This document provides an overview of electronic permit to work (PTW) systems and integrated safe systems of work (ISSoW) and how they can enable safer safety management. It discusses Engica's Q4 ISSoW software system, which combines elements like risk assessments, isolations, and permits into a unified electronic process. The document also covers practical considerations for implementation like ease of use, speed, and approaches across different industrial sectors. It presents new concepts from Engica like using Microsoft Visio for visual planning of shutdown isolations and a digital dashboard for tracking permit activities.
