According to Millbury Fire Chief Richard Hamilton, the furnace was turned off so the men could do the routine cleaning but their equipment malfunctioned.

“You can imagine what window washers use on a high rise, that’s exactly what they had. One cable was good, the other one jammed,” said Hamilton.
