An N95 FFR is a type of disposable respirator where the filtration media is the respirator. The respirator forms a tight seal to the face and removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3-micron) particles. N95 FFRs are capable of filtering out particles, including bacteria, viruses, and dust.
Respirators are available in multiple size configurations and are not standardized across models. Fit testing is needed to determine if a particular size and model of respirator provides you with an acceptable fit. Before you wear a respirator in an occupational setting, you must be fit tested for each respirator model you will wear for your designated work tasks.
For more information, see the NIOSH fact sheet, Filtering out Confusion: Frequently Asked Questions about Respiratory Protection, Fit Testing.
Yes. OSHA regulations require that workplaces provide employees respirator training prior to use in the workplace. It is important that you know what respirator to use and how to use it correctly so that it can provide the expected protection. Refer to OSHA 29 CFR 1910.134external icon for more information.
For more information, see the NIOSH infographic, You’ve just completed your Annual Respirator Training pdf icon.
In most workplace situations, a filtering facepiece respirator (FFR) such as an N95 can be reused as part of an employer’s respiratory protection program. Limited reuse refers to the practice of using the same FFR multiple times during a work shift. The respirator is stored between uses and put on again (donned) prior to the next potential exposure for a limited number of donnings. Unless the manufacturer identifies a specified duration of use (for example, “single-use only”) or the employer’s respirator program excludes reuse (for example, when exposed to infectious agents capable of being transmitted by contact), users can wear an FFR until it is damaged, soiled, or causing noticeably increased breathing resistance. FFRs should only be reused by the same wearer and should be stored:
For more information, see the NIOSH fact sheet, Filtering out Confusion: Frequently Asked Questions about Respiratory Protection, Respirator Reuse and Extended Use.
Regardless of the setting, the number of times you can reuse an FFR should be limited. Consult the FFR manufacturer for specific guidance regarding reuse and storage of the product.
Obama finally “got it” that his red line and his hawkish posturing left him standing on the brink, alone. Hollande might jump off the cliff with him, but then again, he might not. US Ambassadors had fanned out to foreign capitals, but were being rebuffed — no one wanted to join a coalition of hubris. …
I discussed multiple topics, including: 1. markedly increased mortality rates seen in heavily vaccinated countries, 2. the coordinated rollout of new untested boosters throughout the EU, Switzerland, UK, Canada and the US on virtually the same day, 3. negative vaccine efficacy, 4. the poor vaccine efficacy that did not just start with omicron 5. regulatory…
https://www.newsweek.com/fauci-really-confident-people-recover-coronavirus-become-immune-infection-1494612 Dr. Anthony Fauci, the leading infectious disease expert on President Donald Trump’s coronavirus task force, said he was “really confident” that people who recover from the novel coronavirus gain immunity against reinfection. The National Institute of Allergy and Infectious Diseases (NIAID) director told Comedy Central’s The Daily Show with Trevor Noah on Thursday night that he…
COVID-19, a Second Opinion. Get educated. Best 5 hours you may ever spend. And it’s free. Senator Ron Johnson hosted a panel discussion yesterday, January 24, on all things COVID. It was amazing. All the experts from yesterday’s rally, and more, were present in one Senate room, and everyone had a chance to speak. Okay,…
I am posting this because FDA and CDC soon plan to license and impose de facto mandates of the vaccine for the 12-15 year age group, despite its danger for them. As the Los Angeles school district did 3 days ago. Myocarditis occurs at least 32 times more often than it should during the first…
Bloggers Larisa Alexandrovna (Raw Story.com) and Glenn Greenwald (Salon.com) beat the major press on Jean Duley’s background. Seems she has an extensive police record including two arrests for DUI since 2006 and a remote drug paraphernalia charge. I suspected as much, having read that she was involved in treating addicts with Suboxone. Many substance abuse…

I have been saying that for the last 2 years and counting!!!!!! A mask is a medical device, not a fashion accessory.
