Event description

Five employees exposed to MEK vapors

Investigation abstract

On February 20, 1990, three employees were sent to the hospital after suffering symptoms of overexposure to methyl ethyl ketone (MEK) in a closed area with reci rculated air. There was no exhaust to pull out the vapors at the work stations. The problem was thought to have been resolved by introducing fresh air instead o f recirculated air; however, no exhaust was provided. Five employees were sent t o the hospital for their exposure to the MEK vapors. One employee passed out on the way to the medical facility. No employees were hospitalized.
