Digitizing Safety Protocols with Smart LOTO
Dhar Cement Works eliminated its paper-based LOTO program and replaced it with Innvendt's Smart LOTO system—achieving 100% permit compliance and a 75% reduction in permit issuance time within three months of deployment.
The Challenge
“Dhar Cement's internal safety audit revealed three systemic gaps in its LOTO program: 23% of maintenance work orders completed without a corresponding LOTO permit record (suggesting permits were being issued but not filed, or work was proceeding without permits), average permit issuance time of 45 minutes due to serial approval routing across three signatories, and no mechanism to verify that isolation points had been physically checked against the permit before work commenced. A regulatory inspection had noted similar findings and issued a compliance improvement notice.”
The Solution
Innvendt Smart LOTO was deployed to replace the paper permit system. Smart padlocks were installed at 80 critical isolation points (main breakers, valve lockout points, and hazardous energy sources). Digital permits are issued through the Innvendt mobile app with automated approval routing; permit validity is linked to smart padlock status—a permit is only active when all required padlocks are confirmed placed.
Implementation
Smart Padlock Deployment and Mapping
80 smart padlocks were deployed at critical isolation points across the plant, each assigned to a specific isolation point in the LOTO isolation database. Each isolation point was photographed and documented with its isolation procedure (the specific action required to isolate that energy source), enabling future permit recipients to confirm the correct isolation action from the app without requiring supervisor guidance for routine procedures.
Digital Permit Workflow Design
The digital permit workflow was designed with input from the plant's maintenance supervisors, safety team, and operators. Permits are initiated by the maintenance supervisor in the Innvendt app; the app automatically identifies all required isolations based on the equipment being worked on (using the plant's equipment-to-isolation-point mapping database). Approval routing is parallel (all three signatories receive simultaneous approval requests), reducing the sequential approval delay from 45 minutes to under 5 minutes.
Compliance Monitoring and Reporting
The plant safety manager's dashboard shows real-time permit status: active permits, pending approvals, overdue permit closures, and equipment with outstanding permits. Automated daily reports to the safety manager flag any maintenance work orders without a corresponding active LOTO permit—the primary compliance gap identified in the original audit. Monthly compliance reports are automatically generated for the plant director and can be shared with regulators on request.
