Surface Fall of Persons
A welder for a surface construction company was injured recently
when he fell into thermal dryer cyclone unit. The injured,
equipped with a full body harness and lanyard, entered the
pressure relief door of the cyclone to clean coal fines from the
top of the cyclone unit and to install a work deck over the
cyclone opening in advance of welding repairs to the door and
connecting duct work.
After some initial cleaning, the injured man handed his
lanyard to a coworker, preparing to reposition himself. Suddenly,
the injured slipped and fell headlong into the cyclone unit. The
injured worker was extricated from the cyclone with the use of a
mobile crane. He was transported to a hospital via ambulance
where he received treatment for a head laceration.
