Pisys PTW: Your Integrated Safe System of Work
An ISSOW is a unified digital system designed to manage all high-risk work activities. An ISSOW integrates every safety-critical element into a single platform:
- Permit to Work (PTW)
- Risk Assessment (RAMS)
- Isolation Management (LOTO)
The Pisys system also covers
- Contractor Management
- SIMOPS Control
By integrating all these elements into a single system, the Pisys ISSOW ensures that no hazardous work can commence until all prerequisite safety measures have been verified, approved, and recorded in real-time. It is the core of modern, effective Control of Work (CoW).

Safety, Efficiency & Compliance
Why ISSOW?
Before ISSOW, managing operational risk was fragmented and time consuming. Traditional, paper-based, or siloed electronic systems often lead to:
- Procedural Gaps: Work Permits are approved without confirming necessary isolations are in place, leading to dangerous simultaneous operations (SIMOPS).
- Poor Visibility: Management lacks a real-time view of all work activity across all sites, hindering quick decision-making and emergency response.
- Inefficiency & Delays: Paper permits require physical sign-offs, causing significant downtime and delaying critical work.
- Compliance Risk: Inconsistent documentation and difficult auditing make proving compliance challenging and expose your organisation to regulatory penalties.
An Electronic Integrated Safe System of Work (ISSOW) is the necessary evolution, moving safety management from a checklist to a seamlessly integrated ecosystem.
Pisys Provides A Complete ISSOW
Pisys Permit To Work System was engineered from the ground up to function as a complete ISSOW. We provide:
- Virtual Permit Board: Real-time, centralised visibility of all live permits, isolations, and SIMOPS conditions across your entire operation, accessible anywhere via the cloud.
- Offline Mobile Capability: Our mobile app allows your field staff to manage permits, sign on/off, and perform isolations in areas with poor or no internet connectivity. All data syncs automatically when connection is restored.
- Configurability and Compliance: Fully compatible with regulatory guidelines like HSE's HSG250, seamlessly adaptable to your specific existing Control of Work system and supports compliance with HSE/ISO/OHSAS standards.
- Rapid Implementation: We build digital versions of your existing permits and risk assessments, allowing your team to transition quickly and minimise downtime. We also train you to configure the system to suit your own business needs
The Only System You Need
Pisys Permit To Work System improves safety and efficiency across the entire workflow.
Safety & Risk Reduction
Eliminates human error by enforcing procedural steps (e.g., permits must reference a current isolation). Reduces SIMOPS risk with centralised visibility.
Operational Efficiency
Drastically cuts permit processing time, leading to faster job start-up. Less paper, fewer delays, more productivity
Audit & Compliance
Creates a complete, tamper-proof audit trail for every action, sign-off, and isolation, making regulatory audits seamless and stress-free
Data & Visibility
Provides powerful data analytics on work trends, risk hotspots, and compliance gaps that are impossible to obtain from paper records.
What Our Customers Say
Quick To Implement
We selected the Pisys system because it was extremely quick to implement, it matched our requirements very well, and was very easy to configure. Pisys staff helped us at every stage and provided on-site training to our team. We were delighted with their commitment, and they have continued to be a great partner for us as we extend our use of the system.
Better Service to Clients
This was a really great strategic move for us. We're now able to work more efficiently and plan tasks more effectively, which in turn means our clients get a quicker response.
Extremely Simple And Effective System
Having adopted the Pisys Permit to work system we now have great visibility on all engineering activities, and we have an extremely simple and effective system to issue and manage permits. Pisys were easy to work with, they understood the issues we faced and were extremely responsive to our questions.

Frequently Asked Questions
ISSOW (Integrated Safe System of Work) is a structured electronic system combining PTW, risk assessment, isolations, and task planning into one safety framework.
ISSOW ensures hazardous work is performed safely by identifying risks, enforcing controls, standardising processes, and maintaining audit trails.
PTW is one component within ISSOW. ISSOW integrates Permit To Work with risk assessments, isolations, SIMOPS, workflows, and approvals.
CoW is the overall safety management framework which includes processes, systems and culture. ISSOW is one tool used to implement CoW.
Typically ISSOW is used by Permit issuers, performing authorities, isolating authorities, HSE advisors, supervisors, and operations/maintenance teams.
ISSOW is used for high-risk work such as hot work, confined space entry, electrical work, working at height, lifting operations, hazardous substances, and isolations.
Although workflows can be slightly different the norm is : Define task → identify hazards → risk assessment → plan isolations → check SIMOPS → approve → issue permit → execute → monitor → close out and reinstate.
Key benefits of ISSOW are: Reduced paperwork, improved safety, better coordination, fewer errors, real-time visibility, stronger governance, clear accountability.
Change always brings challenges - Typically an ISSOW implementation will bring challenges in training, process change, system configuration, resistance to change, ensuring consistency, and maintaining data quality.
ISSOW supplements training but doesn’t replace competency requirements, toolbox talks, or inductions.
ISSOW helps with SIMOPS by highlighting overlapping tasks, flagging conflicts, coordinating approvals, and providing a single view of concurrent work.
ISSOW risk assessments will include: Task steps, hazards, consequences, existing controls, required controls, and residual risk.
ISSOW provides isolation certificates, LOTO processes, design/reinstatement workflows, and verifications.
Some ISSOW systems work offline; others require connectivity. Offline capability is common for remote/offshore use. The Pisys ISSOW allows syncing of permit data with our mobile app so work can be carried out in areas with limited or no connectivity.
Since ISSOW is supporting safety critical tasks it is important that it provides a full record of all changes made with job history, signatures, timestamps, change logs, and full traceability.
Pisys ISSOW can be customised — permit types, templates, hazard prompts, risk matrices, workflows, and isolation processes can be tailored.
ISSOW is used in practically every industry but it's very common in Oil & gas, petrochemical, power generation, renewables, mining, marine, food and drink and heavy industry.
ISSOW can integrate with CMMS systems (such as SAP/Maximo), training/competency databases, isolation systems, and handover tools.
Cyber Essentials Plus Certified
Cyber Essentials Plus helps us guard our organisation against cyber attacks. This is important because vulnerability to basic attacks can mark us out as a target for more in-depth unwanted attention from cyber criminals and others. Certification gives us and our customers peace of mind that our defences will protect against the vast majority of common cyber attacks simply because these attacks are exploiting targets which do not have the Cyber Essentials Plus technical controls in place.
ISO 27001 Certified
We strive to ensure the integrity, confidentiality and availability of all systems and data used by Pisys in their delivery of hosted applications to their worldwide client base, protecting these systems and data from all threats, internal and external, deliberate and accidental. To do this, we have deployed an information security management system (‘ISMS’) compliant with the ISO/IEC 27001 information security standard to meet our information security policy. The ISMS will allow compliance with customer contracts, and relevant laws of the UK and any company within which Pisys Ltd operates.
