Insulators

Duties:

Insulators apply, remove and repair thermal and acoustical insulation (e.g., calcium silicate, glass foam, mineral wool, Styrofoam, fibreglass) on all types of industrial equipment (e.g., duct piping, heat exchangers, tanks, and vessels).

In general, insulators:

• Read and interpret drawings and specifications to determine insulation requirements

• Select the amount and type of insulation to be installed as well as a method of securing the insulation (e.g., spraying, pinwelding, wiring, pasting, strapping, taping) according to the type and shape of surface, whether or not the equipment is cold or hot, inside or outside, and what the equipment is going to be used for

• Measure and cut insulating material and coverings to the required shape and dimension

• Fit insulation around obstructions or shape insulation materials and protective coverings

• Install vapour barriers and finish insulated surfaces by applying metal cladding, canvas, plastic sheeting or cement

• Remove or seal off old asbestos insulation

Working Conditions:

Insulators work both indoors and outdoors, often in uncomfortable or potentially hazardous circumstances: in very hot or cold settings, on ladders or scaffolding, in cramped areas, with materials that are dusty, itchy or toxic. They must observe safety precautions and use equipment such as respirators, coveralls, and safety glasses/goggles.

Insulators usually work a 40-hour, five-day week but may work 40 hours in four days. Some overtime may be required to meet construction deadlines.
