2.4.7 Electricity (overhead and underground)
If aerial tree works are contemplated within 10m (United Kingdom specific) of power lines (measuring the shortest distance between any parts of the tree and the power line), a risk-based approach must be adopted. In practice this will mean seeking specialist advice and guidance from the owner of the power line before undertaking any work within this distance.
Consideration must also be given to operations that are outside of this distance but have the potential to breach it.
If work is being carried out within 10m proximity to power lines, the basic principle will be to work with the electricity switched off and/or to establish (and maintain throughout the works) a measured safety or exclusion zone to/from the electrical apparatus.
Such arrangements will be set by, and agreed with, the owner of the power line.
Separate arrangements and competency levels exist for tree work contractors engaged directly by electricity companies that own or have responsibility for power lines.
Principal considerations relating to work in proximity to power lines are:
A) because of the different hazards posed, obligations in terms of managing the risks, staff training and competency requirements may differ;
B) the first choice for arborists when managing the risks from electricity should be to undertake the works with the lines de-energised;
C) any decision to undertake works with lines energised must be justified and documented;
D) all parties must be familiar with, and consider, any specific arrangements that the owner of the power line has in place. This may greatly impact upon safety distances and the use of access equipment on a given site;
E) all parties must be familiar with, and consider, both industry guidance and any manufacturer’s advice regarding the suitability, and use, of access or climbing equipment and tools near to power lines;
F) where arrangements have been made to work with the lines de-energised, it must be ensured work methods are used that avoid damage to the electrical equipment;
G) work planning must provide for appropriate levels of supervision and emergency procedures specific to the site and working methods selected.
I am shocked that no one is alarmed by this!!
Basically, I read this as stating that no W@H can be undertaken within 10m of ANY power line.
No mention of voltage.... LV / 400kV all treated the same. No differentiation between construction I.e. concentric service cable treated the same as bare 33kV
AND it doesn’t differentiate underground cables.
What is more, you get no real option of work method.
Basically what you do is speak to the power company and get them to isolate the offending networks, and you only cut once you have adequately demarcated the site.
ANY power line within 10m ( that’s 30 feet) of the nearest part of the tree.
This section decimates the opportunity to undertake front garden pruning and hedge trimming jobs in tens of thousands of streets up and down the country.
Sod ‘2 ropes’.... leave them in the truck!!, If this gets rigorously implemented, you don’t get cut trees in almost any suburban setting.
Where’s the outcry?
