Task F-17 Installs and maintains refractories

Task descriptor

Refractories are used in various settings such as refineries, pulp mills, steel mills, crematoriums and incinerators. Refractory materials are used to contain the burning process and retain or refract heat. Refractory materials are selected according to criteria such as ease of installation, cost effectiveness and durability. The skills involved in installing refractories encompass many of the general masonry skills as well as specialized knowledge of these materials and applications. Due to the use of products containing refractory ceramic fibres (RCFs) and the need to work in confined spaces, maintaining personal safety is paramount.
