Abstract
In most cases, a
refractory repair involves dealing with used refractory linings above shoulder
height, defining these as overhead refractories. This paper details a method of
personnel protection involving a low-pressure inflatable balloon system,
installed to prevent the dislodgement and freefall of in-situ refractories. This
system has been successfully applied to numerous types of vessels in the process
industries in the last three to four years. This paper, prepared for the CIM
Conference of Metallurgists held in Vancouver, British Columbia in October 2010,
outlines details of the system and gives examples of successful
applications.
