2nd day internship..

2nd day of internship was so difficult with 1st day. we've to prepare a lot of solution, some easy, some hard. also have to do MgO and CaO test which using HCl 35%.. a lot of fumes coming out, very dangerous!! Other preparation of reagent also involved in using 85% phosphorus acid... while preparation of NH4Cl using high molarity ammonia, causing whole lab full of strong ammonia smell!! stucked inside the room... we cannot open door or window as outside high dust density, inhale more will gives us cancer, i think... scary..

While lunch time, explosion time for the rocks area!! strong explosion outside.. people said that last time the rocks from explosion flew to the building and damaged the building, and some car was hit by the rocks too.. dangerous...The day was dangerous but better as more things to do, more fast can back, hehe...
