No. 14-0174 Dear Mr. Hilmar Leng: This is a response to your September 17, 2014 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) with regard to quantity limitations for Division 2.2 non-flammable compressed gas transported by passenger aircraft. Specifically, you are requesting clarification on which quantity limitation is applicable under § 175.75(c) for Division 2.2 non-flammable compressed gas when there are subsidiary risks involved. The net weight quantity limitation of 75 kg for Division 2.2 non-flammable compressed gas specified in § 175.75 (c) is applicable regardless of the subsidiary hazards. The subsidiary hazard does not need to be considered, provided the material is otherwise authorized for carriage by passenger aircraft. I hope this information is helpful. If you have any more questions, please do not hesitate to contact this office again.

The regulations state that if hazardous material is loaded in an inaccessible manner on board a. passenger aircraft, the limits per inaccessible compartment/hold of hazardous material is limited to 25 Kg and in addition 75 Kg of non-flammable gas class 2.2. The clarification we need is the 75 Kg restriction for non-flammable gas when there is also a etc. For these cases, does the 75 Kg rule still apply or are we now obliged to adhere to the 25 sub-risk involved e.g. some Aerosols UN1950 2.2 (8), UN 1072 Oxygen compressed 2.2 (5.1) Kg rule?
