# Prepare to report serious incidents with high-risk AI

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [AI Act](https://agentwranglers.se/playbook/compliance/ai-act.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

- ID: CMP-87
- Level: Recommended
- Chapter: [AI Act](https://agentwranglers.se/playbook/compliance/ai-act.md)
- Rule: If you provide a high-risk AI system, add the AI Act's serious incident deadlines to your incident tool before the high-risk duties start. Name who reports to which authority.
- Check: A unit test opens an incident flagged `ai_act` and `death` with awareness on 1 March 2028. The tool shows the report due on 11 March 2028. The obligations register names the authority and two people who can report.
- Applies when: The project uses AI models.
- Region: European Union (EU). The duty comes from the law there. The rule applies only when the project serves people there, and its Applies when also holds.
- Review by: 2027-06-30
- How: AI Act Article 73 makes providers report a serious incident to the market surveillance authority where it happened. The report is due within 15 days of learning of it, within 10 days after a death, and within 2 days for a widespread incident. The 2-day limit also covers an incident that disrupts critical infrastructure. A serious incident includes death or serious harm to health, serious harm to property or the environment, and a breach of fundamental rights. Compute the dates with the other clocks, as [Start every reporting clock from one moment](https://agentwranglers.se/playbook/compliance/breaches-and-reporting/reporting-clocks.md) says. The start date follows the high-risk duties in [Find out if a feature is high-risk](https://agentwranglers.se/playbook/compliance/ai-act/ai-high-risk-check.md).
