of the Centers for Disease Control and Prevention (CDC) Announcement
Opportunity for Businesses To Partner With National Institute for
Occupational Safety and Health (NIOSH) on a Research Project To
Evaluate the Reusability of Disposable Filtering Facepiece Respirators
(FFR) Used for Protection Against Infectious Aerosols
Authority: 29 U.S.C. Sections 651 et seq.
AGENCY: The National Institute for Occupational Safety and Health
(NIOSH), Centers for Disease Control and Prevention (CDC).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The National Personal Protective Technology Laboratory
(NPPTL), NIOSH, is conducting research to determine the reusability of
filtering facepiece respirators (FFR) exposed to infectious aerosols.
One aim of this research is to address whether NIOSH-certified FFR are
suitable for reuse after decontamination. NIOSH proposes to study the
effects of decontaminating a diverse array of FFR including NIOSH-
certified N95, P100, and N95 filtering facepiece respirator/surgical
mask. This project will also study the survivability of a simulant
influenza virus on FFR. NIOSH plans to include in the research study
some of the respirator models that have been stockpiled by the U.S
government to be used in the event of an influenza pandemic. NIOSH also
plans to include models that have head straps versus those that do not
have head straps, as well as models with and without exhalation valves.
Through this announcement, NIOSH is seeking to identify FFR
products or prototypes that possess anti-viral or other novel
technologies that disinfect or sterilize infectious aerosols (e.g.,
viruses) as part of their materials of construction. Program funding
constraints may limit the number of candidate respirators that may be
included in the research program. NIOSH will give consideration to the
incorporation of novel anti-viral technologies into this research study
using the following hierarchy for selection of candidate FFR products
and prototypes: (1) The FFR proposed for consideration in this study
are commercially available and are currently certified to meeting 42
CFR part 84 requirements, (2) the FFR proposed for consideration is in
the process of being certified by NIOSH to meet 42 CFR part 84
requirements, (3) the FFR proposed for consideration are either a
prototype or a commercially available product that has not been
submitted to NIOSH for certification and the manufacturer submitting
the letter of interest has received NIOSH certification for other
respiratory protection products, and (4) the FFR prototype contains a
unique technology for disinfecting or sterilizing infectious aerosol
particles trapped on the exterior surface of the FFR and complements
the diversity of technologies already considered in the research
design.
Candidate companies will be evaluated based on their capability to
achieve the identified criteria in sufficient quantities for testing.
Candidates selected could be requested to enter into a Cooperative
Research and Development Agreement (CRADA). This announcement does not
obligate NIOSH to enter into a contractual agreement with any
respondents. NIOSH reserves the right to establish a partnership based
on scientific analysis and capabilities found by way of this
announcement or other searches, if determined to be in the best
interest of the government.
DATES: Submit letters of interest within 30 days after the date of
publication of this notice in the Federal Register.
ADDRESSES: Interested manufacturers should submit a letter of interest
with information about their capabilities to: NIOSH, National Personal
Protection Technology Laboratory, P.O. Box 18070, 626 Cochrans Mill
Road, Attn: Jonathan Szalajda, Pittsburgh, PA 15236, E-mail address:

SUPPLEMENTARY INFORMATION: CDC recommends the use of disposable N95,
N99, or N100 filtering facepiece particulate respirators (FFR) as the
minimum level of respiratory protection against transmission of
influenza virus. During a respirator shortage, it is important to
consider whether a previously worn FFR can be used again. Reuse
guidelines in the NIOSH Guide to the Selection and Use of Particulate
Respirators Certified under 42 CFR 84 recommend reuse based on loading
of the filter and functioning of the respirator. Hospital settings tend
to have relatively low concentrations of particulates, but the
potential for infectious agents exists. Thus, reuse is more dependent
upon infection control procedures than on respirator loading
considerations. Respirators exposed to viruses are considered to be
potentially harmful because of the possibility for the respirator to
act as a fomite and the potential for the viral particle to become
dislodged during a sneeze/cough or from rough handling. Thus,
respirators worn in the presence of a potentially infected patient or
co-worker should be disposed of as infectious waste, and touching of
the outside of the respirator should be avoided.
In January, 2006, the Department of Health and Human Services asked
the Institute of Medicine (IOM) to convene a committee to conduct an
assessment of measures that can be taken that would permit the reuse of
disposable N95 particulate filtering respirators in healthcare settings
and to report the status of current knowledge about the need and
development of reusable N95 respirators for healthcare providers and
the general public. Some of the key recommendations from that study
were that research studies should be conducted to (1) understand the
efficacy of simple decontamination methods that could be used without
negative effects on respirator integrity; and (2) understand the risks
associated with handling a respirator that has been used for protection
against a viral threat (e.g., study the likelihood that the exterior
surface of the respirator might harbor pathogenic microorganisms and
thus serve as a fomite).
This research project addresses the major research gaps related to
the reusability of filtering facepiece respirators (FFR) during an
influenza pandemic. NIOSH/NPPTL plans to conduct a variety of tasks in
this research project, including: (1) Determining the effect of
decontamination on FFR filtration

performance; (2) Development of a standardized test protocol for
measuring the efficacy of a decontamination procedure for FFR; (3)
Measure the survivability of a virus simulant trapped on FFR; (4)
Measurement of the reaerosolization of a trapped virus simulant on FFR;
(5) Assess the efficacy of various decontamination methods suitable for
FFR; (6) Determine the effects of decontamination on the FFR fit; and
(7) produce a final report that could be used to issue guidance
documents on FFR reuse.
