Three TSA agents were treated for exposure to an unknown hazardous material at LaGuardia Airport on Wednesday morning, according to reports.
The victims suffered from eye irritation at a Terminal B security checkpoint just before 6 a.m., Fox 5 reported.
The Port Authority said the terminal remained open during the incident and that flights were not affected.
The emergency response is causing traffic delays on the Grand Central Parkway and the surrounding areas, the airport said on Twitter.
