Post-Incident Testing Steps for UK Construction Sites

1. Stabilise and secure the environment

Prioritise immediate safety controls, isolate hazards, and ensure injured persons receive appropriate response.

2. Trigger policy-aligned escalation

Notify designated managers and HR contacts according to your post-incident pathway and incident category rules.

3. Record facts before assumptions

Capture time, location, involved roles, witness details, and observable indicators while information is still reliable.

4. Arrange testing without delay

Use your agreed testing route and chain-of-custody procedure so collection and reporting remain defensible.

5. Keep communication confidential

Share only with authorised stakeholders and avoid informal commentary that could prejudice follow-up decisions.

6. Close with documented next steps

Track follow-up actions, policy outcomes, and improvement measures for governance and future incident learning.
