2.1 General
To erect, alter and dismantle scaffolding correctly. safely and efficiently, a competent person should have the following knowledge and skills:
(a) Be able to read and understand the supplier’s information, general site plans, design drawings and specifications for scaffolds.
NOTE An ability to make simple calculations of dead load and live load maybe needed.
(b) Have a thorough knowledge of the scaffolding equipment including the identification of the system being used.
NOTE The use of uncertified and untested scaffold system combinations should be avoided.
(c) Have thorough knowledge of the construction methods and design requirements associated with that equipment.
(d) Be able to recognize common hazards at the worksite and be capable of taking effective precautions to control risks to health and safety arising from these hazards.
(e) Visually inspect scaffolding equipment for faults.
(f) Have the physical skills needed for scaffolding construction.
(g) Be competent in manual lifting techniques.
(h) Work safely and confidently at heights.
(i) Correctly use the various tools, ropes and gin wheels.
(j) Erect and dismantle scaffolding in the correct sequence.
2.2 Information from regulatory authorities
Refer to the relevant regulatory authority for information about scaffold registration and licensing requirements.
3.1 Identification of hazards
Hazards commonly associated with scaffolding include the following:
(a) Engaging in the erection and dismantling of a scaffold or access equipment.
(b) Working over water.
(c) Falls from heights.
(d) Falling objects.
(e) Manual handling.
(f) Electricity.
Corrosive substances.
(h) Volatile atmospheres.
(I) Movement of cranes, vehicles and machinery.
(j) Weak or unstable supporting structures or unsuitable ground conditions.
(k) Stacking of equipment in unstable conditions.
(I) High winds and storms.
(m) Proximity to sources of radiation (e.g. mobile phone towers).
(n) Potential flammability of encapsulation.
3.2 Proximity to power lines
Power lines are a potential hazard to persons erecting, working from or in the vicinity of a scaffold.
Contact the electricity supply authority for information before erecting, using and dismantling scaffolding in close proximity to power lines. For voltages of 11kV or less ‘close proximity is typically a minimum clearance of 4 m between power lines and the adjacent scaffolding but may vary depending on electricity supply authority requirements (see Figure 3.2(A)).
The fitting of non-conductive materials on the outer face of the scaffold adjacent to power lines may be required by the electricity supply authority (see Figure 3.2(B)).
Metallic fixings should not protrude through the face of the non-conductive material towards the powerlines.AS 4576 pdf download.
