MIAMI (AP) - Authorities say four workers were hospitalized following a fuel spill at Miami International Airport.
    
Miami-Dade Fire Rescue reports that the men were working on a Mexicana aircraft in a maintenance facility Wednesday afternoon when the spill occurred. Covered in jet fuel, the men were taken to nearby hospitals that were set up to handle hazmat situations.
    
Chief Jose Herrera says the workers were being treated as a precaution. There was no early indication that any of them would suffer lasting effects.
    
It wasn't immediately clear how much fuel leaked.
    
Crews were working on the clean-up Wednesday evening.
