Fall of Face, Rib, Side or Highwall

Fall of Face, Rib, Side or Highwall. The danger was already part of the wall. Look for the warning condition, the exposed roles, and the moment when a normal task becomes an abnormal situation. Experienced operators do not wait for certainty when the consequence can grow faster than the information. Pause, communicate, protect the exposure, and follow the approved site procedure before work continues.

Fall of Face, Rib, Side or Highwall is presented as a decision situation. The card holds on the warning moment so a learner can notice changing conditions, identify exposed people and equipment, and choose the next safe action before escalation.

The value is not spectacle or hindsight. It is learning to recognize how geotech risk develops in surface + underground work, then connecting that recognition to role-specific communication, isolation, withdrawal and escalation.

1. Withdraw from the exposure area and protect the exclusion zone.
2. Escalate the observed change to the geotechnical and operating authorities.
3. Check current monitoring, inspection and trigger-action requirements for the site.
4. Resume only under the approved site plan and competent authorization.

Potential consequences vary by site and task. This preview avoids invented tolls, probabilities and causal certainty; approved sources and local procedures govern.
