RK-05: Battery Safety Pyramid

Framework RK-05v2.0July 2026Executive Brief

Battery Safety Pyramid

Five-layer safety architecture from supply chain to certification — the weakest layer defines the entire system.

Updated July 2026 · 5 Figures · For B2B Buyers, Engineers & Compliance Teams

Five-layer battery safety pyramid
Figure 1: Five-layer safety pyramid — 30-second visual overview. Supply Chain → Manufacturing → Cell → Pack Design → Certification. Each layer has 3–4 keywords. The pyramid is the entire page’s hero.

Safety failure chain diagram
Figure 2: Safety Failure Chain — left side shows how failures cascade through 5 stages. Right side shows the prevention at each stage. Every failure has a prevention if you design for it.

Risk reduction investment curves
Figure 3: Safety Investment vs Risk Reduction — 4 curves showing that early Safety-by-Design investment drops risk fastest. Late-stage fixes cost 10–50× more.

Five concentric validation layers
Figure 4: Five Layers of Validation — concentric rings from Material → Mechanical → Electrical → Environmental → Reliability. Each ring validates the one inside it.

Safety responsibility RACI matrix
Figure 5: Safety Responsibility Matrix — RACI-style (Responsible / Accountable / Consulted / Informed). No single party owns everything. Gaps in the RACI = gaps in safety.
