Kaohsiung district prosecutors investigate site of deadly propene explosions (2014/08/04)

Kaohsiung district prosecutors examined a roadside culvert this morning to learn more about the first of a series of deadly blasts that struck the city late last week. They plan to return tomorrow to cut out a section of pipeline that was believed to be the source of the propene leak that was behind the blasts.

The intersection of Kaisyuan and Ersheng roads is the site of the first in a series of deadly gas explosions that struck Kaohsiung. A task force from the district prosecutors office was joined by a metallurgist in entering the culvert to determine the cause of the explosion. Of the three gas pipelines in the area, only LCY Chemical’s pipeline showed signs of damage, with a 4 by 7 centimeter rectangular hole visible, potentially indicating an area where a patch had fallen off.

Hsieh Chao-ching
Kaohsiung District Prosecutor
We need confirmation and permission from the authority in charge to cut this pipe. This action is part of our search and seizure, so we need you to pass this message on to your foreman or a company executive.

This request was made by prosecutors to an engineer of LCY Chemical Corp., prior to additional tests and documentation scheduled for tomorrow. Some 2 to 3 meters of the pipeline will be cut and sent for examination to determine if the hole was caused internally or externally.

Prosecutors plan to reconstruct the pipeline and examine it using high-tech instruments, as part of their comprehensive investigation.

Ground penetrating radar and other equipment will produce a 3D reconstruction of the underground area, providing further insight into what caused this deadly explosion.

檢扣押破管

檢方偵辦高雄氣爆案，上午勘驗第一爆炸點箱涵，發現李長榮化工四吋管疑似補釘脫落破洞，大小約7乘4公分，明天會割下扣押這段管線，送驗釐清破損原因，另外還會使用透地雷達等高科技儀器，確認石化管線和地下水道分布情形。

大爆炸第一氣爆點：高雄市凱旋和二聖路口，專案小組檢察官，在金屬研發中心專家陪同下，進入涵洞口。上方三條管線中，只有李長榮化工的四吋管受損，有個切割處完整、7乘4公分的長方形破洞，疑似補釘脫落。

[[高雄地檢署檢察官 謝肇晶]]
裁切的部分要請負責人確認，然後同意我們做裁切，我們要做搜索扣押的動作，這樣了解嗎?所以要能夠負責的人，比如說你們的廠長或者是高層人士。

檢察官要求在場的榮化工程師回去轉達高層，週二勘驗也得到現場作筆錄，還會鋸斷2到3公尺管線扣押送驗，確認破洞原因是由內而外或由外而內。

為了釐清大爆炸責任歸屬，管線重建是檢方偵辦重點，將動用高科技儀器地毯式清查。

GPR透地雷達，以高頻電磁波的反射訊號探勘，不必破壞地表，檢方彙整石化管線和地下水道分布情形，再製作3D立體透視圖，就能重新建構地底管線。
