Fire At SBI?

At first I thought, fire
broke out at main branch of State Bank
of India, all the staff of bank stepped down and gathered in the
parking area. But the viewers told, it was rehearsal of what to do in
case of fire break inside the building. The disaster management group
watered the outside walls by hose-pipe. And used the fire
extinguishers also. Then fire brigade came to cope with the situation. The trial
went this morning for half-n-hour. --
