Within 24 hours of embarkation of all passengers, the crew will conduct a mandatory muster drill in which the General Emergency Signal is sounded. The purpose of the drill is to educate passengers of emergency procedures should an actual emerg

15、 shall first be purged, using inert gas, until the HC (hydrocarbon) content reaches to below the critical dilution line or HC concentration in the tank atmosphere is less than 2% by volume. This is done so that during the subsequent gas freeing no portion of the tank atmosphere is brought within the

16、 flammable range. This inert gas used for purging shall contain Oxygen, less than 5% by volume, to ensure the above.The replacement of a tank atmosphere by inert gas can be achieved by either Inerting or Purging. In each of these methods one of two distinct processes, Dilution or displacement, will
