Thermal and Electrical Hazard Prioritization & Residual Risk Mitigation
An electro medical device manufacturer producing a high frequency electrosurgical generator and radiofrequency tissue ablation workstation.
Run on Tatvam · Design Risk & FMEA
The challenge
The device delivered high energy RF currents, creating severe thermal injury, capacitive coupling, and electromagnetic interference (EMI) hazards.
Engineers struggled to quantify whether combined risk mitigations reduced the residual patient risk to an acceptable level per ALARP (As Low As Reasonably Practicable) criteria.
Subjective risk scoring in spreadsheets led to prolonged debates between R&D; engineers and Quality Assurance directors, stalling design freezes.
How Tatvam solves it
Energy Hazard & Biophysical Modeling
Tatvam categorizes thermal, electrical, radiation, and biological hazards into structured hazard tree hierarchies.
Pre Mitigation vs Post Mitigation Risk Tracking
Tracks initial risk scores alongside residual risk ratings after applying hardware safety interlocks and software watchdogs.
Objective ALARP Evaluation Dashboard
Provides clear visual risk matrices displaying pre mitigation and post mitigation hazard distributions objectively.
Clinical Benefit vs Risk Ratio Analysis
Synthesizes clinical trial evidence and hazard probability models to generate defensible Benefit Risk Analysis (BRA) documentation.
Quality Assurance Approval Workflows
Enforces mandatory cryptographic sign offs from Lead System Architects and Quality Directors before residual risks are accepted.
The outcome
- residual risk evaluation and design freeze sign off accelerated
- 0 weeksresidual risk evaluation and design freeze sign off accelerated
- high severity thermal and electrical hazards mitigated
- 0%high severity thermal and electrical hazards mitigated
Residual risk evaluation and design freeze sign off accelerated from 6 weeks to 4 business days.
100% of high severity thermal and electrical hazards mitigated to verified acceptable ALARP levels.
Zero design modifications required during external IEC 60601 1 medical electrical safety testing.

Capabilities used
Every accelerator is assembled from the same capability layer, so a workflow you adopt here shares its foundation with the rest of the portfolio.
