RE: RSPA-98-3971 [HM-226]
April 18, 2001
Dear Sirs;
The American Biological Safety Association (ABSA) is
an international group of biological safety professionals which is known
as one of the world's foremost resources on biological safety practices.
We have reviewed the proposed rule, "Hazardous Materials: Revision to
Standards for Infectious substances and Genetically Modified
Microorganisms" which was published in the January 22, 2001 issue of
the Federal Register. We ask that the Research and Special Projects
Administration (RSPA) of the U.S. Department of Transportation (DOT) to
consider the following comments:
General Comments
The proposal demonstrates a good, workable
regulation in this area. It represents a credible effort to harmonize
these DOT requirements for the Untied States with the international
requirements. We are grateful for your citation of the ABSA web site
(http://www.absa.org) as a source of technical information about the risk
group criteria of the World Health Organization specifically used in the
proposal. Our office has received requests from shippers
regarding access to the risk group information on the ABSA web site since
your proposal was published.
171.15 - Infectious Substances Definition and
Incident Reporting
ABSA commends the move to harmonize the DOT
definition for infectious substances with the international definition.
This move will reduce the confusion that has been known to occur when
shipping these packages by air or when sent outside of the United States.
This is a real concern, given the international scale of clinical trials
and infectious disease investigations that are currently being conducted
on a national and international scale.
Under 171.15 and 171.16, there are standing
requirements for hazardous materials shippers to make oral and written
reports to the National Response Center in the event of transportation
releases or incidents. The emphasis placed in the proposal on making these
notifications for events involving infectious substances is supported by
ABSA. We encourage RSPA to work with the CDC in developing a form for
filing written reports of these events to all concerned agencies.
171.134 - Class 6, Division 6.2 - Definitions and
Exceptions
We propose to expand the definition of Division 6.2
(infectious substances) to include prion diseases. Prions are
proteinaceous infectious particles that lack nucleic acid and are not
currently covered under the definition of pathogen in 171.134. This would
include, for example, agents responsible for infectious diseases such as
Creutzfeld-Jacob Disease (CJD) in humans or Bovine Spongiform
Encephalopathy (BSE) in animals (cattle). We feel that the special risk
associated with these materials warrants their inclusion in Class 6,
Division 6.2.
172.102 - Special Provisions
The inclusion of special provisions A81 and A82 in
the Hazardous Materials Table is appropriate. This is a first step towards
harmonization with the international requirements of the International
Civil Aviation Organization (ICAO). To complete these steps, the
provisions should reference the ICAO changes in A81 that are effective
after June 30, 2001. Those changes expand the exemption to cover all body
fluids and not just blood and blood products. The changes also increase
the maximum allowable quantity in primary receptacles to 1000 milliliters
instead of the current 500 milliliters.
172.432 - Emergency Notifications
ABSA endorses the proposed inclusion of the new
Centers for Disease Control and Prevention toll free telephone number for
reporting spills and incidents of infectious substances. This move
streamlines reporting of these incidents and will enhance collection of
data for future considerations.
173.6 - Materials of Trade
The expansion of this exemption is good. However,
most items shipped under the materials of trade exemption need to be
shipped in original hazardous materials packaging or its equivalent.
Diagnostic specimens are packaged for the first time when they are
collected from the physician's office. Some minimal acceptable packaging
should be identified for transportation of specimens under this exemption.
This should include at minimum a leak resistant bag, absorbent, and either
a sealed fiberboard box or a cooler with a secured latch.
173.28 - Reuse of Packaging
ABSA recommends use of the word,
"disinfect" rather than the word "decontaminate" with
respect to managing packages in which there has been a leak of infectious
substances. The Occupational Safety and Health Administration's (OSHA)
Bloodborne Pathogens standard does use the word, "decontaminate"
in the same context. However, OSHA does require the materials used for
this activity to be tuberculocidal grade disinfectants. If RSPA wishes to
provide clear guidance on how to properly conduct this activity, then use
of the word, "disinfection" will suffice. We also endorse the
conditional exclusion of disinfection of secondary packaging when it is
not contaminated by infectious substances. This same change in terminology
should also be applied to Section 177.843 in which a vehicle needs to be
disinfected.
173.134 - Risk Groups
ABSA endorses the concept of the use of risk group
criteria as a means of classifying Division 6.2 infectious substances.
Although the use of risk groups is currently part of the ICAO Technical
Instructions, we are aware that the WHO does not recommend the use of
their risk group criteria for this purpose. RSPA is also comfortable with
the use of the risk group concept, since the use of the WHO risk groups
that are within the ICAO Technical Instructions is referenced in its
proposal. RSPA also allows shippers to prepare shipments as per the ICAO
Technical Instructions. The current use of the WHO risk group criteria is
therefore, to be supported, with the understanding that its use will be
under revision by the WHO.
RSPA states that it is planning to work with WHO and
CDC to assure that updated guidance for determining the risk groups for
specific materials are easily available. ABSA considers this interagency
communication essential to the success of the implementation of this NPR.
Unfortunately, the CDC has not published or released their support for a
U.S. based risk group classification. In 1993, WHO urged countries to
develop their own classification. However, CDC has yet to respond. For
that reason, ABSA would like to encourage RSPA to secure CDC support in
developing a risk group classification prior to implementation of the NPR.
Otherwise, the only U.S. based risk group classification currently
available, is based on the highly technical and research environment
specific "NIH Guidelines for Research involving Recombinant DNA
Molecules". These guidelines are also limited in their support for an
animal pathogen risk group classification. The current NIH guidelines
cover only those animal pathogens that may pose theoretical risks "if
inoculated" into humans. ABSA considers USDA to be an appropriate
agency to assist in or develop an animal pathogen based risk group
classification.
RSPA needs to be aware of the fact that although the
ABSA web site currently contains a listing of risk groups, this
information is largely based on international resources. With the
exception of the NIH guidelines, it lacks a comprehensive U.S. based risk
group classification. To reference risk groups from other countries as the
basis for shipping and transportation requirements inside the U.S. would
not be appropriate. In case CDC will not support and develop a U.S. based
risk group classification in a timely fashion, ABSA encourages RSPA to
officially cite and endorse the NIH guidelines (http://www4.od.nih.gov/oba/rac/guidelines/guidelines.html)
as a source for such information. Animal pathogens warrant special
consideration with respect to risk groups. Animal pathogens can adversely
affect public health directly and indirectly. Some countries, such as
Canada and Australia, have included animal pathogens in their shipping
regulations, whereas the current list of these agents in the applicable
publications of the CDC and the National Institutes of Health (NIH) is
rather short and limited. The criteria used by any given country can vary.
This variability points to the need for close coordination with RSPA and
CDC in the development of these criteria if consistent shipping decisions
regarding animal pathogens are to be made.
173.134(a)(8) Class 6, Division 6.2 -Definitions and
Exceptions - Toxins
Your definition of a toxin indicates that toxins are
secreted from a plant, animal, or bacterial source. For toxin
investigations, these materials may be removed from the organism. The use
of the word, "obtained" would be more appropriate.
173.140 - Genetically Modified Micro-organisms
ABSA agrees with RSPA's concern that
"genetically modified micro-organisms may impact the environment if a
shipping mishap were to occur". We recommend the recognition of
"genetically modified micro-organisms" as a transportation
concern and for establishing minimum acceptable packaging criteria under
Class 9. Genetically modified organisms can be of significant concern for
the public and the environment if an uncontrolled release occurs.
173.199 (b)(4) - Air Transportation of Infectious
Substances and Diagnostic Specimens
ABSA supports the requirement for the 95 kilopascal
pressure test as limited to air shipments of infectious substances or
diagnostic specimens. This is in keeping with ICAO/ International Air
Transport Association (IATA) requirements.
173.199 (d) - Used Health Care Products
ABSA supports RSPA's provision for exemption of
health care products under certain conditions. However, ABSA questions the
rationale for requiring special considerations for all "used health
care products." ABSA agrees that there are certain materials that
pose a potential hazard during transport, such as those involving
contaminated sharps or those still containing liquid blood. However, the
proposed definition of used health care products as used by RSPA refers to
almost everything in a hospital and laboratory environment from a bedpan
to a pacemaker, an automatic pipettor to a spectrophotometer, a blood
glucose monitor to a dialysis machine, etc. Is it really RSPA's intent to
regulate such items? ABSA encourages RSPA to provide clarification on this
issue. ABSA would like to suggest limiting the definition to those
products that have been used and are contaminated with potentially
infectious body fluids or materials as outlined by the OSHA Bloodborne
Pathogens Standard (29 CFR 1910.1030). In addition, RSPA should limit the
definition to those products where those hazards cannot be removed or
mitigated prior to transport through disinfection.
By limiting the products covered under the NPR, RSPA
clearly focuses on products that can contain potentially infectious
materials and therefore might pose a risk. In addition, packing
requirements for these products should be based on the actual risk. ABSA
supports the packaging requirements as outlined in the NPR for products
that have the potential of cutting or penetrating skin or packaging
material. However, the use of watertight plastic or metal containers for
both primary and secondary containers appears far too restrictive and is
not supported by any actual risk data. Packaging used for returned health
care products that only contain residues of dried body fluids (no liquids)
should meet certain performance criteria without being limited by the NPR.
Such criteria should include the provision of prohibiting the release of
the material during routine transport. This would allow the manufacturer
to design return packaging without the prohibitive restrictions currently
proposed by the NPR.
Section 177.834 - Securing of Shipments During
Transport
ABSA commends RSPA for including a requirement for
Division 6.2 materials to be secured in transport, thus averting potential
exposures to such materials and the clean-up and potential treatment of
personnel.
We thank you for the opportunity to review this
document, and your consideration of these comments.
Sincerely,
Debra Hunt, Dr.PH, RBP, CBSP (ABSA)
