※ This video is part of <Extreme Job - Explosion Technician 1-2> broadcast on April 30, 2009. From infrastructure construction such as roads and tunnels to building construction such as apartments, blasting is an important work that lays the foundation for various construction sites. A day at the site always begins with the loud noise of blasting that shakes the axis of the earth. Construction site blasting work, which can be easily thought of as simple blasting, must go through precise processes such as scientific design and test blasting by an explosives technician due to vibration, noise, and safety issues. A shipyard construction site on Geoje Island. Large-scale blasting work is underway to flatten a huge rocky mountain. The dust is so suffocating that it is impossible to work without a dust mask. Even if you change your dust mask, the dust is so strong that it quickly becomes black. In addition, the noise is so loud that earplugs are essential for those who have to work for two to three hours at a time. We meet people who are fighting with gunpowder to build a shipyard that spans 10,000 pyeong. ✔ Program name: Extreme Job - Gunpowder Blasting Technician Part 1-2 ✔ Broadcast date: 2009.04.30 #GolladyeonDocumentary #ExtremeJob #CivilEngineering #Construction #Construction #Gunpowder #Dynamite
