DEPARTMENT OF TRANSPORTATION
National Highway Traffic Safety Administration
49 CFR Part 571
Denial of Petition for Rulemaking; Federal Motor Vehicle Safety
Standards
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation.
ACTION: Denial of petition for rulemaking.
-----------------------------------------------------------------------
SUMMARY: This document denies Mr. Herb Denenberg's petition requesting
three agency rulemaking actions relating to carbon monoxide detection
in motor vehicles. In addition, Mr. Denenberg requested that
information regarding the availability of carbon monoxide detectors be
published in the agency's press releases and consumer advisories. The
petition requested that the agency take action on one or more of these
actions.
FOR FURTHER INFORMATION CONTACT: Mr. Chris Flanigan, Office of Safety
Performance Standards, NHTSA, 400 Seventh Street, SW, Washington, DC
20590. Mr. Flanigan's telephone number is: (202) 366-4918. His
facsimile number is (202) 366-4329.
SUPPLEMENTARY INFORMATION: By letter received by the agency on March
13, 1997, Mr. Denenberg requested that: (1) Carbon monoxide detectors
be required in all motor vehicles, (2) manufacturers be required to
offer them as an option in all motor vehicles, and (3) manufacturers be
required to include material in owner's manuals indicating the
availability and value of installing a carbon monoxide detector. In
addition, Mr. Denenberg requested that information regarding the
availability of carbon monoxide detectors be published in the agency's
press releases and consumer advisories. The petitioner asked that the
agency take action on one or more of these four requests.
Agency Analysis
To establish a new vehicle safety specification, the agency must
decide on the basis of data and analyses, that there is a significant
safety problem and that the safety problem would likely be reduced by
adopting that specification. To support his requests, the petitioner
cites data from NHTSA's Consumer Advisory of December 16, 1996. These
data (from a National Center for Health Statistics study) showed 353
fatalities occurred in 1993 as a result of accidental carbon monoxide
poisoning.
[[Page 49191]]
The petitioner states that ``many if not most of these deaths could be
prevented by carbon monoxide detectors'' installed in the vehicles. The
petitioner did not offer any data to support this assertion.
Of the 353 fatalities, the largest portion, 35 percent, occurred in
the winter months. In the spring and fall months, which can also be
cold in some parts of the country, 52 percent of the fatalities
occurred. Only 13 percent of the fatalities occurred in the summer
months. Further, in information obtained from the Center for Disease
Control, in the years 1979 through 1992, the fatality rate (fatalities
per state population per 100,000 people) for carbon monoxide deaths in
stationary vehicles is highest in the northern half of the country
(with fatality rates ranging from 0.29 to 0.72 in most of these
states). These rates drop (to between 0.00 and 0.16) in the southern
half of the country.
We believe the majority of these fatalities occur in cold weather
for two reasons. First, in cold weather, people may let their vehicles
warm up in a garage or enclosed area to keep themselves warm. This
could allow carbon monoxide to build up in these areas to fatal or
injurious levels. Second, if the area around a vehicle has not been
adequately cleared of snow, it could block the exhaust pipe. This could
cause carbon monoxide to build up inside the vehicle and create a
hazardous situation.
The first request Mr. Denenberg made was that the agency require
carbon monoxide detectors in all vehicles. As stated above, we believe
carbon monoxide poisoning to be primarily a cold weather problem. For
this reason, we do not think it is justifiable to require that all
vehicles be equipped with these detectors. A large portion of the
vehicles sold in this country will rarely, if ever, be driven in cold
weather. If one assumes that 15 million vehicles are manufactured in
the country each year, the total cost to the industry to equip all
vehicles with a detector would be substantially more than $240 million.
This is based on the estimate of $16 per detector obtained by the
petitioner from the Quantum Group, a manufacturer of carbon monoxide
detectors. According to the petitioner, the Quantum Group currently
sells this type of detector for between $35 and $60, but it estimated a
cost of $16 per detector based on the increase in production that would
result from them being required on all vehicles. This cost does not
include manufacturer installation and other costs such as manufacturer
and dealer profits. The agency has found in the past that these costs
generally add about 50 percent onto the original equipment cost. These
additional factors would raise the initial cost to the consumer
considerably, and, for a problem which would mainly affect vehicles
operating in cold climates, the agency cannot justify imposing this
cost burden on the industry and consumers.
An additional consumer cost that must be considered is the lifetime
maintenance of the detectors. With these detectors, the sensors need to
be replaced approximately every six years. This replacement should be
done by experienced personnel, so the detectors would most likely have
to be returned to the manufacturer for such work. Not only would this
increase the cost of the requirement, but it would reduce the
effectiveness in averting deaths. Some vehicle owners will undoubtedly
fail to maintain the detectors properly and will end up with inoperable
or otherwise less-than-effective detectors. Because the recommended
maintenance on these detectors should be done every six years, only the
six newest model years in the national fleet would be assured of having
fully effective detectors.
Another factor which leads the agency to believe that a detector
requirement would not be effective is the age of the vehicles involved
in carbon monoxide fatalities. Many of these fatalities were caused by
degradation of the vehicle's interior and/or exhaust system which
allowed exhaust gases to enter the passenger compartment. We believe it
fair to assume that, of the vehicles which have developed this type of
degradation, most will be more than six years old. As stated
previously, only the six newest model years in the national fleet would
be assured of having fully-effective detectors. Under this assumption,
by the time vehicles begin to exhibit this type of degradation, the
carbon monoxide detectors may be in need of scheduled maintenance.
Mr. Denenberg's second request was to require manufacturers to
offer these detectors as an option on all vehicles. As previously
stated, the agency believes that it would not be cost-effective to
require carbon monoxide detectors in vehicles. For the same reason, we
do not believe manufacturers should be required to offer them as an
option. To require them to be offered as an option would also be costly
to the industry, as vehicles would have to be redesigned to incorporate
the detectors. Further, if vehicle owners wish to place a detector in
their vehicles, they are not precluded from doing so.
Regarding Mr. Denenberg's request that information on these
detectors be placed in owner's manuals, we do not believe this will
effectively reach all the affected parties. If the vehicle changes
owners, it is possible that the owner's manual will not be included
with the vehicle. In this case, the new owner would be oblivious to
this information. To address the problem in a more universal manner and
reach a larger portion of the affected parties, the agency began to
issue annual consumer advisories about the hazards of carbon monoxide
in the Fall of 1996.
These advisories alert drivers of all vehicles to the dangers of
letting vehicles idle in enclosed spaces, the importance of maintaining
the exhaust system, and that snow or other debris must be cleared from
the exhaust area before starting the vehicle. Mr. Denenberg's final
request was for NHTSA to include information about the availability and
value of carbon monoxide detectors in these consumer advisories.
Regarding this request, the agency will consider adding this
information to the next consumer advisory on this subject.
In accordance with 49 CFR part 552, this completes the agency's
review of the petition. The agency has concluded that there is no
reasonable possibility that the amendments requested by the petitioner
would be issued at the conclusion of a rulemaking proceeding.
Accordingly, it denies Mr. Denenberg's petition.
Authority: 49 U.S.C. 30103, 30162; delegation of authority at 49
CFR 1.50 and 501.8.
Issued on: September 16, 1997.
