EUNICE, La. (AP) -- Hundreds of people remained away from their homes again today as heat and fire kept cleanup crews away from the burned wreckage of a derailed train carrying hazardous chemicals.
Approximately 2,000 people forced out of their homes and businesses by Saturday's accident weren't allowed to return Monday -- and officials said they weren't sure when they would be.
''Until we can get in there and crews can analyze the status of the other cars, we really don't have a timeline on it,'' said Union Pacific Railroad spokesman Mark Davis.
The cars were to be inspected by Union Pacific, the National Transportation Safety Board and the Federal Railroad Administration.
Thirty of the train's 113 cars derailed about 75 miles west of Baton Rouge, sparking several blasts that sent fireballs skyward and shattered glass a quarter-mile away. Several cars were loaded with hazardous chemicals. No injuries were reported.
Police have said air monitoring equipment hadn't picked up any hazardous levels of chemicals. Acrylic acid has vapors that can irritate the lungs, nose and throat. Other chemicals on the train could cause dizziness, convulsions and death if large amounts are involved.
Firefighters moved in close enough Monday night to begin spraying two cars containing plastic pellets that were still burning.
''There also is still some concern about one car that is not visible,'' said state police Sgt. Howard McKee. ''They don't know what chemical is in the car. When it is cooled down, they will try to determine what's in the car and proceed from there.''
Earlier Monday, technicians detonated a tanker full of hazardous acid.
Shifting winds prompted the evacuation Monday of another 200 people.
Union Pacific said it would reimburse the evacuees.
Several lawsuits have already been filed against the railroad.
