Range of VariablesThe Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available |
What tools and equipment are likely to be used when installing metal structures and features? | Tools and equipment may include levelling equipment, string lines, tape measures, marking gauges, spades, shovels, crow bars, hammers, spanners, metal files, hacksaws, angle grinders and electric saws with metal blades. |
What OHS hazards may apply to this standard? | OHS hazards may include manual lifting, use of power tools, use of sharp hand tools, dust, and sun exposure. |
What OHS controls may be relevant to this standard? | OHS controls may include safe lifting and transporting techniques, the appropriate use of personal protective clothing and equipment such as overalls, boots, face shield, hat, installation of safety signs and barriers, the disabling and disconnecting of soldering, thermal cutting equipment and other powered tools when not in use, the identification of site access points, the safe storage of materials on site, the drinking of fluids, and basic first aid. |
What environmental implications are likely to be considered? | Consideration may be given to the impact of soil disturbance and the alteration to water flow during construction and after the structure or feature has been installed. |
What services are likely to be located on site? | Services may include power, gas, water, stormwater, sewerage or septic connections, phone and optical cables. |
What type of footings are likely to be prepared for metal structures and features? | Footings may be concrete or in some case rammed earth. The depth of footings and timing of footing installation may vary according to the type of structure or feature to be installed. Some structures (e.g. fences) need the post and footing installed at the beginning. Others may be supported by temporary bracing, and when complete, the footings are filled. |
What metal components are likely to be included in a timber structure or feature? | Metal components may include panels, sheets, posts, bars, rails, wire, wire mesh and metal lattice. |
What cutting tools are likely to be used? | Cutting tools may include hacksaws, angle grinders, electric saws with metal blades, and thermal cutting equipment (oxy acetylene set). |
What OHS specifications may be included for the use of metal cutting equipment? | OHS specifications may include pre start checks of blades, torches, irons, nuts, bolts and switches, operating the equipment according to manufacturers recommendations including correct handling, the wearing of protective clothing and eye protection, and regular servicing and safe storage when not in use. |
What methods are likely to be used for joining metal to metal? | Joining methods may include brackets, nuts and bolts, hinges, and other metal screws and fasteners. |
How can metal components be fixed into place? | Metal fixing methods may include brackets, galvanised plates, saddles, nails, cuphead bolts, coach screws, and masonry bolts. |
How can a structure or feature be finished off to ensure completeness and security of components? | Finishing off may include the cutting off of overhangs, burring of angles and edges, and any other cosmetic work that may be required. |
What coatings are likely to be applied to metal structures and features? | Coatings may include primers and paint with rust inhibitors. |
What OHS guidelines are likely to be followed when applying coatings to metal? | Guidelines may include appropriate personal protective clothing and equipment, protective ground cloths, preparing and applying the coating according to manufacturers recommendations, correct care and cleaning of application tools, the installation of "wet surface" signs and barriers, and the disposal of empty containers in an environmentally safe and sensitive manner. |
