Name:   MAJ USA RET - Subject:   What about people who MUST wear masks? Date:   7/8/2020 9:27:18 AM (updated 7/8/2020 9:29:36 AM)

I was... year-after-year (1994 to retirement... required to maintain OSHA 1910.120 certification "Hazardous Waste Operator" at the Supervisor level.  10 CFR 1910.120 App B is the part of the federal regulation which deals with PPE (personal protection equipment).  Of special intent is to protect the wearer from substances based on "particle size."   https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.120AppB

The particle size of viruses ranges from .0016 to .01 microns.  In comparison, tobacco smoke is .013 to .19 microns.  Both of these fall in the "ultrafiltration" range.

To test our PPE masks, we were required to have a clear shaven face and the mask fitted and adjusted so that we could not smell smoke (if ultrafiltration). 

So... if you are concerned about corona virus put on your mask and have someone smoke a cigarette near you.  The question is: Can you smell the cigarette?

I refuse to be stampeded by the media, politicians, and various "experts."  Their messages are stressful, conflicted, confusing, inconsistent, and amorphous.  Remember this after the election in November.  Because the whole "virus message and behaviors" will change IMMEDIATELY after the election.
