Chemical spill in Ohio and FAA's response

A large chemical spill in Ohio has grounded flights and sparked mass evacuations due to nitric acid leakage from an industrial plant. The spill has led to an immediate evacuation order, with the FAA banning flights in the affected area. No injuries have been reported, but exposure to nitric acid can cause irritation and other health issues. This incident is reminiscent of a previous toxic chemical train derailment in East Palestine, which resulted in long-term health concerns and a lawsuit settlement.
