Some 50 people, immigration officers and protesters alike, were injured in the resultant conflagration before it was extinguished by the building sprinkler system.
During major conflagrations, they will serve as support units, ferrying supplies and airlifting injured firefighters as well as routine water dropping.
Undaunted, the rescuers pulled out the seriously wounded and delivered fire-fighting supplies to the sailors who refused to surrender their ship to the conflagration.
