Occupational Respirator Testing Expert Speaks Out

In June 2020, Schaefer wrote an open letter9 addressed to the chief medical officer in Alberta, Canada, Dr. Deena Hinshaw, pointing out the errors of recommending universal wearing of N95 masks, surgical masks or nonmedical masks as protection against SARS-CoV-2. In it, he writes:10

 

“I have been teaching and conducting respirator fit testing for over 20 years and now currently for my company SafeCom Training Services Inc. My clients include many government departments, our military, healthcare providers with Alberta Health Services, educational institutions and private industry. I am a published author and a recognized authority on this subject.

 

Filter respirator masks, especially N95, surgical and non-medical masks, provide negligible COVID-19 protection for the following reasons:

 

1.Viruses in the fluid envelopes that surround them can be very small, so small in fact that you would need an electron microscope to see them. N95 masks filter 95% of particles with a diameter of 0.3 microns or larger. COVID-19 particles are .08 – .12 microns.

 

2.Viruses don’t just enter us through our mouth and nose, but can also enter through our eyes and even the pores of our skin. The only effective barrier one can wear to protect against virus exposure would be a fully encapsulated hazmat suit with cuffs by ankles taped to boots and cuffs by wrists taped to gloves, while receiving breathing air from a self-contained breathing apparatus (SCBA).

 

This barrier is standard gear to protect against a biohazard (viruses) and would have to be worn in a possible virus hazard environment 24/7 and you wouldn’t be able to remove any part of it even to have a sip of water, eat or use the washroom while in the virus environment. If you did, you would become exposed and would negate all the prior precautions you had taken.”

 

Face Masks Pose Several Health Hazards

In his letter, and in the video above, Schaefer also stresses that these kinds of face masks pose “very real risks and possible serious threats to a wearer’s health” for a number of reasons, including the following:

 

1.Wearing a face mask increases breathing resistance, and since it makes both inhaling and exhaling more difficult, individuals with pre-existing medical conditions need to be screened by a medical professional to make sure they won’t be at risk of a medical emergency if wearing a face mask.

 

This includes those with shortness of breath, lung disease, panic attacks, breathing difficulties, chest pain on exertion, cardiovascular disease, fainting spells, claustrophobia, chronic bronchitis, heart problems, asthma, allergies, diabetes, seizures, high blood pressure and those with pacemakers. The impact of wearing a face mask during pregnancy is also wholly unknown.

 

2.Face masks can reduce oxygen intake, leading to potentially hazardous oxygen deficiency (hypoxia).

 

3.They also cause rapid accumulation of harmful carbon dioxide, which can have significant cognitive and physical impacts. That said, there is some evidence to support that this may be one of the few benefits of mask wearing, as slightly elevated CO2 levels can also contribute to health benefits as per my interview with Patrick McKeown. (We’re not talking about dangerously high levels, however.)

 

4.Wearing a face mask increases your body temperature and physical stress, which could result in an elevated temperature reading that is not related to infection.

 

5.All face masks can cause bacterial and fungal infections in the user as warm, moist air accumulates inside the mask. This is the perfect breeding ground for pathogens. “That is why N95 and other disposable masks were only designed to be short duration, specific task use and then immediately discarded,” Schaefer notes.

 

Medical doctors have warned that bacterial pneumonia, facial rashes, fungal infections on the face,11 “mask mouth” (symptoms of which include bad breath, tooth decay and gum inflammation) and candida mouth infections12 are all on the rise.

 

What’s worse, a study13,14 published in the February 2021 issue of the journal Cancer Discovery found that the presence of microbes in your lungs can worsen lung cancer pathogenesis and can contribute to advanced stage lung cancer. As reported by Global Research:15

 

“While analyzing lung microbes of 83 untreated adults with lung cancer, the research team discovered that colonies of Veillonella, Prevotella, and Streptococcus bacteria, which may be cultivated through prolonged mask wearing, are all found in larger quantities in patients with advanced stage lung cancer than in earlier stages.

 

The presence of these bacterial cultures is also associated with a lower chance of survival and increased tumor growth regardless of the stage.”

 

6.With extended use, medical masks will begin to break down and release chemicals that are then inhaled. Tiny microfibers are also released, which can cause health problems when inhaled. This hazard was highlighted in a performance study16 being published in the June 2021 issue of Journal of Hazardous Materials.

 

Schaefer also points out that to provide any benefit whatsoever, users must be fitted with the right type and size of respirator, and must undergo fit testing by a trained professional. However, N95 respirators, even when fitted properly, will not protect against viral exposures but can adequately protect against larger particles.

 

Surgical masks, which do not seal to your face, “do not filter anything,” Schaefer notes. These types of masks are designed to prevent bacteria from the mouth, nose and face from entering the patient during surgical procedures, and researchers have warned that contaminated surgical masks actually pose an infection risk.17 After just two hours, a significant increase in bacterial load on the mask was observed.

 

Nonmedical cloth masks are not only ineffective but also particularly dangerous as they’re not engineered for “easy inhalation and effective purging of exhaled carbon dioxide,” making them wholly unsuitable for use.

 

In the video, Schaefer demonstrates the only type of mask that is actually safe to wear — the gas mask kind of respirator you’d use to protect yourself against painting fumes, organic vapors, smoke and dust.

 

Real respirators are built to filter the air you breathe in, and get rid of the carbon dioxide and humidity from the air you breathe out, thereby ensuring there’s no dangerous buildup of carbon dioxide or reduction in oxygen inside the mask.
