Andelyn Biosciences — Hazardous Materials Safety Interpretation

Page 1U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Avenue, SE Washington, DC 20590 May 1, 2024 Dave Curl Andelyn Biosciences 1180 Arthur E. Adams Dr. Columbus, OH 43221 Reference No. 23-0067 Dear Mr. Curl: This letter is in response to your July 6, 2023, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to infectious substances. In your email, you state that your company transports “UN3373, Biological substance, Category B, 6.2” with dry ice in a non-specification packaging in conformance with § 173.199. You note that this includes conformance with the § 178.609(d) drop tests, as required in § 173.199(a)(4). You state that your company would like to add additional mylar bags to the inner packaging that were not present when the drop tests were completed. You ask whether this modification to the inner packaging would require the entire package configuration to be retested. The answer is no. Section 173.199 prescribes the packaging requirements for a Division 6.2 Category B infectious substance. This section requires that a Category B infectious substance be packaged in a triple packaging that is designed, constructed, and maintained so that under conditions normally encountered in transportation, there will be no release of the hazardous material into the environment. The package must also be capable of passing the drop tests in § 178.609(d), in accordance with § 173.199(a)(4); however, it does not require retesting and is not subject to the design qualification testing, periodic retesting, or record retention (i.e., test report requirements) in § 178.601. It is the opinion of this Office that the minor revisions to the inner packaging configuration as described in your email would not require the entire package configuration to be retested. I hope this information helpful. Please contact us if we can be of further assistance. Sincerely, Steven Andrews Acting Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division#

Page 3From: Curl, Dave Sent: Thursday, July 6, 2023 11:42 AM To: infocntr@DOT.gov Subject: Packaging change review request To whom it may concern, My name is Dave Curl and I am the Logistics Manager for Andelyn Biosciences in Columbus, Ohio. We have been working closely with Sunoco Thermosafe to design a package to effectively handle our Gene Therapy products for ground and air shipments. I have attached the final testing reports for the 3 packages we are looking to move forward with. Our products will typically be UN3373 (Category B) on dry ice (UN1845). As you can see by the report, the packages will comply with all regulations spelled out in 49 CFR 173.199. The dilemma I have is that a large client of ours would like to add some additional layers of protection (mylar bags) in order to mitigate the risk of the Carbon Dioxide from the dry ice permeating their product. Below is a description of the changes we are proposing to the package and would appreciate your input as to whether or not there is a need for additional testing: What will be added are two mylar bags around a cryo box containing the product The first would be ziplocked and sealed with a tamper evident seal#

Page 4The product inside the first mylar back would then go inside of a 2nd mylar bag and heat sealed. Once heat sealed the product would then be placed into the 95kPa pressure bag with absorbent pads#

Page 5The 95kPa bag would then be sealed and placed into the payload box Finally the payload box gets placed into the Styrofoam cooler insert with dry ice and sealed up.#

Page 6The purpose of the request is to hopefully have your team review the additions to the package and provide some feedback on the proposed changes. We feel that the addition of the mylar bags just adds more layers of protection and really does not alter the effectiveness of the package. I would appreciate that you review the change and provide some guidance in order for us to proceed with meeting our customers expectations. Please feel free to reach out via email or phone if you have any additional questions or concerns. Thank you very much for your time!! Dave Curl Logistics Manager Andelyn Biosciences 1180 Arthur E.

Page 9Thermosafe Brands Job No. 22172U GAYNES LABS, INC. TEST OBJECTIVE: To subject packages, designed to transport Liquid Category B Biological Substances, to the applicable tests described in the Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, and Code of Federal Regulations, Title 49, Transportation, as requested by ThermoSafe Brands. ITEMS TESTED: Corrugated Fiberboard Boxes, Containing Eighty-One (81) 2-ml. Plastic Test Tubes, Package Model E3F4. Refer to Photos No. 1 through 11 for details of the package assembly. TESTS PERFORMED AND RESULTS: The tests were conducted in accordance with Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, Packing Instruction 650, and Code of Federal Regulations, Title 49, Transportation (49 CFR). The test methods are shown in parenthesis following the test name. DROP TEST: (49 CFR 178.609(d), (f)) (ICAO 6;6.5.3, PI 650 6)) (d) Samples must be subjected to free-fall drops onto a rigid, non-resilient, flat, horizontal surface from a height of 1.2 meters. The drops must be performed as follows: Where the samples are in the shape of the box, five must be dropped in sequence: (1) Flat on the bottom; (2) Flat on the top; (3) Flat on the long side; (4) Flat on the short side; (5) On a corner (f) The samples must be conditioned in an atmosphere of -18° C (0° F) or less for a period of at least 24 hours and within 15 minutes of removal from that atmosphere be subjected to the drop test, described in paragraph (d). See Photos No. 12 and 13 for overview of drop orientations. 2 Page of 31#

Page 10Thermosafe Brands Job No. 22172U GAYNES LABS, INC. CRITERIA FOR PASSING THE TEST: (49 CFR 178.609(d)(4)) (ICAO 6;6.5.3, PI 650 6)) Following the appropriate drop sequence, there must be no leakage from the primary receptacle(s), which should remain protected by absorbent material in the secondary packaging. DROP TEST RESULTS: Five (5) packagings were tested. Each test tube was filled to 98% of its maximum capacity with antifreeze. The packages were assembled as for shipment. Five (5) packages were dropped after being conditioned to -18° C (0° F) for 24 hours. Drop After -18ºC (0ºF) Conditioning Sample Package Orientation Results 1 Flat Bottom No Damage/No Leakage - Pass 2 Flat Top No Damage/No Leakage - Pass 3 Flat Long Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 4 Flat Short Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 5 Bottom Corner (Mfg. Joint) Slight Distortion to Box at Corner/No Leakage - Pass VIBRATION TEST: (49 CFR. 178.608) (ICAO 4;4-(i) Note 4) Three (3) packages were tested. Each test tube was filled to 98% of its maximum capacity with water. The packages were assembled as for shipment. Land Vehicle Vibration: Three (3) complete packages were placed in their normal shipping orientation on the table of a vertical linear motion vibration machine, which has a displacement of one inch (peak to peak). Vertical fences were placed around packages in order to limit horizontal movement but not limit vertical movement (see Photo 14). The vibration frequency was adjusted to the minimum speed sufficient to cause the samples to leave the table momentarily so that a 1/16" shim could pass between the bottom of the packages and the machine table. The packages were subjected to a vibration frequency of 260 cycles per minute for a duration of one hour. Each package was inspected at the completion of the test. Aircraft Vibration: Three (3) packages as above were subjected to additional vertical linear motion vibration test. The packages were placed in their normal shipping orientation on the table of the vibration machine (see Photo No. 15) and subjected to the vibration at the frequencies and levels as described below. Each package was inspected at the completion of the test. A sweep of the frequencies/g levels shown was conducted over a duration of one hour. 7 – 25 Hz @ 1g 25 – 50 Hz @ 2g 50 – 100 Hz @ 4g 100 – 150 Hz @ 6g 150 – 200 Hz @ 8g 3 Page of 31#

Page 11Thermosafe Brands Job No. 22172U GAYNES LABS, INC. VIBRATION TEST REQUIREMENTS: The package must be capable of withstanding the effects of any acceleration, vibration or vibration resonance which may arise under conditions likely to be encountered in routine transport without any deterioration in the effectiveness of the closing devices on the various receptacles or in the integrity of the package as a whole. A packaging passes the vibration test if there is no rupture or leakage from any of the packages. No test sample should show any deterioration that could adversely affect transportation safety or any distortion liable to reduce packaging strength. VIBRATION TEST RESULTS: Land Vehicle Vibration: Sample No. Results 1 Slight Scuffing to Bottom of Box/No Leakage - Pass 2 Slight Scuffing to Bottom of Box/No Leakage – Pass 3 Slight Scuffing to Bottom of Box/No Leakage - Pass Aircraft Vibration: Sample No. Results 1 No Damage/No Leakage - Pass 2 No Damage/No Leakage - Pass 3 No Damage/No Leakage - Pass INTERNAL PRESSURE TEST: (ICAO Internal Pressure Variations Tests 4;4-(i) Note 3 and 4;4.8.6) Three (3) test tubes were placed inside the vacuum chamber, lying on their sides (see Photo No. 16). The pressure inside the vacuum chamber was gradually reduced to 5 kPa, creating and internal pressure inside the test tubes of 95 kPa. The pressure was maintained for a period of 30 minutes, while visually monitoring the samples for the appearance of leakage of contents. INTERNAL PRESSURE TEST REQUIREMENTS: The primary receptacle or the secondary packaging must be capable of withstanding, without leakage, an internal pressure, producing a pressure differential of not less than 95 kPa. 4 Page of 31#

Page 40Thermosafe Brands Job No. 22173U GAYNES LABS, INC. TEST OBJECTIVE: To subject packages, designed to transport Liquid Category B Biological Substances, to the applicable tests described in the Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, and Code of Federal Regulations, Title 49, Transportation, as requested by ThermoSafe Brands. ITEMS TESTED: Corrugated Fiberboard Boxes, Containing One Hundred Sixty-Two (162) 2-ml. Plastic Test Tubes, Package Model E6F4. Refer to Photos No. 1 through 11 for details of the package assembly. TESTS PERFORMED AND RESULTS: The tests were conducted in accordance with Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, Packing Instruction 650, and Code of Federal Regulations, Title 49, Transportation (49 CFR). The test methods are shown in parenthesis following the test name. DROP TEST: (49 CFR 178.609(d), (f)) (ICAO 6;6.5.3, PI 650 6)) (d) Samples must be subjected to free-fall drops onto a rigid, non-resilient, flat, horizontal surface from a height of 1.2 meters. The drops must be performed as follows: Where the samples are in the shape of the box, five must be dropped in sequence: (1) Flat on the bottom; (2) Flat on the top; (3) Flat on the long side; (4) Flat on the short side; (5) On a corner (f) The samples must be conditioned in an atmosphere of -18° C (0° F) or less for a period of at least 24 hours and within 15 minutes of removal from that atmosphere be subjected to the drop test, described in paragraph (d). See Photos No. 12 and 13 for overview of drop orientations. 2 Page of 31#

Page 41Thermosafe Brands Job No. 22173U GAYNES LABS, INC. CRITERIA FOR PASSING THE TEST: (49 CFR 178.609(d)(4)) (ICAO 6;6.5.3, PI 650 6)) Following the appropriate drop sequence, there must be no leakage from the primary receptacle(s), which should remain protected by absorbent material in the secondary packaging. DROP TEST RESULTS: Five (5) packagings were tested. Each test tube was filled to 98% of its maximum capacity with antifreeze. The packages were assembled as for shipment. Five (5) packages were dropped after being conditioned to -18° C (0° F) for 24 hours. Drop After -18ºC (0ºF) Conditioning Sample Package Orientation Results 1 Flat Bottom No Damage/No Leakage - Pass 2 Flat Top No Damage/No Leakage - Pass 3 Flat Long Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 4 Flat Short Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 5 Bottom Corner (Mfg. Joint) Slight Distortion to Box at Corner/No Leakage - Pass VIBRATION TEST: (49 CFR. 178.608) (ICAO 4;4-(i) Note 4) Three (3) packages were tested. Each test tube was filled to 98% of its maximum capacity with water. The packages were assembled as for shipment. Land Vehicle Vibration: Three (3) complete packages were placed in their normal shipping orientation on the table of a vertical linear motion vibration machine, which has a displacement of one inch (peak to peak). Vertical fences were placed around packages in order to limit horizontal movement but not limit vertical movement (see Photo 14). The vibration frequency was adjusted to the minimum speed sufficient to cause the samples to leave the table momentarily so that a 1/16" shim could pass between the bottom of the packages and the machine table. The packages were subjected to a vibration frequency of 260 cycles per minute for a duration of one hour. Each package was inspected at the completion of the test. Aircraft Vibration: Three (3) packages as above were subjected to additional vertical linear motion vibration test. The packages were placed in their normal shipping orientation on the table of the vibration machine (see Photo No. 15) and subjected to the vibration at the frequencies and levels as described below. Each package was inspected at the completion of the test. A sweep of the frequencies/g levels shown was conducted over a duration of one hour. 7 – 25 Hz @ 1g 25 – 50 Hz @ 2g 50 – 100 Hz @ 4g 100 – 150 Hz @ 6g 150 – 200 Hz @ 8g 3 Page of 31#

Page 42Thermosafe Brands Job No. 22173U GAYNES LABS, INC. VIBRATION TEST REQUIREMENTS: The package must be capable of withstanding the effects of any acceleration, vibration or vibration resonance which may arise under conditions likely to be encountered in routine transport without any deterioration in the effectiveness of the closing devices on the various receptacles or in the integrity of the package as a whole. A packaging passes the vibration test if there is no rupture or leakage from any of the packages. No test sample should show any deterioration that could adversely affect transportation safety or any distortion liable to reduce packaging strength. VIBRATION TEST RESULTS: Land Vehicle Vibration: Sample No. Results 1 Slight Scuffing to Bottom of Box/No Leakage - Pass 2 Slight Scuffing to Bottom of Box/No Leakage – Pass 3 Slight Scuffing to Bottom of Box/No Leakage - Pass Aircraft Vibration: Sample No. Results 1 No Damage/No Leakage - Pass 2 No Damage/No Leakage - Pass 3 No Damage/No Leakage - Pass INTERNAL PRESSURE TEST: (ICAO Internal Pressure Variations Tests 4;4-(i) Note 3 and 4;4.8.6) Three (3) test tubes were placed inside the vacuum chamber, lying on their sides (see Photo No. 16). The pressure inside the vacuum chamber was gradually reduced to 5 kPa, creating and internal pressure inside the test tubes of 95 kPa. The pressure was maintained for a period of 30 minutes, while visually monitoring the samples for the appearance of leakage of contents. INTERNAL PRESSURE TEST REQUIREMENTS: The primary receptacle or the secondary packaging must be capable of withstanding, without leakage, an internal pressure, producing a pressure differential of not less than 95 kPa. 4 Page of 31#

Page 43Thermosafe Brands Job No. 22173U GAYNES LABS, INC. INTERNAL PRESSURE TEST RESULTS: Internal Pressure: Tube No. Results 1 No rupture or leakage – Meets Test Requirements 2 No rupture or leakage – Meets Test Requirements 3 No rupture or leakage – Meets Test Requirements CONCLUSION On the basis of the tests conducted, the submitted package type, described as a Corrugated Fiberboard Box Containing One Hundred Sixty-Two (162) 2-ml. Plastic Test Tubes, Package Model E6F4, meets the requirements for transport of Liquid Category B Biological Substances, described in the Technical Instructions for the Safe Transport of Dangerous Goods by Air, and Code of Federal Regulations, Title 49, Transportation Notes: The packagings used in testing are to represent the containers as prepared for actual transport. The use of any other packaging methods or components may render the package invalid and may be subject to fine by DOT. It is the shipper’s responsibility to comply with all pertinent requirements for specific material being shipped, including requirements for quantities of materials, various transportation modes and any additional requirements, which may be imposed by various carriers. 5 Page of 31#

Page 71Thermosafe Brands Job No. 22174U GAYNES LABS, INC. TEST OBJECTIVE: To subject packages, designed to transport Liquid Category B Biological Substances, to the applicable tests described in the Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, and Code of Federal Regulations, Title 49, Transportation, as requested by ThermoSafe Brands. ITEMS TESTED: Corrugated Fiberboard Boxes, Containing Four Hundred Eighty-Six (486) 2-ml. Plastic Test Tubes, Package Model E12F4. Refer to Photos No. 1 through 11 for details of the package assembly. TESTS PERFORMED AND RESULTS: The tests were conducted in accordance with Technical Instructions for the Safe Transport of Dangerous Goods by Air, ICAO, Packing Instruction 650, and Code of Federal Regulations, Title 49, Transportation (49 CFR). The test methods are shown in parenthesis following the test name. DROP TEST: (49 CFR 178.609(d), (f)) (ICAO 6;6.5.3, PI 650 6)) (d) Samples must be subjected to free-fall drops onto a rigid, non-resilient, flat, horizontal surface from a height of 1.2 meters. The drops must be performed as follows: Where the samples are in the shape of the box, five must be dropped in sequence: (1) Flat on the bottom; (2) Flat on the top; (3) Flat on the long side; (4) Flat on the short side; (5) On a corner (f) The samples must be conditioned in an atmosphere of -18° C (0° F) or less for a period of at least 24 hours and within 15 minutes of removal from that atmosphere be subjected to the drop test, described in paragraph (d). See Photos No. 12 and 13 for overview of drop orientations. 2 Page of 31#

Page 72Thermosafe Brands Job No. 22174U GAYNES LABS, INC. CRITERIA FOR PASSING THE TEST: (49 CFR 178.609(d)(4)) (ICAO 6;6.5.3, PI 650 6)) Following the appropriate drop sequence, there must be no leakage from the primary receptacle(s), which should remain protected by absorbent material in the secondary packaging. DROP TEST RESULTS: Five (5) packagings were tested. Each test tube was filled to 98% of its maximum capacity with antifreeze. The packages were assembled as for shipment. Five (5) packages were dropped after being conditioned to -18° C (0° F) for 24 hours. Drop After -18ºC (0ºF) Conditioning Sample Package Orientation Results 1 Flat Bottom No Damage/No Leakage - Pass 2 Flat Top No Damage/No Leakage - Pass 3 Flat Long Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 4 Flat Short Side (Adjacent to Mfg. Joint) No Damage/No Leakage - Pass 5 Bottom Corner (Mfg. Joint) Slight Distortion to Box at Corner/No Leakage - Pass VIBRATION TEST: (49 CFR. 178.608) (ICAO 4;4-(i) Note 4) Three (3) packages were tested. Each test tube was filled to 98% of its maximum capacity with water. The packages were assembled as for shipment. Land Vehicle Vibration: Three (3) complete packages were placed in their normal shipping orientation on the table of a vertical linear motion vibration machine, which has a displacement of one inch (peak to peak). Vertical fences were placed around packages in order to limit horizontal movement but not limit vertical movement (see Photo 14). The vibration frequency was adjusted to the minimum speed sufficient to cause the samples to leave the table momentarily so that a 1/16" shim could pass between the bottom of the packages and the machine table. The packages were subjected to a vibration frequency of 260 cycles per minute for a duration of one hour. Each package was inspected at the completion of the test. Aircraft Vibration: Three (3) packages as above were subjected to additional vertical linear motion vibration test. The packages were placed in their normal shipping orientation on the table of the vibration machine (see Photo No. 15) and subjected to the vibration at the frequencies and levels as described below. Each package was inspected at the completion of the test. A sweep of the frequencies/g levels shown was conducted over a duration of one hour. 7 – 25 Hz @ 1g 25 – 50 Hz @ 2g 50 – 100 Hz @ 4g 100 – 150 Hz @ 6g 150 – 200 Hz @ 8g 3 Page of 31#

Page 73Thermosafe Brands Job No. 22174U GAYNES LABS, INC. VIBRATION TEST REQUIREMENTS: The package must be capable of withstanding the effects of any acceleration, vibration or vibration resonance which may arise under conditions likely to be encountered in routine transport without any deterioration in the effectiveness of the closing devices on the various receptacles or in the integrity of the package as a whole. A packaging passes the vibration test if there is no rupture or leakage from any of the packages. No test sample should show any deterioration that could adversely affect transportation safety or any distortion liable to reduce packaging strength. VIBRATION TEST RESULTS: Land Vehicle Vibration: Sample No. Results 1 Slight Scuffing to Bottom of Box/No Leakage - Pass 2 Slight Scuffing to Bottom of Box/No Leakage – Pass 3 Slight Scuffing to Bottom of Box/No Leakage - Pass Aircraft Vibration: Sample No. Results 1 No Damage/No Leakage - Pass 2 No Damage/No Leakage - Pass 3 No Damage/No Leakage - Pass INTERNAL PRESSURE TEST: (ICAO Internal Pressure Variations Tests 4;4-(i) Note 3 and 4;4.8.6) Three (3) test tubes were placed inside the vacuum chamber, lying on their sides (see Photo No. 16). The pressure inside the vacuum chamber was gradually reduced to 5 kPa, creating and internal pressure inside the test tubes of 95 kPa. The pressure was maintained for a period of 30 minutes, while visually monitoring the samples for the appearance of leakage of contents. INTERNAL PRESSURE TEST REQUIREMENTS: The primary receptacle or the secondary packaging must be capable of withstanding, without leakage, an internal pressure, producing a pressure differential of not less than 95 kPa. 4 Page of 31#

Page 74Thermosafe Brands Job No. 22174U GAYNES LABS, INC. INTERNAL PRESSURE TEST RESULTS: Internal Pressure: Tube No. Results 1 No rupture or leakage – Meets Test Requirements 2 No rupture or leakage – Meets Test Requirements 3 No rupture or leakage – Meets Test Requirements CONCLUSION On the basis of the tests conducted, the submitted package type, described as a Corrugated Fiberboard Box Containing Four Hundred Eighty-Six (486) 2-ml. Plastic Test Tubes, Package Model E12F4, meets the requirements for transport of Liquid Category B Biological Substances, described in the Technical Instructions for the Safe Transport of Dangerous Goods by Air, and Code of Federal Regulations, Title 49, Transportation Notes: The packagings used in testing are to represent the containers as prepared for actual transport. The use of any other packaging methods or components may render the package invalid and may be subject to fine by DOT. It is the shipper’s responsibility to comply with all pertinent requirements for specific material being shipped, including requirements for quantities of materials, various transportation modes and any additional requirements, which may be imposed by various carriers. 5 Page of 31#
