Specifically, you ask questions regarding the explosive weight of shaped\ncharges for jet perforating guns (JPGs).\nWe have paraphrased and answered your questions as follows:\nQ1. You ask whether the conditions outlined in SP 114(a) mean that only the explosive\nweight of the shape charges assembled in the JPGs count towards the 90.5 kg (200\npounds) limit per vehicle and not the other possible explosive components of a loaded\nJPG (e.g., a detonator cord or a booster).\nA1. The answer is yes. The 90.5 kg (200 pounds) limit per vehicle applies to the explosive\nweight of the shaped charges of the JPGs and does not include other explosive articles in\nthe JPG such as a detonator cord or a booster.\nQ2. You ask whether the net explosive weight of other explosives shipped in accordance with\n§ 177.848 on the same transport vehicle needs to be taken into consideration when\ntransporting loaded JPGs that do not exceed the 90.5 kg (200 pounds) limit per vehicle.\nA2. The answer is no. Other explosives offered for transportation on the transport vehicle are\nnot counted towards the 90.5 kg (200 pounds) limit per vehicle.\n\n<<<PAGE 2>>>\n\nI hope this information is helpful.

The total weight of the explosive contents of the shaped charges assembled in the guns does not\nexceed 90.5 kg (200 pounds) per vehicle; and\nb. The guns are packaged in accordance with Packing Method US 1 as specified in §173.62 of this\nsubchapter.\nSpecifically, in SP 114(a) it states that the total weight of the explosive content of the shaped charges\nassembled in the guns does not exceed 90.5 kg (200 pounds) per vehicle.\nQuestion 1: Does the statement in SP 114(a) mean that only the explosive weight of the shape charges\ncounts toward the 90.5 kg (200 pounds) per gun and not the other possible explosive components of a\nloaded jet perforating gun, such as detonator cord and a booster?\nQuestion 2: When transporting loaded jet perforating guns that do not exceed 90.5 kg (200 pounds) per\nvehicle, do we need to take into consideration the net explosive weight of other explosives shipping on\nsame vehicle (in this case the other explosives meet the segregation requirements per 49 CFR 177.848\nand may transport on same vehicle).\nYour consideration of this request is appreciated. Please let me know if additional information is\nneeded.
