3M™ Particulate Respirators C300 Series
Description
The 3M™ Particulate Respirators C300 Series meet the requirements of European Standard
EN149:2001 + A1:2009, filtering facepiece respirators for use against particles. They provide
effective respiratory protection for use in industries where workers will be exposed to solid
(dust) particles and/or non-volatile liquid particles.
Applications
These respirators are suitable for use in concentrations of solid (dust) particles and/or non-volatile liquid particles up to the
following limits:
Product
C310
C312 (with valve)
C320
C322 (with valve)
*Many countries apply Assigned Protection Factors (APFs) which reduce the maximum concentrations of particles in which
these products can be used. See national regulations and EN 529:2005.
Respiratory protection is only effective if it is correctly selected, fitted and worn throughout the time when the wearer is
exposed to hazards.
Standards
Products are classified by filtering efficiency and maximum total inward leakage performance (FFP1, FFP2 and FFP3), also by
usability and clogging resistance. Performance tests in this standard include filter penetration; extended exposure (loading)
test; flammability; breathing resistance and total inward leakage. Reusable products are also subjected to cleaning, storage
and mandatory clogging resistance tests (clogging is optional for non-reusable products). A full copy of EN 149:2001+A1:2009
can be purchased from your national standards body.
Filter Penetration
The filter penetration, initial and after 120mg of loading with both 120mg of NaCl* and Paraffin Oil, shall not exceed the
following limits:
EN 149:2001+A1:2009 Classification
FFP1 NR D
FFP2 NR D

Total Inward Leakage Ten subjects perform five test exercises whilst wearing the respirator. The total inward leakage inside of the respirator due to face seal leakage, filter penetration and valve leakage is measured for each subject exercise.

Page 3: Storage And Transportation
Storage and Transportation 3M™ Particulate Respirators C300 Series have a shelf life of 3 years from date of manufacture. End of shelf life is marked on the product packaging and upon the product. Before initial use, always check that the product is within the stated shelf life (use-by-date). -
Page 4: Fitting Instructions
• These products do not protect against gases/vapours. • Do not use in atmospheres containing less than 19.5% oxygen. (3M definition. Individual countries may apply their own limits on oxygen deficiency. Seek advice if in doubt.) • Do not use for respiratory protection against atmospheric contaminants/concentrations which are unknown or imme- diately dangerous to life and health (IDLH). - Page 5 3M Personal Safety Division User Seal Check Cover the front of the respirator with both hands being careful not to disturb the fit of the respirator. UNVALVED respirator - EXHALE sharply; VALVED respirator - INHALE sharply; If air leaks around the nose, re-adjust the noseclip to eliminate leakage. Repeat the above user seal check.
