The men worked for CTEH, a firm that consults with businesses, communities and governments on current and potential environmental threats.

The company’s website said Kendrick, 41, was a safety supervisor with experience in conducting real-time air monitoring during chemical release responses, among many other things.

Bennett, a 36-year-old staffing manager with a focus on logistics, has experience responding to crude oil releases, train derailments, chemical spills and other emergency responses, CTEH’s website said.

CTEH said in an email on Thursday that Beaty, 23, was a production safety data manager; Walker, 32, was a rapid responder; and Sweeney, 64, was the pilot.

A company spokesman told The Associated Press that employees on the plane, including the pilot, were on their way to an explosion at a Cleveland-area metals plant this week that killed one worker and sent over a dozen more to the hospital.

CTEH did not comment further to Fox News Digital.
