Problem
Traditional lockout-tagout (LOTO) and permit-to-work systems rely on physical boxes, locks, hasps, tags, and paper-based forms, which are cumbersome to manage and prone to errors. Manual data entry and disconnected approval workflows slow down job execution, create tracking gaps, and increase the risk of safety incidents during maintenance and high-risk operations.
Solution
Deltafour offers an end-to-end digital safety management platform that replaces physical LOTO boxes and paper permits with a unified software solution. The platform digitizes both LOTO and permit-to-work processes, enabling automatic permit generation, streamlined multi-step approvals, and real-time status tracking. It includes a digital HIRA and JSA module that helps teams identify hazards and assess risks before starting any task. The system is designed for seamless integration into existing operational systems, reducing manual data entry and improving efficiency across industrial workflows.
Target Audience
Deltafour serves industrial organizations including manufacturing plants, processing facilities, and maintenance operations that require formal permit-to-work and lockout-tagout compliance. Primary users include safety managers, maintenance supervisors, and frontline workers performing high-risk tasks across mechanical, electrical, and operational departments.
