FACE COVERINGS, MASKS, ESCAPE HOODS, RESPIRATORS AND SCBA

                      

Just what do we really need & what is best? Looking at the types available including the protection levels. Numerous links within this article bringing relevant information.
A sensible add to the kit are FFP3, the FFP3 is indeed stockpiled within the government pandemic preparedness strategy along with the surgical (type2) masks. If you are looking for a full face respirator i would recommend a visit to your nearest industrial safety store where you can try some on and ask a whole lot of questions. You do not have to buy a military mask, plenty of certified civilian models available made to the same very high exacting standards. A word on fitting, looking in the mirror and telling yourself you look hot is not a professional fit test, check link below and if you use them at work getting a qualified fit test is the law. As far as smoke risk in the home considerations should be made regarding a wall mounted smoke /escape hood

                 GENERAL FACE MASKS

                               GENERAL FACE MASKS
These should conform to EN149/2001. Available are FFP models 1, 2 and 3 (N95, 99 and 100) they give filtration of said particulate and liquid / droplets  at 80, 94 and 99% 
Below a selection of basic masks including dust, FFP 2/3 and a smog

Before you buy your FFP grade masks purchase a few single of different makes and try them to ensure you find the best fit before buying many.

SURGICAL MASKS

These must adhere to the standard 14683:2005 of which are two types, 1 giving a 95% filtration rate and Type 2 giving 98%  Surgical masks are stockpiled by government / NHS within it's pandemic preparedness strategy along with FFP3 (N99) masks ( neither of which will be for public release ) Surgical masks have different standards to the FFP variety but afford some protection when the correct procedure is followed within a situation not outweighing the masks tested safety and protection standards
