Who is Stephen petty?
Stephen Petty, PE, CIH, CSP, host of the Petty Podcast and owner of EES Group in Pompano Beach - Florida, will be applying his knowledge as an engineer and health & safety expert to breakdown recent events (i.e. COVID-19, Surfside condo collapse, etc.) to better explain elements of these events and offer science-backed, common sense solutions.
Does your mask fit OSHA’s criteria for respiratory protection?
“There isn’t a single criteria that I find of the main criteria under the Respiratory Protection Standard [OSHA 29 CRF 1910.134] where mask fits their criteria.” (12:16) Petty. “IF [OSHA] ever admit that the primary mechanism of exposure is aerosols [as opposed to droplets] the mask and the six foot rule are dead.” (13:00) Petty
Are face masks really protective?
Despite telling the public to wear masks, OSHA admits they are not protective: The CDC also tells the public to wear masks, but also admits they are not protective: In other words, masks don’t meet any of the OSHA respiratory protection standards that are used in the workplace.
What is the potential discomfort of masks?
potential discomfort; a false sense of security, leading to potentially lower adherence to other critical preventive measures such as physical distancing and hand hygiene; poor compliance with mask wearing, in particular by young children;
How long does it take for a particle to drop from the mouth to the floor?
These particles, which infect people through inhalation into the lungs, are so small, that when exhaled into an indoor room, it will take hours, and most likely days, to drop the five feet from one’s mouth to the floor.
Do masks protect you?
So we know that with aerosols, masks do not protect you, or others.
Is a mask considered PPE?
Masks are not PPE. Scientific evidence suggests COVID-19 particles are mostly small aerosols – not droplets, which would mean respirators, rather than masks, are needed to protect the lungs (which makes the 6′ rule effectively meaningless).
Can masks cause self contamination?
potential increased risk of self-contamination due to the manipulation of a face mask and subsequently touching eyes with contaminated hands; potential self-contamination that can occur if non- medical masks are not changed when wet or soiled. This can create favourable conditions for microorganism to amplify;
Is OSHA protective of masks?
Despite telling the public to wear masks, OSHA admits they are not protective: The CDC also tells the public to wear masks, but also admits they are not protective: In other words, masks don’t meet any of the OSHA respiratory protection standards that are used in the workplace. Yet we’re being forcibly subjected to them, as are our children.
Do masks stop aerosols?
In other words, masks aren’t going to be able to stop the aerosol spread of the virus, but we want you to continue wearing masks, because they will stop “trapped” particles in larger droplets, i.e., close-range spitting in each other’s mouths.
