RISK – Not communicating unexpected discoveries and harming protected species, artifacts or human health
Signs of contaminated soil may include discoloured or stained soil, an odour present and adverse impacts on plant life. If potential heritage artefacts or protected flora or fauna are discovered, isolate the area and seek professional advice.
- When undertaking clearing and earthworks, unexpected discoveries may occur. This can include:
- Heritage items such as scarred trees, shell middens and stone tools
- Protected plants and native animals
- Contaminated materials such as acid sulphate soils or asbestos
- If you think you have discovered something of heritage value, stop work and notify your supervisor. Barricade the area and do not disturb or remove any material.
- Do not recommence work until instructed by the authorised project representative
- If an animal is encountered during works, keep your distance and allow it to move out of the area on its own.
- If the animal is trapped or injured or if a nest is found, isolate the area and contact a qualified person to rescue or relocate the animal.
- Contamination may be detected through soil discolouration or odours.
- A qualified person must then test the soil to ensure it is safe to recommence work and advise of any handling, treatment and disposal requirements.
