On 8/28/06 @ 1919hrs. Engine 4 responded to a report of a van leaking oil. On arrival, Engine 4 crew found a 1977 Dodge van leaking numerous fluids, including power steering and transmission fluid. Absorbent was placed around the van to prevent the fluids from entering the storm drain. Upon further investigation, three 55 gallon drums were discovered inside the van (see below photo). Police were called to stand-by while the van was opened and the drums were checked. The drums were empty, containing only slight residue and the odor of Hydrocarbons. The van was towed and impounded. The incident served as a reminder of the hazards that may be encountered at a seemingly benign incident.
