  Yes

  No

  N/A

• Ensure that structures are well designed and maintained as per requirements. Quality control and assurance must be given on welded structures.

  Yes

  No

  N/A

• Adhere to legal legislation and in-country standards with regards to all structures.

  Yes

  No

  N/A

• Conduct structural surveys or reports as required.

  Yes

  No

  N/A

• Issue a Permit to Work before structural work commences.

  Yes

  No

  N/A

• Refer to the Working around liquid bodies, Working at heights, Confined space and/or High-risk machinery risk category standards if the work includes anything relevant to these.

  Yes

  No

  N/A

Adhere to Structural Design

• All structures to be designed and approved by registered professionals.

  Yes

  No

  N/A

• Ensure the material of construction is correct to ensure structural integrity throughout the lifespan of the structure (e.g. prevent rapid corrosion and failure).

  Yes

  No

  N/A

• Conduct recognised integrity inspections and testing(e.g. non-destructible tests (NDT)) where required.

  Yes

  No

  N/A

• Provide indications of safe structural load limits (e.g. signage) as far as reasonably possible.

  Yes

  No

  N/A

• Do not overload any structure, adhere to safe working load capacities.

  Yes

  No

  N/A

• Conduct a structural survey to confirm load bearing of structures as required, also when changes or additions are made to structures or new structures are added.

  Yes

  No

  N/A

• All changes to structures must be subject to an MOC and approvals process.

  Yes

  No

  N/A

Requirements for Specific Structures:

• Special scaffold structures must be structurally sound for the intended use and built to the relevant in-country regulations and/or standards.

  Yes

  No

• For man-made dams (e.g. ash dams): Maintain the freeboard requirements (area between the flood level and crest of dam). The capacities of the dams must not be exceeded

  Yes

  No

• Dam walls should have filter drains to capture seepage moving through<br>the ash walling and prevent structural failures.

  Yes

  No

Structural Integrity Inspections

• Structures must be inspected regularly by a competent person or registered professional according to in-country regulations.

  Yes

  No

  N/A

• Inspect all materials before construction and thereafter. Inspect the completed structure at pre-determined intervals and after adverse weather events by the competent person.

  Yes

  No

  N/A

• For any dams: Conduct stability analysis of the dam walls by the registered professional

  Yes

  No

  N/A

• For any dams: rly inspect the dam or other catchment lining to prevent underground<br>water pollution.

  Yes

  No

  N/A

• For any dams: Inspection to include checking for blockages on the penstock to avoid liquid build up in ash dams.

  Yes

  No
