Boilermakers fabricate, assemble, erect, test, maintain and repair boilers, vessels, tanks, towers, heat exchangers and other heavy-metal structures. They are employed in boiler fabrication, manufacturing, shipbuilding, construction, electric power generation and similar industrial establishments.
Construction boilermakers assemble and repair mammoth boilers, blast furnaces, pressure vessels, and power generating storage tanks. The size of these tanks means that they often work at great heights. Construction boilermakers work with hand and power tools. They often work in cramped, noisy conditions and can be exposed to chemical vapours.
