Digital Hazardous Energy Isolation for Faster LOTO Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety procedures for hazardous energy control in industries are time-consuming and prone to human error, particularly in managing and documenting the isolation of electrical energy sources, which is a leading cause of construction-related injuries.
Innovation Solution
A web-based application that allows users to manage worksites, conduct lockout/tagout (LOTO) processes, and track equipment safety through personalized profiles, scan functions, and automated verification processes, ensuring accurate and efficient isolation of hazardous energy sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual paper logbooks and manual updating of electrical one-line drawings are used, then the system is simple to implement, but the process is time-consuming and subject to human error
Solution Approach 1:
The patent replaces manual mechanical processes (paper logbooks, hand-drawn one-line drawings) with an automated electronic system that uses mobile devices, databases, and software applications to document energy sources and track LOTO procedures, eliminating manual data entry and reducing human error
Solution Approach 2:
The patent creates digital copies of traditional paper-based documentation systems through electronic databases and mobile applications that store and display energy source information, equipment status, and LOTO procedure details, allowing rapid access and updating without physical paperwork
2Reliability
If comprehensive manual verification procedures are implemented, then safety is improved, but the process becomes more time-consuming
Solution Approach 1:
The patent implements automated feedback mechanisms where the system provides real-time verification prompts, status updates, and confirmation requirements to users during LOTO procedures, ensuring safety checks are completed while streamlining the verification process through structured digital workflows
Solution Approach 2:
The patent performs preliminary actions by pre-configuring energy source databases, pre-identifying isolation points, and pre-establishing LOTO procedure templates before actual maintenance work begins, allowing rapid execution of safety procedures without time-consuming on-site analysis
