C1 - operation near aerial conductors (overhead power lines)
“Reproduced from as2550.1”
C1-1 general
This clause refers to hazards and risks presented by the set-up and operation of the platform in the vicinity of overhead
electrical conductors.
Notes:
1 Electricity supply bodies in each state may have issued guidelines for the use of platforms and other plant in the
vicinity of overhead conductors; for example, the electricity association of new south wales’ publication ‘interim guide for
operating platforms and plant in proximity to overhead power lines’.
2 A conservative approach has been adopted. Separation distances have not been chosen based purely on electrical
voltages of conductors, nor whether the conductor is bare or insulated.
The distances were chosen based on experience and practical considerations, since platforms cannot be operated
as accurately as arcing distances can be calculated.
Before operating the platform from the stowed condition, a check for the presence of overhead conductors and power lines shall
be undertaken.
Throughout clause a, the following definitions apply:
(a) aerial conductor—an overhead conductor that is either insulated or bare.
(b) Operation—where any platform components are moved or about to be moved from their stowed position.
(c) Overhead power line—aerial conductors and other parts that make up an aerial line for the distribution and
transmission of electrical energy.
(d) Electricity distributor—the power supply authority, transmission line operator, generator, traction company
or distribution company.
All aerial conductors shall be treated as alive unless the platform operator has received, from the electricity distributor or
transmission line operator, documentary evidence that the conductors have been positively de-energized, isolated and earthed.
Where such documentary evidence has been made available, it shall state the date and time frame of isolation and any special
conditions and precautions. The platform shall not be operated in contravention of this documentary information.
C1-2 Precautions when operating near live aerial conductors
The platform shall only be operated within close proximity of live aerial conductors, if the separation distances appropriate to the
‘NO-GO-ZONE’ or ‘SPOTTER-REQUIREDZONE’, and risk controls given in Clause C1.3, are maintained.
A site-specific risk assessment shall be completed before the commencement of the job by a trained and competent person.
This assessment shall be verified immediately before work commences, and its relevance monitored during the job. If initial
associated circumstances change, work shall cease until an appropriate risk assessment is undertaken.
Where a spotter is required to inform the operator in the event of the platform approaching the zone boundaries shown, the
following applies:
(a) The spotting operation shall be carried out by a competent person.
NOTE: Required competency levels may be defined by the Office of the Chief Electrical Inspector or similar body in the
applicable State.
(b) The spotter shall be positioned so as to minimize the risk of exposure to hazards.
(c) The spotter shall be able to clearly observe the separation distances.
(d) The spotter shall not undertake any other work whilst performing spotting duties.
(e) The spotter shall be specifically instructed in the workplace hazards applicable to the site.
(f) The spotter shall be able to communicate with the platform operator at all times during erection, operation
and dismantling.
