Don't make a mockery of a mock drill

The recent unfortunate death of a young woman  volunteer in a mock drill at Bangalore, speaks volumes of the state of emergency preparedness. In many chemical plants, mock drills are conducted by informing everyone about the timing of the drill. What is the purpose of this if you want to test your real emergency preparedness? In 1995 I attended an advanced firefighters and rescue training at Dubai where not only were we made to fight live natural gas fires generated in a natural gas skid mounted mock plant ( we had to isolate the supply of natural gas) but also made to search for victims inside buildings. Smoke bombs were placed inside the buildings to disorient us, along with strobe lights that were flashing ( also to disorient us). The instructors place a lot of emphasis on the safety of the firefighters and rescue team. Recently I read an article about a new training tool for firefighters in this link.
Always be prepared and don't make a mockery of a mock drill.
