Consequence modeling of one liter Bromine leak was estimated in different scenarios (i.e. One liter glass bottle was damaged instantaneously, release of Bromine through 25 mm leak size from bottom of round glass flask having 50 liters capacity and 50 liters Bromine glass flask was damaged instantaneously). The toxic area of ERPG-3 (i.e. 5PPM) of Bromine was covered up to 280 meters, 285 meters, 1600 meters under different scenarios one liter glass bottle was damaged, release of Bromine through 25 mm leak size from bottom of round glass flask having 50 liters capacity and 50 liters Bromine glass flask was damaged respectively. Some important guidelines also proposed which may be useful to prevent the leakage of Bromine or reduce the exposure concentration during leakage of Bromine [ABSTRACT FROM AUTHOR]
