, solvents from paint spray operations or atmospheres
containing less than 19.5% oxygen.
• 3M suggests the 9928 respirator for use up to 10 times the
Occupational Exposure Limit (OEL) of Ozone, and relief from
nuisance levels of organic vapours (i.e. levels below the OEL).
• Use only in adequately ventilated areas containing sufficient
oxygen to support life.
• Do not use when concentrations of contaminants are
immediately dangerous to life or health.
• Leave the area immediately if:
* breathing becomes difficult
* dizziness or other distress occurs
• Discard and replace respirator if it becomes damaged,
breathing resistance becomes excessive, or at the end of one
shift.
• Never alter or modify this device.
Respiratory protection is only effective if it is correctly
selected, fitted and worn throughout the time when the wearer
is exposed to hazards.
3M offers advice on the selection of products and training in
the correct fitting and usage.

1.Thread top elastic strap through
top buckles. Repeat for bottom strap
and buckles. Place the bottom elastic
strap around the head just below the
ears. Untwist the strap.
2. Place the top elastic strap around
the head, above the ears. Untwist the
strap.
3.Adjust tension by pulling tabs of
each strap, as shown. 4. Using both hands, mould metal nosepiece comfortably to shape of
nose.

5. Strap tension may be decreased
without removing respirator from the
head by pushing out on the back of
the buckles. If you cannot achieve a
proper fit do not enter contaminated
area. See your supervisor.
Note: do not use with beards or
other facial hair that may inhibit
contact between the face and the
edge of the respirator.
6.The seal of respirator on the face
should be fit-checked prior to
wearing in the work area.
a) Cover the front of the respirator
with both hands, being careful not to
disturb the position of respirator.
b) Inhale sharply. A negative
pressure should be felt inside
respirator. If any leakage is detected,
adjust position of respirator and/or
tension of strap. Retest the seal.
Repeat the procedure until the
respirator is sealed properly.
