2.24 Safety requirements <strong>in</strong> relation to lift<strong>in</strong>g and handl<strong>in</strong>g equipment.<br />
Safety requirements: static, mobile and overhead cranes, shear legs,<br />
pulley systems, sl<strong>in</strong>gs, jacks, crowbars, s<strong>in</strong>gle purchase w<strong>in</strong>ch, shift<strong>in</strong>g skates,<br />
mobile ramps<br />
2.25 Precautions to be observed when us<strong>in</strong>g scaffold platforms less than 2m high<br />
and <strong>in</strong> the use and transportation of ladders.<br />
Weld<strong>in</strong>g<br />
2.26 <strong>Basic</strong> pr<strong>in</strong>ciples of hard solder<strong>in</strong>g and braze weld<strong>in</strong>g.<br />
Pr<strong>in</strong>ciples: jo<strong>in</strong>t types and materials jo<strong>in</strong>ed, solders, fluxes, heat<strong>in</strong>g<br />
equipment, applications, safety precautions<br />
2.27 Methods used to protect the weld pool from atmospheric contam<strong>in</strong>ation<br />
dur<strong>in</strong>g weld<strong>in</strong>g.<br />
Protection: oxy – fuel gas, manual metal arc<br />
2.28 Oxy – fuel gas weld<strong>in</strong>g and ancillary equipment.<br />
Equipment: blow pipes, cyl<strong>in</strong>ders, filler metals and fluxes, pressure gauges,<br />
regulators, gas economiser, hose, connectors, protectors, safety devices,<br />
thread identification; hose, pipel<strong>in</strong>e and cyl<strong>in</strong>der colours, manifold system<br />
2.29 Oxy – fuel gas weld<strong>in</strong>g process.<br />
Process: sett<strong>in</strong>g up the equipment, leak test<strong>in</strong>g, oxy-fuel gas mix<strong>in</strong>g, flame<br />
adjustment (<strong>in</strong>clud<strong>in</strong>g oxidis<strong>in</strong>g, neutral and carburis<strong>in</strong>g flames), melt<strong>in</strong>g parent<br />
and filler metals, fusion and solidification, shutt<strong>in</strong>g down procedure<br />
2.30 Oxy – fuel gas cutt<strong>in</strong>g process.<br />
Process: exothermic reaction (ie metals cut, limitations), light<strong>in</strong>g, adjust<strong>in</strong>g<br />
and ext<strong>in</strong>guish<strong>in</strong>g the flame, factors <strong>in</strong>fluenc<strong>in</strong>g the quality of cut, applications,<br />
freehand cutt<strong>in</strong>g (ie cutt<strong>in</strong>g from an edge of plate, <strong>in</strong>side from the edge,<br />
sections, round bar), guided hand cutt<strong>in</strong>g (ie bevel cutt<strong>in</strong>g, circle cutt<strong>in</strong>g guides,<br />
spade or wheel guides)<br />
2.31 Oxy-fuel gas cutt<strong>in</strong>g and ancillary equipment.<br />
Equipment: blow pipes (eg arrangements of the mix<strong>in</strong>g of oxygen and fuel<br />
gas), construction and application of typical cutt<strong>in</strong>g nozzles, hoses (eg<br />
connections, safety devices, identification), pressure gauges and regulators,<br />
gases (eg acetylene, propane, hydrogen, oxygen) flame temperature, relative<br />
cutt<strong>in</strong>g speed, operat<strong>in</strong>g costs, cyl<strong>in</strong>der identification<br />
2.32 Potential safety hazards associated with oxyfuel gas weld<strong>in</strong>g and cutt<strong>in</strong>g and<br />
precautions which should be taken.<br />
2.33 Manual metal arc weld<strong>in</strong>g power sources.<br />
