Contactless PPE Compliance Check at Electrical Enclosures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers often neglect or forget to wear adequate personal protective equipment (PPE) when working with electrical enclosures, leading to potential arc flash hazards due to time pressure or lack of safety culture, resulting in injuries.
Innovation Solution
A method and system for contact-less scanning and evaluation of PPE next to an electrical enclosure, comparing the scanned information with specific requirements and providing feedback to ensure compliance, using optical detectors or RFID readers, and optionally involving unmanned autonomous vehicles to deliver missing PPE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers are provided with safety protocols specifying PPE, then safety protection is improved, but compliance is worsened due to time pressure and lack of safety culture
Solution Approach 1:
The system provides real-time feedback to workers about their PPE compliance status through visual indicators (green/red lights) and audio signals. The feedback unit communicates whether the worker is properly equipped before allowing access to the electrical enclosure, creating immediate awareness and encouraging compliance without requiring manual checking or memory of protocols.
Solution Approach 2:
The system enables workers to self-verify their PPE compliance through automatic detection. The scanning unit automatically identifies the worker and checks their equipment status without requiring them to manually check mirrors or remember protocols. The system serves the worker by automatically performing the compliance verification that would otherwise require their active participation and attention.
2Ease of operation
If manual PPE checking is used, then compliance monitoring is improved, but time consumption and reliability are worsened
Solution Approach 1:
The system replaces manual mechanical checking processes with automated optical and RFID scanning technology. Instead of workers manually checking mirrors or supervisors physically inspecting PPE, the scanning unit uses optical detectors and RFID readers to automatically identify and verify equipment. This substitution eliminates the time-consuming manual verification process while maintaining comprehensive compliance monitoring.
Solution Approach 2:
The system introduces an intermediary automated scanning system between the worker and the compliance verification process. Rather than direct manual inspection, the scanning unit acts as an intermediary that automatically detects PPE status and communicates it to the feedback unit, streamlining the verification process and eliminating delays associated with manual checking.
3Extent of automation
If automated scanning systems are deployed, then compliance control is improved, but device complexity is worsened
Solution Approach 1:
The scanning unit is designed as a multi-functional device that performs multiple tasks: optical scanning to detect PPE presence, RFID reading to verify equipment authenticity, worker identification, and data communication with the feedback unit. By consolidating these functions into a single universal device rather than separate specialized components, the system achieves high automation while managing complexity through functional integration.

AI summary
The present disclosure relates to a method for controlling personal protective equipment. The method comprises positioning of a person (120) equipped with personal protective equipment (122) next to an electrical enclosure (110), wherein a specific personal protective equipment requirement (112) is defined for the electrical enclosure. The method further comprises scanning the personal protective equipment in a contact-less manner while the person is next to the electrical enclosure. Thereby scanned personal protective equipment information (132) are generated. The method further comprises comparing the scanned personal protective equipment information with the specific personal protective equipment requirement and evaluating, based on the comparison, whether the personal protective equipment is in accordance with the specific personal protective equipment requirement. The method further comprises providing a feedback indicating whether or not the personal protective equipment is in accordance with the specific personal protective equipment requirement.
