Interim Domestic Guidance on the Use of Respirators to Prevent Transmission of SARS
May 3, 2005

Download PDF version formatted for print (126 KB/2 pages)

Health-care workers caring for patients with Severe Acute Respiratory Syndrome (SARS) are at risk for acquiring SARS. Although the infectivity of SARS is currently uncertain, transmission to health-care workers appears to have occurred after close contact with symptomatic individuals (e.g., persons with fever or respiratory symptoms), particularly before implementation of recommended infection control precautions for SARS (i.e., unprotected exposures). Personal protective equipment appropriate for standard, contact, and airborne precautions (e.g., hand hygiene, gown, gloves, and N95 respirators) in addition to eye protection, have been recommended for health-care workers to prevent transmission of SARS in health-care settings (see the Infection Control and Exposure Management page).

The transmission of SARS appears to occur predominantly by direct contact with infectious material, including dispersal of large respiratory droplets. However, it is also possible that SARS can be spread through the airborne route. Accordingly, CDC has recommended the use of N95 respirators, consistent with respiratory protection for airborne diseases, such as tuberculosis.

SARS, unlike tuberculosis, also appears to spread by direct contact with respiratory secretions, which makes touching contaminated objects a potential concern. Although reaerosolization of infectious material is unlikely under normal use conditions, infectious material deposited on a respirator may cause it to become a vehicle for direct or indirect transmission. Therefore, additional infection control measures applicable to this specific situation are needed.

This interim guidance provides information on the selection and handling of respirators for SARS and includes guidance for when respirators are either not available or in short supply.

A NIOSH-certified, disposable N95 respirator is sufficient for routine airborne isolation precautions. Use of a higher level of respiratory protection may be considered for certain aerosol-generating procedures (see Infection Control Precautions for Aerosol-Generating Procedures on Patients Who Have SARS).


Respirators should be used in the context of a complete respiratory protection program in accordance with OSHA regulations. This includes training and fit testing to ensure a proper seal between the respiratorís sealing surface and the wearerís face. Detailed information on respirator programs, including fit test procedures can be accessed at www.osha.gov/SLTC/etools/respiratory.


Once worn in the presence of a SARS patient, the respirator should be considered potentially contaminated with infectious material, and touching the outside of the device should be avoided. Upon leaving the patientís room, the disposable respirator should be removed and discarded, followed by hand hygiene.


If a sufficient supply of respirators is not available, healthcare facilities may consider reuse as long as the device has not been obviously soiled or damaged (e.g., creased or torn). Data on reuse of respirators for SARS are not available. Reuse may increase the potential for contamination; however, this risk must be balanced against the need to fully provide respiratory protection for healthcare personnel.

If N95 respirators are reused for contact with SARS patients, implement a procedure for safer reuse to prevent contamination through contact with infectious droplets on the outside of the respirator.


Consider wearing a loose-fitting barrier that does not interfere with fit or seal (e.g., surgical mask, face shield) over the respirator.


Remove the barrier upon leaving the patientís room and perform hand hygiene. Surgical masks should be discarded; face shields should be cleaned and disinfected.


Remove the respirator and either hang it in a designated area or place it in a bag. (Consider labeling respirators with a userís name before use to prevent reuse by another individual.)


Use care when placing a used respirator on the face to ensure proper fit for respiratory protection and to avoid contact with infectious material that may be present on the outside of the mask.


Perform hand hygiene after replacing the respirator on the face.


When elastomeric (rubber) or powered air purifying respirators (PAPRs) are used, their reusable elements should be cleaned and disinfected after use, in accordance with manufacturerís recommendations. When half- or full-facepiece elastomeric negative pressure respirators are used by more than one individual, filters should be replaced between individual users. When PAPRs are used, the filters should be replaced following manufacturerís recommendations. All used filters must be safely discarded.


Respiratory protective devices with a filter efficiency of 95% or greater (e.g., N95, N99, N100) may not be available in some settings due to supply shortages or other factors. In this situation, a surgical (procedure) mask should be worn. Surgical masks will provide barrier protection against large droplets that are considered to be the primary route of SARS transmission. However, surgical masks may not adequately protect against aerosol or airborne particles, primarily because they allow for leakage around the mask and cannot be fit tested. The mask should resist fluid penetration and fit tightly around the mouth and nose when properly applied to the face.


Hand hygiene is urged for all contact with suspect SARS patients or objects that may be contaminated with the virus that causes SARS, including hand washing with soap and water; if hands are not visibly soiled, alcohol-based hand rubs may be use as an alternative to hand washing.

If it prevents spit and snot from hitting me by a masked infected person, then its a good thing. If it prevents my spit and snot from hitting somebody else that's a good thing.

Thank you Trinity. I even heard this BS on the NBC nightly news. WTF ????

The N95 masks DO work... and even better to wear wrap-around goggles with them.

Of course latex gloves or hand sanitation should be incorporated if you have to go out.

If you bring home products, wipe them all off with a solution of bleach and water.

Don't forget how dirty money is... who's hands it's been in.

I tend to believe the science behind the particle size of the virus being smaller than the mask can filter out..

therefor making them ineffective

They need to weave silver thread into the mask. That way the mask would be self cleaning. Spraying it with Colloidal Silver and then letting it dry overnight might be better than nothing if you start to run out of masks or access to more disappears. The CS would kill anything on the mask and leave micro silver particles embedded in the mask to continue the anti-viral/anti-bacterial effect.

Its a probability. If you lessen the risk from certain things (i.e. spit snot) then that lessens the exposure risk to others. The odds go down. If you are wearing gloves the odds go down. If you wash, dont touch your face, etc... the odds go down. If you don't get sneezed on the odds go down.

Anything to make the odds go down is good.

Re: DISINFO pinned regarding N95 respirators !!! See CDC recommendations EVEN for SARS !!
This is the CURRENT recommendations for the current strain... from the CDC website:

Masks and respirators: Until additional, specific information is available regarding the behavior of this swine influenza A (H1N1), the guidance in the October 2006 "Interim Guidance on Planning for the Use of Surgical Masks and Respirators in Healthcare Settings during an Influenza Pandemic" [link to www.pandemicflu.gov] should be used. These interim recommendations will be updated as additional information becomes available.

Interim recommendations:

Personnel engaged in aerosol generating activities (e.g., collection of clinical specimens, endotracheal intubation, nebulizer treatment, bronchoscopy, and resuscitation involving emergency intubation or cardiac pulmonary resuscitation) for suspected or confirmed swine influenza A (H1N1) cases should wear a fit-tested disposable N95 respirator.*
Pending clarification of transmission patterns for this virus, personnel providing direct patient care for suspected or confirmed swine influenza A (H1N1) cases should wear a fit-tested disposable N95 respirator when entering the patient room.
*Respirator use should be in the context of a complete respiratory protection program in accordance with Occupational Safety and Health Administration (OSHA) regulations. Information on respiratory protection programs and fit test procedures can be accessed at www.osha.gov/SLTC/etools/respiratory. Staff should be medically cleared, fit-tested, and trained for respirator use, including: proper fit-testing and use of respirators, safe removal and disposal, and medical contraindications to respirator use.

I agree with the op. If you all are so confident about the BS posted on that other thread I suggest the next time you have surgery you tell all the docs,nurses in the room to not wear a mask.

Now the silly masks the Mexicans were/are wearing barely do anything but a well fitted N95 is something different all together.

N95 is good- get N100 if you want-I don't think they are that much more. BUT-make sure you learn how to fit them correctly...you can endanger yourself with a friggin spork or a circle of paper and poke your eye out with mittens if not used correctly

The virus can not survive and float around in the air without a transport medium. Saliva, mucus, water, or dust. The N95 when properly used, can stop you from inhaling these transport mediums. This mask offers protection for about 3 hours of constant use, then it must be replaced with a new one.
