Airborne Labs International, Inc. — Hazardous Materials Safety Interpretation

Page 1U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Avenue, SE Washington, DC 20590 March 27, 2024 Aniyah Volpe Shipping Administrator Coordinator Airborne Labs International, Inc. 22C World’s Fair Drive Somerset, NJ 08873 Reference No. 23-0096 Dear Ms. Volpe: This letter is in response to your October 26, 2023, email and subsequent conversation with a member of my staff requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to customer shipments of carbon dioxide (CO2) sent to your company laboratory for quality control testing of a liquid CO2 source. Specifically, your company provides sampling kits, accompanied by specific instructions, for the collection and shipment of non-liquid phase CO2 in bags and mini-cylinders. You note that the CO2 samples collected in the sample bags are essentially at atmospheric pressure, and the CO2 in the sample mini-cylinders is at 25 psig or less, where the mini-cylinders incorporate a check valve to limit the pressure of the contents. It is your understanding, based on the classification criteria for Division 2.2 gases, that CO2 transported in containers at these pressures is not regulated as a hazardous material and request confirmation. Your understanding is correct. While CO2 is listed in the § 172.101 hazardous materials table as a Division 2.2 gas, the CO2 as described in your email does not meet the definition of a Division 2.2 gas when transported in a container at pressures below 29.0 psig at 68 °F (20 °C), nor is it transported as a liquified gas or cryogenic liquid (see § 173.115(b)). Furthermore, it would remain not regulated, provided that it does not meet the criteria for a hazardous waste, hazardous substance, marine pollutant, or any other hazard class or division. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, Dirk Der Kinderen Chief, Standards Development Branch Standards and Rulemaking Division#

Sincerely, Janaye From: Aniyah Volpe <Aniyah.Volpe@AIRBORNELABS.COM> Sent: Thursday, October 26, 2023 2:35 PM To: PHMSA HM InfoCenter <PHMSAHMInfoCenter@dot.gov> Cc: Mark Taylor <Mark.Taylor@AIRBORNELABS.COM>; Tracie Moran <Tracie.Moran@AIRBORNELABS.COM> Subject: Request for DOT Letter of Interpretation – Non-Hazardous Sampling Kits Importance: High CAUTION: This email originated from outside of the Department of Transportation (DOT). Do not click on links or open attachments unless you recognize the sender and know the content is safe. Good afternoon, To whom it may concern, I hope this email finds you well. My name is Aniyah Volpe I’m writing on behalf of Airborne Labs International a Commercial Laboratory that specializes in CO2 sampling. I’m writing to request a Letter of Interpretation from the Department of Transportation (DOT) regarding an issue we’ve been encountering with our No-Haz Sampling Kits in relation to carriers and foreign customs agents. We have been experiencing a recurring problem where our kits are mistakenly classified as hazardous materials by carriers and foreign customs agents. This incorrect classification has led to delays and complications in our shipping and export processes. Furthermore, foreign customs agents have also requested MSDS for our sampling kits, by us providing the MSDS documentation would lead to the incorrect classification of our products as hazardous materials. The situation is counterproductive to our efforts to ensure the correct handling and classification of our products.#

Page 3In light of these issues, we kindly request the DOT’s guidance and clarification in the form of a Letter of Interpretation. Specifically, we seek your guidance on how to prevent our Non-Hazardous sampling kits from being mistakenly categorized as hazardous materials, as well as how to handle requests for MSDS in a manner that avoids the misclassification of our products. Your expertise and assistance in resolving this matter are highly valuable to us, as we are committed to upholding the safety, compliance, and efficiency of our operations. We believe that a formal interpretation from the DOT will help clarify the regulations and guidelines governing the transportation of our products and alleviate these issues. To provide you with a more comprehensive understanding of our situation, I’ve attached a copy of our (FedEx letter with IATA instructions, our personal IATA instructions letter and our Final Product CO2 manual) that we currently provide when customs does reach out regarding an issue. We are sampling gaseous Carbon Dioxide; a division 2.2 Gas and our kits are designed to only hold 25 PSIG of pressure. Thus, per IATA this isn’t hazmat as also confirmed by the attached FedEx Letter. We appreciate your prompt attention to this matter and look forward to your guidance. If you require any additional information or documentation from our end, please don’t hesitate to reach out to us. I look forward to your reply! Kind regards, ___________________________________ Aniyah Volpe Shipping Administrator Coordinator Airborne Labs International, Inc. 22C World’s Fair Drive Somerset, NJ 08873 Email: traffic@airbornelabs.com T: 732-302-1950#

Page 4IATA Guidelines for Non-Hazardous Sampling Kit Reference to IATA Classification and Exceptions To Whom It May Concern, I am writing to provide important information regarding our Non-Hazardous Sampling Kit and its compliance with IATA guidelines. Please refer to the IATA guidelines (2023 Edition), specifically detailed in the IATA Classification on Page 167, Section 3.2.2.2, pertaining to gases that fall under Division 2.2, including: (a) Gases which are asphyxiant – Gases that dilute or replace the oxygen normally in the atmosphere. (b) Gases that are oxidizing – Gases that may, generally by providing oxygen, cause or contribute to the combustion of other materials more than air does. (c) Gases that do not come under other divisions. Our Non-Hazardous Sampling Kit, as indicated, does not contain gases falling under any of these classifications. Therefore, it complies with the specified IATA guidelines for Non-Flammable, Non-Toxic gases. Additionally, please refer to IATA Exceptions on Page 168, Section 3.2.2.4.1, (2023 Edition) which states that (Gases of Division 2.2 are not subject to these regulations if they are transported at a pressure less than 200 kPa at 20°C and are not liquefied or refrigerated liquefied gases.) Our Non-Hazardous Sampling Kit adheres to these criteria, confirming its exemption from certain IATA regulations. We emphasize that our Non-Hazardous Sampling Kit poses no threat during transportation, as it complies with these IATA guidelines and exceptions. It is essential to recognize that the contents of this kit are Non-Hazardous and do not present any danger to individuals, property, or the environment.

Page 5Non-Hazardous “No-Haz” Division 2.2 Gas Sample Kit Shipments by I.A.T.A. Definition Dear Customer, This letter concerns shipment of non-compressed Division 2.2 (non-flammable, non-toxic) gases including, for example: air, carbon dioxide (CO2), oxygen (O2), nitrogen (N2) argon (Ar) sulfur hexafluoride (SF6) samples in limited quantities to our laboratory for quality control testing. We have been assured by recognized experts at the International Compliance Center Ltd. and courier HAZMAT specialists that Division 2.2 gas samples that are taken according to supplied directions and shipped in our No-Haz Sampling & Shipping Kits (which include gas sampling bags, minicyls and 1L steel NVR container) can be properly labeled and shipped as a “non-hazardous commodity sample of no commercial value”. The technical reasons for this non-hazardous classification of Division 2.2 gas samples taken in our “No-HAZ” kits are as follows: 1.) Division 2.2 gases are those that have non-flammable and non-toxic properties. These gases are properly classified as dangerous materials (hazmat) only when they are compressed or liquefied. A compressed Division 2.2 gas is defined in IATA regulations as one which is “transported under pressure at or above 200 kPag (gauge) = 2.97 atm = 43.7 psia (29 psig) @ 20oC". This means that Division 2.2 gas samples should not be classified as hazmat if it is contained and shipped at a pressure less than this “compressed gas” definition value. As the pressure inside of a gas sampling bag is essentially 0 psig (14.7 psia) @ 20oC, it does not meet the conditions necessary for it to be IATA-defined as a hazardous material. Therefore non-compressed Division 2.2 gases in a sample bag is not a Div. 2.2 hazmat. The weight of Division 2.2 gas contained within a 2-3 x 2L sample bag is no more than approximately 37 g = 0.037 kg. The maximum acceptable amount of compressed gas meeting Division 2.2 HAZMAT definition requirements for passenger aircraft is 75 kg and 150 kg for cargo aircraft. 2.) The same IATA “exemption” definition descriptions outlined for a gas sampling bag also pertain to a non- compressed Division 2.2-defined gas samples stored in our minicyls. A minicyl is a small (ex. 75 – 500 cc [0.075 – 0.5L]) capacity US DOT cylinder that can be charged with no more than 25 psig of Div. 2.2 gas (fill-limited by a 25 psig check valve). Because of its design, the non-compressed, minimal amount (approx. 0.22-1.5L) of gas sample contained within a minicyl does not meet the definition of a Div 2.2 hazardous material. Therefore, non- compressed Div. 2.2 gas sample contained in a minicyl is not IATA-defined as hazardous material as per it’s “exemptions” description. 3.) Concerning our 1L NVR polished steel can, the customer takes a CO2 snow sample at their location and lets the snow evaporate within this can. This empty NVR can is then clip-lidded and shipped back within our No-Haz kit for lab examination for any trace non-volatile residue (ex. Particulates). Therefore this container is shipped as an empty can. It is the prerogative of your designed carrier to make a final decision concerning acceptance of your shipment. However, based upon the sound technical data listed above, which indicates total compliance with both the letter and spirit of IATA dangerous goods shipping regulations, ALI recommends that your kit sample be properly labeled as a “non-hazardous industrial sample of no commercial value”. Please see the attached confirmation of this letter’s contents by the Manager of Dangerous Goods – FedEx and contact us if you require assistance with your sample shipment. .
