Digitalizing Lock Out, Tag Out (LOTO): Transforming Safety in Construction

Transforming high-stakes safety procedures through user-centered research

The Product: A digital transformation of the Lock Out, Tag Out (LOTO) process—a highly regulated safety procedure critical for de-energizing equipment during construction maintenance. This project tackled the inefficiencies of traditional paper-based LOTO, aiming to digitize the workflow without compromising safety or compliance.

My Role: Lead UX Researcher—spearheading all user research initiatives from understanding complex workflows to validating proposed solutions, ensuring the digital transformation was deeply rooted in user needs and operational realities.

Key Outcome: 30% increase in permit handling efficiency, improved compliance, enhanced user satisfaction, and an estimated $300K saved annually in fines, administrative costs, and avoided downtime.

The Challenge

Manual Process, High Stakes

The traditional paper-based LOTO system was fraught with inefficiencies, manual errors, and communication gaps. Complex documentation, labor-intensive coordination, and frequent "temporary lifts" for testing created bottlenecks and increased the risk of non-compliance and safety incidents.

Critical Pain Points:

  • Project Engineers spending excessive time on error correction

  • Potential financial losses from inefficiencies

  • Reduced focus on critical safety responsibilities

  • High risk of non-compliance with OSHA standards

The Solution

Digitalizing for Safety & Efficiency

Our solution digitalized the entire LOTO process to streamline authorization, improve record-keeping, and facilitate seamless communication.

Goals:

  • Enhance Safety & Compliance: Reduce manual errors and ensure adherence to OSHA 29 CFR 1910.147

  • Boost Operational Efficiency: Streamline workflows, reduce administrative burden, eliminate bottlenecks

  • Improve User Experience: Create an intuitive system that empowers LOTO specialists to focus on safety, not paperwork


Research Process

Discovery: Understanding the Existing Process

Methodology:

  • Desk Research: Reviewed existing Lockout/Tagout Programs and OSHA compliance standards (29 CFR 1910.147) to understand regulatory requirements and company policies

  • User Interviews (N=6): Conducted in-depth interviews with LOTO specialists to gather first-hand insights on current workflows, daily tasks, pain points, and challenges

Key Research Insights:

  • Complexity: LOTO procedure was far more intricate and multi-step than initially perceived

  • Manual Documentation: Paper forms were time-consuming, error-prone, and difficult to track/update

  • "Temporary Lift" Bottlenecks: Frequent temporary lifts required repetitive authorization, documentation, and notification steps, creating significant delays

  • Coordination Challenges: Delays in notifying personnel about LOTO status changes and ensuring clear client communication

  • Compliance Risk: Manual processes increased risk of non-compliance, fines, and safety incidents

Visualizing Complexity: Process Mapping

Methodology: Developed a detailed process map visualizing the LOTO user journey from order placement through invoice approval, explicitly highlighting manual handoffs, repetitive tasks, and communication points.

Insight: The map revealed a highly complex, multi-step workflow with frequent temporary lifts, permit revalidation, and client coordination—pinpointing specific areas ripe for digital optimization. This served as a crucial blueprint for the proposed solution's functionality.

Iteration & Impact

Implementing Research Insights

Based on critical feedback from usability testing, the digital prototype was iteratively refined, significantly improving the Temporary Lift workflow.

Key Improvements:

  • Reduced cognitive load through simplified navigation and terminology

  • Improved efficiency via automation and real-time validation

  • Enhanced clarity with visual cues and contextual help

Measurable Outcomes:

  • User Interviews: 6 conducted to define initial problems

  • Usability Tests: 5 completed in first round (with 3 more planned)

  • Efficiency Gain: 30% increase in permit handling efficiency

  • Cost Savings: Estimated $300K saved annually in fines, administrative costs, and avoided downtime

Blueprinting the Solution: Research-Informed Features

Methodology: Based on identified pain points and workflow complexities, I collaborated closely with stakeholders and the designer to define core features of the digital solution.

Key Design Principles:

  • Mobile-First Design: Essential for on-site LOTO specialists

  • Centralized Notifications: Streamline communication during dynamic events like temporary lifts

  • Offline Functionality: Critical for areas with limited connectivity on large construction sites

Proposed Features:

  • Digital Permits & Forms: Replace paper with easy-to-fill, trackable digital forms with templates

  • Streamlined Temporary Lift Workflow: Automated authorization, digital checklists, instant notifications

  • Real-Time Notifications: Automated alerts for key actions (permit approvals, status changes) via multiple channels

  • Centralized Documentation: Single source of truth for all LOTO-related records, improving searchability and audit readiness

  • Training Modules: Built-in resources to ensure user understanding and compliance tracking

Validation & Testing

Usability Testing with LOTO Specialists

Methodology: Recruited five LOTO specialists for first-round usability testing on a high-fidelity prototype. Observed how users interacted with digital flows, specifically around permit creation, temporary lifts, and navigation.

Uncovering Critical Pain Points

Quantitative Findings:

  • 80% of users struggled with navigation and unclear button functionality

  • 60% found field labels confusing or redundant

  • 100% requested automation features to reduce manual effort

  • 6 distinct pain points identified in the Temporary Lift form (cited as most frustrating workflow)

Qualitative Findings & Recommendations:

1. Confusing Navigation & Workflow

  • Problem: Users struggled to find forms (e.g., temporary lifts, E-Remove) and understand process steps

  • Recommendation: Implement clear, hierarchical menus, breadcrumb trails, progress indicators, and guided workflows for complex actions

  • User Quote: "There's a lot of info on here... I'm not sure what you would name it, but it'd be like a lot of overview of everything 'cause this content engine here is like showing everything." — User #3

2. Unclear Terminology & Field Labels

  • Problem: Jargon, inconsistent terms, and redundant fields caused confusion

  • Recommendation: Use simplified, consistent language, tooltips, examples, and conditional logic to reduce cognitive load

3. Lack of Automation & Data Validation

  • Problem: Users desired less manual effort and more error prevention

  • Recommendation: Implement auto-population, real-time validation, and automated notifications/approvals for key actions

  • User Quote: "If there's a way... instead of dragging and dropping the work authorization sheet, if there was a way to search for the work authorization number and then have that work authorization system automatically upload that sheet just by entering in the number." — User #5
