Open Letter to Physicians and the Public of Alberta
Dear Dr. Hinshaw,
Re: Alberta Health recommendation that Albertans wear N95, surgical or non-medical masks in public to reduce the likelihood of transmitting or developing a condition from the coronavirus known as COVID-19
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:
- 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.
- 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.
3. Not only are N95, surgical and non-medical masks useless as protection from COVID-19, but in addition, they also create very real risks and possible serious threats to a wearer’s health for the following reasons
A. Wearing these masks increases breathing resistance, making it more difficult to both inhale and exhale. According to our Alberta government regulations on respirator (mask) use, anyone that is required to wear a respirator mask should be screened to determine their ability to safely wear one.
Any covering of the mouth and nose increases breathing resistance, whether the mask is certified or not. Those individuals with pre-existing medical conditions of shortness of breath, lung disease, panic attacks, breathing difficulties, chest pain in exertion, cardiovascular disease, fainting spells, claustrophobia, chronic bronchitis, heart problems, asthma, allergies, diabetes, seizures, high blood pressure and pacemakers need to be pre-screened by a medical professional to be approved to be able to safely wear one. Wearing these masks could cause a medical emergency for anyone with any of these conditions.
Pregnancy-related high blood pressure is possible. More research is necessary to determine the impact of wearing a mask for extended periods of time on pregnancy.
It is dangerous to recommend, much less mandate anyone with medical conditions to wear a mask without educating them about the risks involved in wearing them without having been pre-screened and approved by a medical professional first.
B. In order for any respirator mask to offer protection to a specific user, that user must be individually fitted with the right type, right size, if male – face must be clean shaven (only short moustache allowed). Next, the user must be fit tested with that respirator by a trained professional to determine whether or not the respirator is providing the user with an air- tight seal – a requirement for any respirator mask.
C. N95 masks – N for not resistant to oil particles, 95 for the percentage of protection – the lowest level of all respirator masks.
These masks even when properly sized and fitted will not protect against virus exposure, however they are capable of adequate protection from larger particles such as pet dander, pollen and sawdust.
Surgical masks (the paper ones that loop around the ears) – do not seal to the face and do not filter anything.
Nonmedical and/or homemade masks are dangerous because:
- ● Not engineered for the efficient yet protective requirements of easy inhalation and effective purging of exhaled carbon dioxide
- ● Could cause an oxygen deficiency for the user
- ● Could cause an accumulation of carbon dioxide for the user
- ● Shouldn’t be recommended under any circumstance
D. They increase body temperature and physical stress – could cause a high temperature alert on a thermometer gun
E. They impede verbal communication
F. N95, surgical and nonmedical masks can create infections and possible disease all by themselves by causing exhaled warm, moist air to accumulate on the inside material of the mask, right in front of the user’s mouth and nose, which is the perfect environment for bacteria to form, grow and multiply. That is why N95 and other disposable masks were only designed to be short duration, specific task use and then immediately discarded.
So if masks are not effective in preventing illness, what is? How about the age-old tried, tested and proven method of protecting our health with a healthy diet, clean water, avoidance of processed, junk and fast foods, plenty of fresh air, sunshine, moderate exercise, adequate restful sleep and avoidance of stress?
We all have an immune system that can fight and overcome any COVID-19 threat if it is healthy and we nurture it.
Thank you for reading this open letter and letting me share my expertise. I ask that you share this with the public via media statement as we are all committed to promoting good health for all Albertans. If you or any of the public wish to contact me with a question or comment, I would love to hear from you. I can best be reached [email protected]

Alberta premier to outline more support for business during COVID health restrictions
EDMONTON — Alberta Premier Jason Kenney is to speak this morning on providing more support to businesses during the COVID-19 pandemic.
Kenney promised more aid last week after his government introduced a new round of restrictions to reduce the spread of the novel coronavirus.
Retailers are limited to 15 per cent customer capacity and restaurants can only offer takeout or curbside service, although patios remain open.
The Opposition NDP says Kenney’s government has failed for a year to properly manage economic supports, saying the money is always too little, too late.
Kenney faces opposition from some quarters — even within his own caucus — to ease up on public-health measures even as the province is recording more than 1,000 new COVID-19 cases a day.
He says restrictions on public gatherings need to be in place a bit longer until vaccination rates reach critical mass.

Positive COVID-19 tests at world men's curling championship deemed “false positives”
CALGARY — The four positive COVID-19 tests that interrupted the men’s world curling championship are considered “false positives” from potentially contaminated samples, according to the World Curling Federation.
The men’s championship concluded late Sunday night with Sweden’s Niklas Edin winning a record fifth world men’s title.
No games were played Saturday because four participants, including one from a playoff team, tested positive for the virus in “exit” tests before leaving Calgary’s curling bubble.
None had symptoms of the illness.
All have tested negative in multiple re-tests since then, the WCF said Monday in a statement. All tests were conducted via PCR throat swabs.
“According to Alberta Health, PCR testing remains the gold standard for COVID-19 testing,” the WCF said. “Very rarely, there are occurrences through sampling or testing processes when samples may become contaminated and a false positive may result.
“Following an investigation over the weekend, it appears that this may have occurred in this case and follow-up testing was undertaken.”
All athletes and personnel considered close contacts of the four underwent testing Saturday with all results negative.
Every playoff team member was tested before and after each game Sunday with those results also negative, the WCF said. Hotel staff were also tested Sunday and cleared.
“With the original four positive test results now deemed as false positives, the integrity of the Calgary bubble remains intact,” the WCF declared.
“The change also allows international athletes who were considered close contacts, and who would have had to remain in isolation in Calgary for 14 days, will now be able to depart Calgary.”
The fifth of seven events in Calgary’s curling hub, the Humpty’s Champions Cup, gets underway Thursday.
