The excavation has a safe means of access and egress.
-
Procedure that identifies the means for ensuring safe access and egress to an excavation.
-
Project risk assessment and relevant SWMS/JSAs outline means for ensuring safe means of access and egress to and from excavation.
-
The shoring/battering is designed by a suitably qualified person and there are relevant drawings indicating the method used
-
A procedure that identifies the means for controlling ground stability associated with excavations on the project and where shoring, benching or battering is employed, that it shall be designed by a registered professional engineer (geo-technical).
-
Project risk assessment and relevant SWMS/JSAs identify and assess the risk of collapse and outline the means for ensuring stability of excavation.
-
Drawing for shoring and/or benching/battering design exist.
-
Engineering certification.
-
Shoring installations instructions.
-
The trench is regularly inspected by a competent person to ensure controls are used and remain adequate.
-
A procedure that identifies competency requirements and outlines a requirement and methodology to perform inspection of excavation on a regular basis, as determined by qualified assessment.
-
Inspection records.
-
Barriers, signage and fencing have been established in and around the trench.
-
A procedure that identifies a process for ensuring adequate isolation and prevention of access to an excavation consistent with jurisdictional legislation, codes and standards.
-
Project risk assessment and relevant SWMS/JSAs identify and assess risk of falling into a trench/excavation and outline means for preventing access with consideration of excavation depth and location of site.<br>EG: May be reduced risk in remote location. ````````````````````````````````````
-
Warning signage and placards are installed and consistent with relevant legislation, standards and codes.
-
Self supporting barricades/barriers and/or fencing are installed around the perimeter of the excavation that are at least 900mm high
-
Self supporting barricades/barriers and/or fencing which are not capable of or designed as edge protection must be set back a distance from the edge of the trench or excavation.
-
In some circumstances some barries and/or fencing may need to be suitable to prevent access to the public and thus may include 1800mm high hoarding or fencing in urban areas.
-
Above ground and underground services have been identified and made safe
-
A procedure that identifies a process for identigying services that could be contacted with during course of excavation and/or site access.
-
Project risk assessment and relevant SWMS identify and assess risk of contacted above ground and under ground servces and outline means for preventing contact with services.
-
Electricial and service exclusion zones have been identified, communicated and maintained on the project site in accordance with jurisdictional requirements.
-
Non mechanical excavation means are utilised on the site when necessary
-
Services detection reports and diagrams
-
Services locations and depths are identified and locations marked on the project site.
-
Signage and placecards are erected in locations to warn workers of services.
-
Physical barriers are installed to prevent inadvertent contact with services.
-
Lock out and tag oug procedures and processes.
-
Approval and records of disconnection from services entity.
-
The confined space aspect have been suitably identified, controlled and are continually monitored.
-
The project risk assessment and relevant SWMS may identify confined space aspects of excavation where relevant and outline measures consisten with documented confined space procedures and processes.
-
Inspection records.
-
Records of atmospheric monitoring.
-
Confined space permit records.
-
Confined space entry register and warning signage.
-
The risks involved with mobile plant working in and around the excavation have been assessed and controlled.
-
The project risk assessment and relevant SWMS identifies and assesses risk of mobile plant operating in the vinicity to open excavations and outlines control measures consistent with relevant standards and codes.
-
Vehicle and mobile plant are prevented from encroaching excavation zone of influence unless designed to accommodate load
-
Warnings and physical barriers are erected to prevent inabvertent collapse of excavation or plant entry into open excavations.
-
The safety of the surrounding structures and areas has been assessed.
-
A procedure or similar document that identifies a process for ensuring geo-technical assessment ot determine potential impact onsurrounding structures and areas.
-
Written geo-technical advice and reports
-
The project risk assessment and relevant SWMS identify risks to surrounding structures and areas during excavation (where relevant) and outline control measures consistent with engineering advice.
-
Where applicable, temporary supports have been designed and installed in accordance with applicable standards arid codes.
-
Emergency procedures have been established for the excavation
-
An emergency plan or response protocol that defines potential emergency scenarios associated with an excavation on the porject. Scenarios mush be relecant to site risks and may include (but no limited to):<br>- Flooding and water ingress<br>- Contact with hazardous services including electrical and gas<br>- Stability and collapse of excavation<br>- Fall from heights<br>- Confined space and retrieval<br>- Mobile plant rollover.
-
Drill records of excavation related emergency response scenarios.
-
Workers within the excavation are adequately trained and instructed and are aware of the emergency procedures.
-
A procedure that identifies a requirement to ensure emergency response procedures have been communicated to workers and trained and instructed in response protocols
-
Excavation workers are aware of appliccable emergency response protocols.
-
Training records.
-
Toolbox and other communication records.
-
Possible water source have been identified and control measures implemented to remove the risk of flooding and/or engulfment due to water infused soil instability.
-
A procedure identifies a process for identifying and controlling potential risk of water engulfment within excavations.
-
Geo-technical review shall identify and assess the risk of rising, irruption or inrush of water.
-
Control measures to provent flooding and/or provide early warnings of flooding risk have been implemented on the project e.g. membranes, sumps, exploratory warnings holes, lowering water table etc.
