ERS Safety Principles
Chapter: C5
In Simple Terms
F1 cars must be designed so that a single electrical failure cannot expose drivers or others to dangerous electrical parts. All ERS components must be safe under normal driving and even if something breaks unexpectedly.
- Single point of failure protection: One broken part cannot create electrical hazards
- Safety under all conditions: Components must be safe during normal operation and reasonably foreseeable malfunctions
- No live part exposure: Drivers and personnel cannot contact dangerous electrical components in any scenario
- Comprehensive component safety: All ERS parts must be designed to prevent injury in any circumstance
Official FIA Text
