I remember when we went to the control room of that company. We saw that red sign to find danger. I don't know if it was for alarm or it was for security purposes.
I showed my friend and he jokingly said, "I'm going to push the button". We told him not to that this might go to an unbearable consequence. We are afraid so we have to drag him back so that he does not follow his urges and curiosity but we wonder what that may be.
After so many inquiries we find that that was just an emergency button in case of any fire attack in the company.
