High levels of carbon monoxide found at industrial unit
UPDATE:
The cause of the carbon monoxide leak was found to be in a wire inside pipe insulation that had burned due to an electrical fault. The temperature in the pipe insulation was low so the wire did not cause a fire but was slowly decomposing creating carbon monoxide.
Firefighters remained at the scene until 8:45pm and left the scene in the care of the building occupier.
Firefighters were called to Motherwell Way, Grays, this afternoon after a number of people in an industrial unit felt unwell.
