Purpose
EN 149:2001+A1:2009 covers FFP1/FFP2/FFP3 performance classes for filtering half masks against particles; it is not a gas/vapour filter standard.

Filtering Half Mask Standard
EN 149:2001+A1:2009 covers FFP1/FFP2/FFP3 performance classes for filtering half masks against particles; it is not a gas/vapour filter standard.

02
Typical use
Tasks with dust/particle exposure where risk assessment requires suitable respiratory protection.
03
What to look for?
Check EN 149, FFP class and NR/R/D markings; select protection based on exposure assessment and face fit/seal.
CLASSES & SELECTION LOGIC
Technical classes in this standard
A class code is not a selection decision by itself. Interpret it together with task-specific risk assessment and manufacturer data.
FFP1
FFP1
Lower particle-protection class within EN 149.
FFP2
FFP2
Intermediate particle-protection class within EN 149.
FFP3
FFP3
Highest particle-protection class within EN 149.
SELECTION NOTE
FFP1, FFP2 and FFP3 are particle-protection classes. Selection must consider exposure level, face seal/fit and manufacturer instructions.
CRITICAL NOTE
EN 149 addresses particles; gas and vapour hazards require a separately selected suitable filter/respirator system.

READ THE PRODUCT IN THE FIELD
Where is the standard marking found?
Location varies by manufacturer and design. These are the first places to check; final verification must use the actual product and manufacturer documentation.
1
EN 149, FFP and NR/R/D marking printed on the mask body
The marking should be legible, durable and match the product.
2
Standard/edition, class and use markings on packaging
The marking should be legible, durable and match the product.
3
Manufacturer, model and conformity markings
The marking should be legible, durable and match the product.
STANDARD FAMILY
Standards often reviewed together
EN 149:2001+A1:2009Filtering half masks against particles; still the current published edition
EN 143Replaceable particle filters are used in different respirator systems
EN 14387Gas/vapour filters address different hazards
COMMONLY CONFUSED
They are not the same thing
FFP3 ≠ gas/vapour filter
FFP class is for particles; gas/vapour hazards such as solvent vapour require a suitable respirator/filter system.
WRONG-SELECTION EXAMPLE
A typical field mistake
Choosing an FFP3 mask for solvent vapour because it is the “highest level”.
Why is this a problem?
EN 149 FFP classes address particle hazards.
Better approach
Identify whether the hazard is particle or gas/vapour and verify the suitable respirator, filter and face-fit/seal requirements.

HSE FIELD CHECK
30-second field check
Use for quick pre-checks. It does not replace certification, competent inspection or task-specific risk assessment.
CHECK FOCUS
Is the hazard actually particulate and was the correct FFP class selected?
CRITICAL MISTAKE
Choosing an FFP3 mask for solvent vapour because it is the “highest level”.
BETTER APPROACH
Identify whether the hazard is particle or gas/vapour and verify the suitable respirator, filter and face-fit/seal requirements.
1
Is the hazard actually particulate and was the correct FFP class selected?
2
Does the mask fit correctly and meet face-seal/fit requirements?
3
Do facial hair, face shape or other PPE compromise the seal?
4
Are FFP and NR/R/D markings legible?
5
Is the mask dirty, damaged, damp or beyond its use limit?
