1 to hospital after chemical exposure at Utah base

HILL AIR FORCE BASE, Utah — Officials say an Air Force lieutenant sought medical attention after reporting he had been exposed to a chemical odor at Utah’s Hill Air Force Base.

The lieutenant was treated and released at a clinic Friday for a headache he thought might have been caused by hydrazine, which is commonly used in alternative fuels for F-16s.

A military spokesman says tests found no traces of hydrazine.

Initial reports said as many as 25 people may have been exposed to a chemical. Base spokesman Richard Essary says 25 civilian contractors were at the work site, but only one complained of symptoms.

The workers were digging a trench for fire hydrants in an industrial area of the base.

The cause of the reported odor remained under investigation late Friday.
