• Has a documented risk assessment been conducted to identify, assess and manage the hazards present (eg SWMS, JHA)?

  Yes

  No

  N/A

• If required, documented evidence that a structural or geotechnical engineer has been consulted in planning or assessing the excavation?

  Yes

  No

  N/A

• A permit has been correctly completed and is available for the personnel undertaking the work.

  Yes

  No

  N/A

• Service Identification has been completed , services marked up on drawings, all available drawings are attached to the permit and up-to-date, as built / survey data included where available.

  Yes

  No

• The non-destructive excavation process is in use and is followed.

  Yes

  No

  N/A

• Check the items that do not conform to the process correctly.

  Select

• Evidence is available of services being de-energised (PTW for isolations) and LOTO processes in place (where possible).

  Yes

  No

  N/A

• Method of protecting services from mechanical damage is known and documented by the work crew prior to commencing.

  Yes

  No

  N/A

• Safe approach distances to underground and overhead services have been determined, are known, and complied with.

  Yes

  No

  N/A

9.3 Excavation zone - Have exclusion zones, barriers, lighting, signage, etc been selected, installed, and maintained.

• Spoil distance from an excavation is equal or greater than the depth.

  Yes

  No

  N/A

  Yes

  No

  N/A

• Stop work, and remove personnel from the excavation until safe access has been completed.

• Physical edge protection and signage are established around the excavations / penetrations to prevent unplanned access.

  Yes

  No

  N/A

• When the need to enter excavations or penetrations is required, have a safe means of access / egress been established?

  Yes

  No

  N/A

  Yes

  No

  N/A

• Controls have been put in place to ensure materials and plant are not stacked or placed near the edge of the excavation or inside the zone of influence. Distance set back determined by a qualified engineer and included in risk assessment.

  Yes

  No

  N/A

9.5 Confined Spaces

• Evidence that the excavation has been assessed and tested to identify potentially hazardous atmosphere and presence of hazards associated with confined spaces.

  Yes

  No

  N/A

• Stop the work until made safe to enter.
