Dear Ms. Jackson:
This is in response to your August 30, 2005 letter regarding the applicability of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 100-180) to a device that your
company calls the Eclipse Oxygen System.
You state in your letter that the Eclipse Oxygen System is a device that separates oxygen
from ambient air for delivery to patients who require supplemental oxygen therapy. This
device consists of a lightweight, portable oxygen concentrator with an integrated oxygen
delivery valve for continuous flow or pulse delivery. The process by which oxygen is
separated is called Pressure Swing Absorption (PSA). The maximum pressure of the
oxygen exerted within the Eclipse Oxygen System packaging is 23.7 psia during normal
operation at 20 °C. The device can be powered by multiple power sources, including AC
or DC power, an AC adapter, rechargeable lithium ion batteries, and an automobile
cigarette lighter adapter. The battery pack consists of 24, 2.2 ampere-hour lithium ion
cells, and the total equivalent lithium content of the battery pack is 15.8 grams. The
lithium ion battery pack has been tested pursuant to the United Nations Manual of Tests
and Criteria and is packaged in a manner to prevent short circuits when offered for
transport or carried onboard passenger aircraft. You ask whether this device is regulated
as a hazardous material under the HMR.
Based on the information provided, the Eclipse Oxygen System portable oxygen
concentrator is not currently subject to the HMR because: (1) the pressure of the oxygen
in the device does not exceed 40.6 psia at 20 °C; (2) the lithium ion battery used to
operate the device is excepted from the HMR (§ 173.185(c)(2))); (3) the portable oxygen
packaged in a manner to preclude it from creating sparks or generating a dangerous
concentrator contains no other materials subject to the HMR; and (4) the battery pack is
quantity of heat (for example, by the effective insulation of exposed terminals).
In accordance with the 2005-2006 Edition of the International Civil Aviation
Organization Technical Instructions for the Safe Transport of Dangerous Goods by Air,
your device is regulated as a Class 9 material when transported as cargo onboard
passenger and cargo aircraft. However, the device may be authorized for transportation
onboard passenger aircraft as consumer electronic devices containing lithium ion

batteries with up to 25 grams of equivalent lithium content when carried by passengers or
crew for personal use and protected so as to prevent short circuits.
In addition, Federal Aviation Administration (FAA) approval is required before these
electronic devices are used by passengers on board aircraft. The FAA published a final
rule in the Federal Register regarding these devices on July 12, 2005 (70 FR 40156).
You may be interested to know that, in a notice of proposed rulemaking published under
Docket HM-224E on December 15, 2004 (69 FR 75207), the Pipeline and Hazardous
Materials Safety Administration has proposed to eliminate the 25-gram exception for
lithium batteries found under § 173.185(c)(2) of the HMR. Please refer to our website at
hazmat.dot.gov under the Rules and Regulations icon, in the rulemaking and Federal
Register Notices section.
I trust this satisfies your inquiry.

Re: Classification of SeQual Technologies' Eclipse™ Oxygen System
Dear Mr. Gale:
Thank you very much for taking the time on the phone and allowing me to speak
with you regarding SeQual Technologies' portable oxygen concentrator (POC) device
from the Pipeline and Hazardous Materials Safety Administration (PHMSA) that the
known as the Eclipse™ Oxygen System. I am writing to request written confirmation
Eclipse™ Oxygen System is not subject to the U.S. hazardous materials regulations
(HMR).
Background
The SeQual Eclipse Oxygen System is a device that separates oxygen from
concentrated oxygen is used for delivery to patients with Chronic Obstructive
ambient air through a process called Pressure Swing Adsorption (PSA). The
Pulmonary Disease (COPD) that require supplemental oxygen therapy. The Eclipse
provides a solution to address both stationary and portable requirements for oxygen
patients having prescriptions of up to 3 LPM full flow operation and up to 6 LPM flow
in a pulse flow mode operation. It consists of a lightweight, portable oxygen
concentrator with an integrated oxygen delivery valve for continuous flow or pulse
delivery and is capable of being operated directly from an AC or DC power source or
from rechargeable lithium ion batteries. It can be recharged and/or powered by a
separate AC adapter for use by the patient or where standard AC line power is available.
The DC power adapter accessory allows power to be provided by a DC auxiliary power
outlet, such as in a motor vehicle during transportation. User changeable battery packs
are available to provide a range of ambulatory operational time.
The Eclipse Oxygen System achieves its performance through SeQual's
patented Advanced Technology Fractionator (ATF®) technology and patented variable

speed compressor and compressor drive, advanced molecular sieve materials and
rechargeable batteries. This system will expand an oxygen patient's ability to travel via
aircraft and improve the patient's quality of life.
Class 2, Division 2.2 Gas - 49 CFR 173.115
The maximum pressure of the oxygen exerted within the Eclipse Oxygen
System packaging currently is 23.7 psia during normal operation at 20° C. This is
substantially less than the 40.6 psia at 20° C referenced in 49 CFR 173.115(b)(1) for
defining a Division 2.2 gas. Therefore, it is our opinion that the oxygen exerted within
the Eclipse Oxygen System is not a Division 2.2 gas and thus is not subject to the U.S.
HMR.

Lithium ion Batteries - 49 CFR 173.185
The Eclipse Oxygen System is powered by a lithium ion battery pack that has
been tested pursuant to the UN Manual of Tests and Criteria. The. pack is a unique
design in that it contains two independent batteries. Each battery is electrically isolated
and mechanically separated to prevent short circuits. The batteries are housed in a
single, sturdily constructed plastic enclosure. The entire battery pack consists of 24, 2.2
how
ampere-hour lithium ion cells. Therefore, the pack contains an aggregate equivalent
lithium content of 15.8 grams.
Based on the requirements contained in 49 CFR 173.185(c), it is our opinion
that the lithium ion battery pack is not subject to the HMR since the cells contain not
more than 5 grams of equivalent lithium content, the battery pack contains not more
than 25 grams of equivalent lithium content, the battery pack is of the type proven to be
non-dangerous by testing in accordance with tests in the UN Manual of Tests and
Criteria, and it will be packed in such a way to prevent short circuits when offered for
transport or carried onboard passenger aircraft.
We also would like to point out that the U.S. HMR contain the following
exception in 49 CFR 175.10(a)(27) (as amended by PHMSA's Interim Final Rule HM-
224E) for passengers and crew members:
... consumer electronic and medical devices (watches, calculators, cameras,
cellular phones, lap-top computers, camcorders, and hearing aids, etc.)
containing lithium cells or batteries, and spare lithium batteries and cells for
these devices, when carried by passengers or crew members in carry-on or
checked baggage for personal use. In addition, each installed or spare battery
must conform to the following: (i) The lithium content of the anode of each cell,
when fully charged, is not more than 5 g; and (ii) The aggregate lithium content
of the anodes of each battery, when fully charged, is not more than 25 g:"
This provision is generally consistent with one found in the ICAO Technical
Instructions that authorizes consumer electronic devices containing lithium ion batteries
with up to 25 grams of equivalent lithium content to be carried onboard passenger
aircraft.
