At this time it is hoped that this will help summarise the masks to be worn in different situations when dealing with suspected or confirmed cases of Influenza. Any new or updated evidence that is presented may impact on this guidance and as such it will be updated appropriately.
"Use of FFP3 filtering masks (98% filtering efficiency) conforming to EN 149:2001 for persons entering the room. Care should be given to face-fit checking and face-fit testing for this equipment.
In the UK, COSHH (and other) Regulations require that PPE shall comply with the Personal Protective Equipment Regulations (2002). Simply, this means PPE shall be "CE" marked, i.e. confirm to the European PPE Directive (89/686/EEC).
Conformity is usually met by compliance to the European (EN) standard e.g. EN 149.RPE which conforms to the USA N95 classification will offer similar respiratory protection to an FFP2 respirator (92% filtering efficiency) but will not be "CE" marked and therefore should not be used".
