Summary
An engineer aboard a cruise ship suffered severe facial scalding after opening an isolated economiser’s drain valve before cooling was complete. Hot water and steam discharged and deflected upwards from a tundish. The flash highlights discharge-path exposure, caution when opening pressurised drain lines, and controlled valve operation using a correctly sized wheel key.
