I have heard various reasons why BC is not allowing HCWs to wear an N95 (or equivalent) while working at vaccine clinics.

But, I will submit to you that none of the arguments against N95s (or equivalents) are valid. See short thread ...

1/ Let's denote N95 (or equivalent eg. CAN-99, CN-95, KN94) = A

AND

ASTM3 surgical/medical mask = B

2/ In terms of respiratory protection (for both aerosols and droplets), A >> B.

So not allowing a HCW to wear A cannot be justified in terms of safety.

Some have used EQUITY as an excuse. If equity is an issue, then you empower all HCWs to have A.

3/ By using the equity argument, they are clearly acknowledging A > B.

Forcing HCWs to only choose B means you are putting all HCWs at risk.

4/ Let's imagine that A = B.
(For the droplet droplet dogma bitter enders who claim there is no RCT evidence demonstrating a difference).

In this scenario, there is also no justification for denying HCWs from choosing to wear A.

5/ But let's be irrational and suggest A << B.

If you want to use this argument then you need to to revise your understanding of basic physical concepts or show us evidence that A << B.

6/ So in summary, the current policy is irrational from both a scientific and logical position.

And I am taking no part in this madness. Thank you.
