3. Personal protective equipment and procedures
The following PPE should be available for use by personnel providing direct care to the patient or with potential exposure to the patient’s body fluids, such as during cleaning:
Fit-tested, disposable respirators (at least as protective as fit-tested NIOSH-certified disposable N95 filtering face piece respirators), for use during aerosol-generating procedures if needed.

Excuse me all to HE*L - but why isn't that the definition of AIRBORNE?
Sounds good as long as you don’t inhale while breathing.
What’s to stop it from being drawn through while you’re breathing?
You also need a P100. N100 is not good for hydrocarbons and will break down, so if there are any airborne solvent particles you might have breakthrough. I have never seen an N100 in the field.
The filter media does not have holes 0.3 microns (Micrometers) in diameter. There are small bubbles connected by tinier passages, so particulates don’t take a straight path through the filter, but must take multiple turns. The filters are very dense. I am an industrial hygienist (since 1991). Not an expert though, so don’t ask me that in court LOL.
“Did they (CDC) mention how frequent you should replace the N95 masks?”
Generally, filters get better with use...
Technically a virus that is said to be airborne is one that stays viable all by itself (i.e., not on a particle or in a droplet of something else) in the air.
There is a lot of info on getting suited up etc.-but I haven’t seen/read anything on removing the exposed items. That makes a difference as well and I wonder if that could be a factor in some cases with suited-up medical staff/caretakers becoming infected; an error in removing a soiled glove or mask could expose one to the pathogen as well.
I have and still do have respect for the CDC, but it is the ‘heads’, who have appeared on TV etc.,that have left me wondering about and disappointed with their approach to a situation that they have (supposedly) trained for their entire career(s). They were the one govt related agency I thought-maybe naively-were ‘above politics’ when it came to a deadly bug that once brought here, kills anyone.
And THAT is the key-’brought here’...so to not do all they can to keep it out-like stopping people from entering who originated from Ebola countries-is just mind-boggling to us little folk...
“In the case of preparing for Ebola, keep in mind that the Ebola virus strands can be as small as .02 microns in diameter, which are smaller than 3 microns. That said, the virus can permeate the filtered masks by a carrier such as (water molecules, bodily fluids, etc.). The best bet in assuring your family’s safety against Ebola is with N100 or P100 mask. Further, investing in other pandemic supplies would also be worthwhile.”
Thank you for the good info. Just still trying to figure this out. Hence “Vanity” post.
Sneezing and coughing droplets by definition are airborne are they not? I sneeze, it goes into the air? Someone else breathes in my particles?
“N95 respirators made by different companies were found to have different filtration efficiencies for the most penetrating particle size (0.1 to 0.3 micron), but all were at least 95% efficient at that size. Above the most penetrating particle size the filtration efficiency increases with size; it reaches approximately 99.5% or higher at about 0.75 micron. Tests with bacteria of size and shape similar to Mycobacterium tuberculosis also showed filtration efficiencies of 99.5% or higher.”
From your link. The 3 micron figure makes no sense,the 0.3 figure makes sense.

Yeah that is the M85 mask.
I was meaning the N95. I will no longer post a Vanity when I’m tired. Just glad most Freepers figured out.
Just have a lot of questions, and trying to getting the correct information.

Spanish Ebola case: ‘I am due to treat the patient. But I have no idea what to do’
A doctor who will treat Maria Teresa Romero Ramos, the Spanish nurse who has contracted Ebola, has launched a scathing attack on his country's training procedures
By Fiona Govan, Madrid1:33PM BST 08 Oct 2014
http://www.telegraph.co.uk/news/worldnews/ebola/11148579/Spanish-Ebola-case-I-am-due-to-treat-the-patient.-But-I-have-no-idea-what-to-do.html?
A senior doctor at the Madrid hospital where the Spanish nurse infected with Ebola is being treated has warned that staff are not sufficiently trained to deal with the virus.
His warning comes as the sixth person in Spain was put into quarantine on Wednesday morning.
Dr Santiago Yus, a specialist in intensive care with more than 30 years experience at the hospital where the six isolated patients are being treated, claimed medics have received only minimal training.
“Tomorrow or the day after tomorrow I will be expected to treat the Ebola patient and nobody has even taught me to put on the protective suit,” he said in an interview with Spain's daily El Mundo newspaper.
“I am not ready, I am not trained. And it's the same with my colleagues.”
He said that he and other doctors had been given a ten-minute briefing on management of Ebola patients and shown some photographs on a wall. Two months ago they were given a demonstration on how to put on the protective suit.
“A doctor and a nurse put the suit on and took it off. The training was and is absolutely insufficient,” he said.
The warning will set off alarm bells as Spain's public health officials struggle to quell panic after a fourth nurse in Madrid – who like Maria Teresa Romero Ramos had cared for an infected Spanish missionary – was quarantined with suspected symptoms of the deadly Ebola virus.
In addition to the four nurses, Mrs Romero's husband is in quarantine, as is an engineer who returned to Spain from Nigeria.
Dr Yus is among fifteen health workers at the Carlos III hospital who have made a formal complaint to management about their lack of training in the face of the current crisis.
Mrs Romero was transferred to a specialist isolation unit at the Carlos III hospital on Monday night after testing positive for the haemorrhagic fever, becoming the first case of contracting Ebola virus outside West Africa.
It is still unclear how exactly she was infected with the virus while she was part of a team treating two missionaries repatriated from West Africa.
But sources close to the investigation into how the infection occurred have suggested Mrs Romero may not have followed proper procedure when removing her protective suit after coming into contact with the second Ebola patient.
Manuel Garcia Viejo, 69 died at the Madrid hospital on September 25, five days after being airlifted from Sierra Leone.
Miguel Pajares, 74, died there in August after his repatriation from Liberia.
0.3(N95 Mask) vs. 0.08(The current Ebola nano particle size)
Actually that’s the M17A2 military version. But I know the M85 you alluded to.
I get that-————the problem is with the 3 Micron claim.
3 Microns in the header,not 0.3 Microns. Big difference.
.
US military that is. I think M85 is Romanian but not sure about that.
Look the CDC has dropped the ball... I just don't think they know what they are doing?
