Typical Activities: Possible Hazards : Safety Controls :
1. Locate existing
Services
Collision with vehicle,
communication, traffic,
noise
Potential to damage exiting
services
Disruption to water supply
Emissions from machinery
Prepare traffic management plan. Supply observer to assist Machine Operator. Warning Signs.
Consult authorities to identify required procedures for re-routing or temporarily taking offline services during works
Utilise all reasonable techniques for the advance location of existing services in the vicinity of the proposal, such as
advanced hand digging, location trough the use of metal detectors, ultrasound or otherwise
Contact Dial Before You Dig by dialing 1100 (or www.dialbeforeyoudig.com.au) to obtain copies of records of
services on the site. For a Sydney Water property obtain site plans / work as executed drawings from Property
Services.
Check at least 30M along the footpath in each direction and around nearby corners for indications of existing
services.
Carry out a service search by using pipe and cable location equipment.
Obtain permission from the gas company if excavating near a gas main (Sydney Water staff contact through
schedulers).
Obtain permission from Energy Australia or Integral Energy if excavating near a High Voltage cable.
Locate and mark underground services
DIG BY HAND SHOVEL (use only dry wooden handled or insulated tools) or non-destructive means to expose
ALL underground services within the immediate vicinity of the job to be performed. Look for warning tape and
conduits. Don’t use mechanical excavators until you have located and identified all services.
Have an appropriate fire extinguishing system available.
Have a person acting as an observer when using a mechanical excavator within 1M of an underground electricity
cable, optical fibre cable or gas main.
Locate and keep clear of overhead service (where applicable)
Instances where maintaining water supply is not possible, customers will be notified as per PH02 – Notification of
Residents
Machinery will not be left idling
Machinery will have appropriate exhaust emission controls

washed down in
stormwater drain
Possible damage tree roots
and subsequent damaging
trees
Bunding will be provided to stop materials washed down drainage.
Liaise with Local authorities for specific environment issues where applicable (Local EPA, RTA and council etc)

/ or pedestrians
Damage to property
Damage to trees and
vegetation
A traffic management plan will be implemented
Every care will be taken to avoid any property damage.
Be advised if large Tree roots are unearthed and a Tree preservation order application lodged.
Vegetated/sensitive areas will be fenced
All damaged property will be repaired by the end of the days work or as soon as possible
Signs advising of traffic changes/increased traffic will be displayed for both vehicles and pedestrians
