Cloth Masks Do Nothing To Stop The Spread of COVID -Listen to the experts in Industrial Hygiene.


Are our doctors, scientists, or public health officials “experts” in personal protective equipment (P.P.E.) masks? Many mistakenly think that they are. Read on, and I think what you are about to learn may surprise you. Stephen E. Petty is an expert in the field of Industrial Hygiene. You may ask, what is an Industrial Hygienist? Industrial Hygiene is the science and art devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stressors, including viruses, arising in or from the workplace, which may cause sickness, impaired health and wellbeing, or significant discomfort among workers or the citizens of the community.

Industrial Hygiene is fundamentally concerned with the proper methods of mitigating airborne/dermal hazards and pathogens and the design and use of engineering controls, administrative controls, and personal protective equipment (P.P.E.), among other things.


Medical doctors, virologists, immunologists, and many public health professionals ARE NOT qualified experts in these areas under the credentials mentioned above.


Mr. Petty has an impressive resume. He has testified about the futility and danger caused by an individual wearing a mask to avoid transmitting or becoming infected with Covid-19. Mr. Petty holds relevant industry certifications, including board certifications as a C.I.H. (Certified Industrial Hygienist), a C.S.P. (Certified Safety Professional), and as a P.E. (Professional Engineer) in six states (Florida, Kentucky, Ohio, Pennsylvania, Texas, and West Virginia).

Mr. Petty has also served as an expert in personal protective equipment and related disciplines in approximately 400 legal cases. He has often been certified as and provided testimony as an expert in these areas. He is currently serving as an expert in the Monsanto Roundup and 3-M PFAS litigation.

On May 7, 2021, the Centers for Disease Control (C.D.C.) updated its guidance, providing that the primary mechanism for transmission of Covid-19 is through airborne aerosols and not, as previously stated, by touching contaminated surfaces or through large respiratory droplets, as also noted during previous periods of the pandemic.


Airborne viral aerosols can consist of a single viral particle or multiple viral particles clumped together and usually smaller than five µ (microns) in size. By comparison, droplets are >5 µ to >10 µ in size.


A square micron is approximately 1/4000th of the cross-section area of a human hair and 1/88th the diameter of a human hair.


Covid particles are —1/10 of a micron or —1/40,000th the area of a cross-section of a human hair or —1/1,000th the diameter of a human hair.
