NIOSH Issues User Advisory Notice for Four
Champak N95 Respirators
The National Institute for Occupational Safety and Health (NIOSH) has issued a
user advisory notice for NIOSH-certified N95 respirators with the following
approval numbers: TC-84A-4363, TC-84A-4364, TC-84A-4394 and TC-84A-4665,
produced by Champak Enterprise Co., Ltd before February 2010 may, in limited
situations, not meet the filtration efficiency requirements specified in Title
42, Code of Federal Regulations, Part 84 due to faults in internal testing
procedures. Please discontinue use of these products until further notice.

For public and hospital use, many have suggested N-95 respirators. The IAFF does
not believe that this type of respirator will afford fire fighter and emergency
medical personnel proper protection. Accordingly, the IAFF recommends that
emergency responders use, at a minimum, a P-100 respirator.
The IAFF’s P-100 filter efficiency recommendation is consistent with
NIOSH
recommendations for emergency response to biological agent incidents:
Additionally the IAFF's recommendation is consistent with federal OSHA
regulations that state “where workers are exposed to a hazard that would require
the use of a respirator with HEPA filtration, the appropriate class of
respirator under the 42 CFR Part 84 certification is the Type 100 (N-100, R-100,
or P- 100).” The IAFF recommendation is also consistent with the specifications
contained in the World Health Organization’s Hospital Infection Control Guidance
for SARS.
Additionally, disposable respirators must have seal enhancing elastomeric
components (e.g. rubber or plastic respirator to face seals) and must be
equipped with two or more adjustable suspension straps. The IAFF believes, and
research has demonstrated, that without these components it is difficult, if not
impossible, to obtain and maintain a seal in the workplace. All disposable
respirators, as well as APRs and PAPRs, must also be certified by the National
Institute for Occupational Safety and Health (NIOSH). NIOSH-approved disposable
respirators are marked with the manufacturer’s name, the part number (P/N), the
level of protection provided by the filter (e.g., P-100), and “NIOSH.” This
information is printed on the facepiece, exhalation valve cover, or head straps.
If a NIOSH marking is not on the respirator, it is not certified by NIOSH and
should not be used. |
