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].

Drying conditions return in Alberta, crews see more intense fire activity

As more wildfire evacuees are being allowed to return home in Alberta, provincial officials warn that warm, dry conditions are returning this weekend in some areas.
Melissa Story with Alberta Wildfire says the elevated fire conditions were anticipated and that crews on the ground are seeing more intense fire activity on the perimeters of wildfires.
But she says most fires haven’t grown substantially and she doesn’t believe any have jumped their containment lines.
The number of evacuees as of Saturday afternoon stood at 5,257, down from over 7,200 on Wednesday, following cooler and wetter conditions in the last week.
Nearly 50 wildfires in Alberta’s forest protection area are burning, with 14 of those listed as out-of-control.
Cyndee Evans, executive director of the Alberta Emergency Management Agency, says the situation remains serious despite recent positive news.
“While we can take heart that more Albertans are starting to return home, we cannot afford to drop our guard. Now is not the time for complacency. Please continue to do your part and help prevent the spread of wildfires and further damage from occurring,” Evans told a news conference Saturday.
Story noted that showers were forecast for some parts of Alberta later Saturday, reducing fire danger, but also cautioned they bring the risk of lightning.
Federal Emergency Preparedness Minister Bill Blair said in a tweet Saturday that an extension for the deployment of Canadian Armed Forces personnel to assist in firefighting efforts has been approved.
Story said firefighters from New Zealand were welcomed to the province Friday and that nearly 200 firefighters and support staff from Australia would be arriving this weekend.
Alberta remains under a provincewide state of emergency, although some bans on fires, ATVs and off-highway vehicles have been relaxed in recent days.
Parkland County west of Edmonton lifted a state of local emergency on Friday that had been in place since April 29, and downgraded a fire ban to a fire restriction. It said that meant “safe fires in approved fire pits with a screen are allowed and do not require a permit.”
Fires without screens still required permits, however, and open fires in the county are still banned.
The High Level Forest Area wildfire update noted the Pasqua fire located in the community of Fox Lake saw an increase in fire activity after warm and dry weather on Friday, and that temperatures and fire behaviour was expected to pick up on Saturday.
Fox Lake remains evacuated, but residents are being permitted to sign up for tours of the community on Monday to view damage. A statement from the Little Red River Cree Nation said priority will be given to people who have lost their homes.
“Tours will be visual only, as it is still not safe for members to walk around the community or house sites due to hot spots as well as possible toxins and hazards in the areas that have been burned,” said a statement posted online by the First Nation on Friday.

United Conservative leader Danielle Smith says she would aim to lower the level of political polarization in Alberta if her party wins what has been a tight and often bitter election race.
She made her remarks during her last news conference before Albertans go to the polls on Monday.
Smith says she would consult broadly and make decisions based on what she’s heard.
She adds her door is always open to people from all backgrounds and all political persuasions, and she would learn by exchanging ideas.
The UCP leader also says she was delighted to garner endorsements from former prime minister Stephen Harper and federal Conservative Opposition Leader Pierre Poilievre.
The rival New Democrats have been endorsed by high-profile former Calgary mayor Naheed Nenshi.
