High-Risk LOTO Control System
Target Audience: VP of Safety, Chief Compliance Officer (CCO), Director of Maintenance
Core Value: Mitigate Fatality Risk & Ensure Regulatory Audit Readiness
The Problem: The "Catastrophic Liability Trap"
Unscheduled machine maintenance and high-risk LOTO (Lockout/Tagout) procedures relied on unreliable paper checklists and single-user sign-offs, creating severe injury risk.
The Solution: Secure Digital LOTO Audit Trail
I architected the Digital Lockout/Tagout (LOTO) State Machine, enforcing multi-user, time-stamped digital confirmation and establishing a secure, immutable audit trail for all high-risk procedures.
The Commercial ROI
P&L Hook: Mitigated severe injury liability exposure and reduced associated insurance risk by enforcing procedural adherence.
Primary Metric: Ensured 100% verifiable adherence to high-risk maintenance procedures, making the operation instantly audit-ready.
Value Proposition: Eliminated dependency on unreliable paper-based LOTO checklists, thereby lowering potential OSHA fines and liability premiums.
Technical Architecture
Logic: Implemented a Digital LOTO State Machine that strictly controls asset status (Safe -> Serviced -> Operational).
Integrity: Required multi-user, time-stamped Cryptographic Digital Signature/Confirmation from maintenance personnel via a mobile UI.
Enforcement: Architected the system to block the Digital Twin asset status from moving to 'Operational' until all mandatory sign-off procedures were logged.
