Photograph. Black and white photo showing two Marine Pollution Control workmen who are performing a training exercise. The workmen are standing on the deck of a barge and are vacuuming an absorbent material (possibly fiber pearl) or foam from the water surface. The foam is used on gasoline spills to prevent fires. Industrial cranes (possibly on the Rouge River near Zug Island) can be seen on the shoreline in the background.
