- Assess slope stability before allowing anyone to work at or below a slope.
- Design temporary slopes based on geotechnical advice for the conditions.
- Keep stockpiles at least 1 metre back from excavation and slope edges.
- Monitor slopes daily for cracks, bulging, water seepage, or movement.
- Reduce slope angles or install support if water content increases.
- Keep heavy plant away from the crest of temporary slopes.
- Install drainage to divert surface water away from slope faces.
- Re-assess slopes after heavy rainfall, freeze-thaw, or vibration.
- Brief operatives on signs of impending slope failure.
- Stop work and evacuate if slope movement or cracking is observed.

- DON'T work at the base of an unassessed or unsupported steep slope.
- DON'T park heavy plant or stack materials at the top of a slope.
- DON'T assume a slope is stable because it has been standing for days.
- DON'T excavate into the toe of a slope without engineering assessment.
- DON'T ignore cracks, tension lines, or water seepage on a slope face.
- DON'T stockpile excavated material at the edge of an excavation.
- DON'T continue earthworks during heavy rainfall without reassessing.
- DON'T allow water to pond at the crest of a temporary slope.
- DON'T remove vegetation from slopes without considering stability impact.
- DON'T undercut slopes to create extra space without approval.
