Smarter SOPs for Ammonia Systems

In ammonia refrigeration, documentation is not just paperwork. It is how operators understand the system, improve efficiency, maintain consistent performance, reduce miscommunication, and comply with industry regulations. That is why SOPs and P&IDs need to be accurate, current, and actively used within your PSM program or General Duty facility.

These documents shouldn't just sit in a binder or folder for audits. They should guide training, daily operation, maintenance activities, troubleshooting, emergency planning, and management of change. When the drawings and procedures match the actual system, employees have a clearer understanding of how the process is designed, how it should be operated, and what hazards need to be controlled.

For covered processes, OSHA's PSM standard requires written operating procedures that provide clear instructions for safely conducting covered process activities. P&IDs are the document that complements the written operating procedures and are part of the process safety information for equipment in the process. In other words, the drawing and the procedure are not separate pieces of the program. They should work together.

The challenge is that many facilities have drawings, manuals, and procedures that do not fully connect. A P&ID may show the valves, vessels, pumps, controls, relief devices, and instrumentation, but it does not automatically explain what an operator should do during startup, shutdown, pump-out, oil draining, defrost, emergency response, or troubleshooting. A standard may tell you what compliant looks like, but it does not write the exact SOP that fits your system, your equipment, your valve arrangement, and your operating hazards.

That is where facilities now have the ability to create smarter SOPs for ammonia systems with valuable resources like iPSM. By scanning drawings and supporting documents, iPSM can help draft SOPs using the actual information available within the facility’s program. The key word here "help". One issue we frequently come across is the belief that AI software can be a miracle worker. In reality, the software is only as capable as the information it is given. If your documentation is outdated, those deficiencies need to be addressed before trying to update something deeper in the process. This is where the weak links in your program start to show. When detailed supporting documents are missing, it becomes much harder to improve and support the program.

Traditionally, SOPs are created manually in-house by PSM personnel or completed by consulting teams like MySafety. That approach can still work, but when your team has been asking for months, or even years, to get a procedure updated, the process may have already changed by the time the document is revised. Over time, employees can start losing confidence in their ability to participate and make meaningful improvements within the program. This gap becomes even more serious when a facility needs an SOP created within hours or days for a large, complex project. Without a faster and more structured way to draft and review supporting documents, proper procedures may never get created, and process safety can be put at risk.

Instead of starting with a blank page or a generic template, iPSM can begin connecting the equipment shown on the drawing to the operating steps, limits, hazards, and safety systems that should be considered in the procedure. That does not replace qualified review. It gives your team a stronger starting point. At MySafety, one of the most exciting parts of iPSM is that the software is being shaped by real ammonia refrigeration field experience. The goal is not to build a generic AI writing tool. The goal is to support PSM programs with practical knowledge from people who understand how these systems are operated, maintained, and inspected in the real world. iPSM drafts SOPs the way an experienced ammonia operator would think through the task. It looks for the judgment that often fills the gaps between the industry standard, the P&ID, the equipment manual, and the actual work being performed.

The standards tell you what compliant looks like. They do not always tell you how to write an SOP that is safe, usable, and specific to your facility. iPSM helps draft from that experience, then hands it back to your team to review, verify, and finish. That review step matters. A safe SOP still needs to be checked against the current field installation, current operating practice, management of change history, manufacturer requirements, and the knowledge of the people who actually run the system. AI can help organize, draft, identify gaps, and speed up the process, but the final procedure still needs facility verification.

Every document, drawing, review comment, and contribution can help the system get better. Knowledge compounds. When field experience is captured instead of lost, the next draft starts from a stronger place. Over time, that can help facilities move away from generic binders and toward documentation that better reflects how their systems actually operate. For MySafety, this is why the partnership with iPSM makes sense. Our work has always focused on making compliance practical. A procedure that checks a box but does not help the operator in the field is not enough. A P&ID that lives in a folder but is not connected to training, SOPs, mechanical integrity, and emergency planning is not enough either.

AI is not here to replace ammonia knowledge. It is here to help capture it, organize it, and make it easier to use.
