Page 1U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Avenue, SE Washington, D.C. 20590 SEP 1 7 2008 Mr. John M. Lansdown Director of Research OxySure Systems, Inc. 10880 John W. Elliott Rd., Suite 600 Frisco, TX 75034 Ref. No. 08-0095 Dear Mr. Lansdown: This is in response to your letter and subsequent telephone conversations with members of my staff regarding the Hazardous Materials Regulations (HMR; 49 CFR 17 1 - 180) applicable to chemical oxygen generators. We apologize for the delay in responding and hope it has not caused any inconvenience. In your letter, you state that your company manufactures a portable chemical oxygen generator, the OxySure Model 61 5, which delivers medically pure oxygen for use in cardiovascular, respiratory, and general medical emergencies. You state the initiation of oxygen generation is via a mechanical mechanism which releases a plunger. The plunger breaks the internal seals, bringing the oxygen-producing powder and catalyst together in a "slurry." You state that the housing and most of the internal parts are injection-molded plastic, and oxygen is delivered via a latex-free tubing and mask assembly. You ask whether an approval is required for the transportation of your product. The answer is yes. As currently required in Special Provision 60, a chemical oxygen generator that is shipped with its means of initiation attached must incorporate at least two positive means of preventing unintentional actuation of the generator, and be classed and approved by the Associate Administrator. In addition, the HMR regulations pertaining to a chemical oxygen generator are applicable to your product, including, after October 1,2008, compliance with 4 173.168, which includes impact resistance, packaging, and marking requirements. I hope this satisfies your inquiry. Sincerely, Director Office of Hazardous Materials Standards#

DOT/PHMSA Office of Hazardous Materials Specbl Permits and Approvals, PHH-30 Via DHL, Facsimile: (202) 366-3308 and Email. phmsaapprovaJs@dot.gov Dear Sir/Madam, *Ihank you for your call yesterday and we are very pleased to learn that a revision to the regulations regarding chemical o m e n genenton may be imminent. We have a mksion- critical and time-critical need to get direction in this regard. Our technology is vasdy different to the old chlonte technology (for whrch the cumnt regulations is written) used in commercial aircraft, and was developed preciseky to e b t e the h a z d associated with it and orher, d t i o n a l oxygen delivery systems. In fact, our first product, the OxySureq Model 615 was deemed safe enough by the Food & Drug Administration to be approved for Over-the-Counter (OTCJ sale ro consumers as a Class I1 medical device (Approval number K052396). Background and Model 615 OxySure' Systems, Inc. spent the last 6 ~ a r s developing a next-generation technology for the delivery of medical o q e n through a safe chemical process. In the process, we have developed numerous patents on the technology Our f i t product based on this technology is a Portable Emergency Olrygen Generator called Model 615. Model 615 is indicated by the FDA to be used for emergency oxygen, usually in cardiac, respiratory ox other generaf medical emergencies. It is also well suited for applications in civil emergencies and other homeland security applications. The product is designed to pmvenr harm or possibly deah in emergency situations by provichg lifesaving o m e n , It is designed to be safe and simple to we, such that any bystander or layperson can administer medical oxygen while waiting for the f i t responders to amve on the scene. The OxySure@ Model 615 produces a minimum of 6 Liters per minute for a minimum of 15 minutes of medically p u t (USP) oxygen. This is the FDA standard for emergency oxygen, Model 615 was developed specifically to fill the need for a safe, easy to use portable oxygen source that did not have the risks associated wirh compressed gas cyh&rs, liquid oxygen, or the type of emergency oxygen source used in commercial aircrafr. Like a fire extinguisher, Model 615 can be safely pre-positioned in homes, buildings and other public and private s e w s to provide immedidte medical g d e oxygen in an emergency Model 615 has already been used in published cases where lives were saved b u g h its use, including rhc case of an 10880 John W E b t t RDd, Suite 600, Frisco, TX 75034 USA F~%co, Texas Office: (cl) 888-70XYSURE Fax (+I) 972-294-6501 VLtgjnia Office: (+I) 703-687-1616 Fax: (+I) 703-580-7496#

Page 4eiernentay school child in South C m h . In January 2008 the OxySw@ Model 6 15 was named to the 2008 List of the World's Best Technologies. Technology The OxySure" Model 615 contains 3 components stond in separate hermetically sealed comparunenes: an inert, dry powder, which IS the oxygen source, a catalyst, and a Lquid, U& a compressed gas some, Model 615 does not contain a regulator, but rather produces oxygen at very close to atmospheric pressure. The initiation of oxygen generation is via a mechanical mechanism which leases a plastic plunger that breaks the k n a l seals bringing the oxygen producing powder and catalyst together in a slw T h e housing and most of rhe internal parts are injection- molded plastic. Lifesaving oxygen is delivered to the person in need via a laex-free tubing and mask assembly The chemicd component5 a x stored ins& a self-contained, dqosable cartridge.. The operating tempencures are much lower than traditional chemical oxygen generators and thus the device is not capable of ignitmg a fire. The device operates at very close to atmospheric pressure so it does not present the types of hazards represented by compressed gas cyhders or liquid oxygen. The device is not an explosion hazard. The chemicals are non toxic and envimnmentdy safe. Not a Temperature Hazard 'The OxySure" process results in oxygen generation at a temperanue much lower than traditional chemical oxygen generators used in commercd aircraft as PSUs, The outside swface of the unit only rises a few degrees F and the temperature of the oxygen produced increases typically only 5 tr, 10 degrees F above arnbient temperam, TypicaZly, the b r e a k temperam experienced by the user is less than 90" F. The temperanws within the sluny of the reacuon are typicaly in the 150°F range, well below h e temperam needed to initiate combusuon. O f come, the user 15 we1 insulated from the reaction core, such that the touch wmperanue of the cartridge is far less than that of a Starbucks coffee cup. Not an Exploeion Hazard The OxySure" Model 615 is not an explosion hazard. T h e oxygen generating process is initiated with the turn of a knob, causing the oxygen containing powder, catalyst and liquid to be instantly combined inside the caruidge. Prior to the reaction, the powders are dry and inert. Post-reacuon, the residue of the reaction consists of a harmless slurry. Therefore, Model 615 is not an explosion h a a d , either prior to the reanion or after. Funhexmore, we have completed several tesrs with Model 615 in the presence of a fire. We found that when the canridges are placed in a fire, the plastic components simply melt. Non-activated canridges placed in a fire melted, leasing the liquid in some cases. Even activated cartridges placed in a fire did not markedly enhance the activity of the f i , if at all. In swnrmry, Model 615 is not an explosion trazard, not undcr normal cixrurnsrances nor under the aggravated cirsumstances of a fire. Not a Toxicity Hazard The oxygen producing powder used in Model 615 does not represent a toxiciry hazard in the same way that, for example, the barium peroxide (used presently in commercial aircraft) repesents a toxicity hazard. From our MSDS p u will see that accidental contact with the#

Not an Environmental Hazard Upon accidental release due to the integrity of the c+e being broken, for exampIe, during shipment, the oxygen producing powder does not represent an environmental hazard. O n c e the cartridge is spent, it con& a slurry which is safe to dispose of regular household trash. Not a Pressure Hazard OxySureae Model 615 is a non-pressurized oxygen source. Oxygen gas is not stored in the caruidge but rahex produced upon activation. Under n o d operating condttions, the p~ssure within the system is well witkin 1 atm Pressure =lief valves az the top of each chamber prevent the caruidge from developing an internaI pressure higher than 1 am. in case of an accidental activation, ie., activation without the mask tubing attached. ?his is a summuy of the signhicant safety technologies incorporated into the OxjSure* Model 615 Emergency Oxygen synem.
