Do you really know the difference between a mask and a respirator?
What is the difference between a mask and a respirator?
Primary purpose to prevent particles being expelled by the wearer into the environment.
Not necessarily designed to seal tightly to the face
Air leakage around the edges is likely.
Designed to reduce the wearer’s exposure to airborne particles.
Different classes offer different levels of protection.
FFP3 disposable respirators offer the highest level of protection available from this type of device.
When should I wear a respirator?
“When in an airborne state, micro-organisms can be classed as particles, so they should be removed by filter type RPE. You should always use equipment fitted with the highest efficiency filter possible (P3) to control exposure down to the lowest levels.”1
HSE, DH – recommend the use of FFP3 respirators for aerosol generating procedures, or where multi-drug resistant (MDR) TB is suspected or when aerosol generating procedures are carried out on a patient with pandemic influenza.
3M’s FFP3 or P3 respirators include 1863+, 3M 1873V+, 3M 8835, or the 3M 7500 fitted with 3M 6035 filters. More information can be found atwww.3m.co.uk/aura1800+
What is the difference between FFP 1, 2 and 3?
FFP3 or P3 is the most protective class of particulate disposable or reusable respirator
There is no such thing as a 100% efficient respirator
APF = The number of times exposure is reduced i.e. an FFP3 respirator reduces exposure by a factor of 20. For every 20 particles outside of the respirator 1 may get inside.
Assigned Protection Factor (APF)
What is Fit Testing and why does it matter?
Protection levels (APFs) will only be achieved if the respirator fits correctly on the face
Fit testing is a means of assessing how well a respirator seals to a face
It has to be an individual test because one model will never ‘fit all’ and every face is different.
To achieve a good fit:
Users MUST be clean shaven
Users must know how to fit it correctly
Users should be Face Fit Tested – a legal requirement for respirators with tight fitting face seals
3M Fit Testing Service
Full or half day qualitative or quantitative fit testing
