The HACS data base is the computerization of the Chemical Hazards Response Information Service (CHRIS) Manuals 2 and 3. It is currently available only to USCG R&D and the National Response Center (NRC), on a 24-hour manned line for receiving reports on accidents. The NRC has mainly been used for oil spill reports which are then run through HACS. Incorporated in HACS are the 18 different spill models in Manual 3 and the chemical data in Manual 2. Each accident is analyzed and fit into a model. HACS can be used to set up a tree-like model that will show how each step of the accident will proceed--how quickly the cargo will disperse, the expected extent of the spill and its effects on the marine environment, etc. Inputs into HACS include all data available on the spill-the time of the spill, weather and sea conditions, location, vessel and hull types, etc.
