If there’s one part of Process Safety Management (PSM) you can’t afford to get wrong, it’s your Process Hazard Analysis (PHA). A PHA is designed to identify potential hazards in your system before they become incidents. But too often, facilities treat it like a checklist instead of a critical evaluation. A proper PHA should examine: System design Operating conditions Failure scenarios Human factors Maintenance procedures This isn’t something that should be templated or rushed. At Doubl-Kold, we approach PHA with real-world expertise. Our team understands how refrigeration systems operate—not just how they look on paper. That means we identify risks others might miss—and avoid recommending unnecessary changes that drive up costs. PHAs must also be updated every five years, making them closely tied to your Mechanical Integrity (MI) program. If your PHA is outdated, incomplete, or generic, it can put your entire PSM program at risk. We also ensure PHAs align with: RMP requirements General Duty Clause expectations Actual facility operations The goal isn’t just compliance—it’s protection. If your PHA hasn’t been reviewed recently, now is the time. Give Doubl-Kold a call and let’s make sure your system is evaluated the right way.

One of the most common questions we hear is: “Do I need PSM if I’m under 10,000 pounds of ammonia?” The short answer? Not fully—but you’re far from exempt. While OSHA’s full Process Safety Management (PSM) requirements apply at 10,000 pounds, facilities below that threshold are still required to follow the General Duty Clause. This means you must: Identify hazards Maintain safe operating procedures Ensure proper equipment maintenance Prevent known risks In practice, many facilities still need to implement 70–80% of a PSM program, even if they are technically below the threshold. This includes maintaining: Updated PNIDs Basic Mechanical Integrity programs Standard operating procedures (SLP/MIP) Training documentation Ignoring these elements can lead to serious consequences—not just fines, but operational failures. At Doubl-Kold, we work with facilities on both sides of the threshold. We tailor compliance strategies so you’re not overbuilding—but also not leaving yourself exposed. This is where our experience matters. With over 80 years of combined expertise, we know what regulators expect—and what your system actually needs. We often help facilities avoid unnecessary compliance costs while still meeting expectations—something that larger firms don’t always prioritize. If you’re unsure where your facility stands, don’t guess. Give us a call and we’ll walk you through exactly what applies to you—and what doesn’t.

Ammonia refrigeration remains one of the most efficient and widely used solutions in industrial cooling. But with that efficiency comes responsibility—specifically, compliance with Process Safety Management (PSM) and Risk Management Program (RMP) requirements. In 2026, regulatory enforcement is increasing, and facilities using ammonia systems are under more scrutiny than ever. PSM compliance starts with understanding your system. This includes having accurate Piping and Instrumentation Diagrams (PNIDs), well-documented operating procedures, and a complete understanding of system risks through Process Hazard Analysis (PHA). Many facilities underestimate the importance of Mechanical Integrity (MI). This includes corrosion inspection, equipment testing, and the required 5-year MI review, which is one of the most commonly missed compliance elements. Even facilities under the 10,000-pound ammonia threshold are not exempt from responsibility. The General Duty Clause still applies, meaning you are expected to identify hazards and take action to prevent incidents. Doubl-Kold stands apart because we don’t just understand PSM—we understand refrigeration systems at a deep level. Our team includes licensed engineers and experienced technicians who work directly with ammonia systems every day. That means our recommendations are practical, efficient, and grounded in reality—not generic compliance templates. We also assist with Tier II reporting, RMP updates, and full compliance planning to ensure your facility is prepared for inspections and long-term operation. Most importantly, we help you do it efficiently. Our experience allows us to streamline compliance efforts, often helping clients reduce unnecessary costs while improving safety. If your ammonia system hasn’t been reviewed recently, now is the time. Give Doubl-Kold a call and let’s make sure your system is compliant, efficient, and built for the future.

If you’re searching for PSM assistance, you’re likely facing one of two situations: you’re preparing for an audit, or you’re realizing your current Process Safety Management (PSM) program isn’t where it needs to be. In 2026, that’s a risk you can’t afford to ignore. PSM, as defined by OSHA, is designed to prevent catastrophic releases of hazardous chemicals like anhydrous ammonia, which is widely used in industrial refrigeration. But the challenge isn’t understanding that PSM exists—it’s knowing how to implement it correctly. Many facilities assume PSM is just paperwork. In reality, it’s a system that touches every part of your operation—from Process Hazard Analysis (PHA) to Mechanical Integrity (MI) to standard operating procedures (SLP/MIP) and PNID documentation. Facilities over 10,000 pounds of ammonia are required to follow OSHA’s full 14-element PSM program. However, what many businesses don’t realize is that even those below 10,000 pounds still fall under the General Duty Clause, meaning they must still manage risk appropriately. That’s where experienced support matters. At Doubl-Kold, our team brings 80+ years of combined experience in industrial refrigeration and compliance—not just theory, but real-world application. We help facilities with: PHA facilitation Mechanical Integrity programs 5-year MI inspections PNID development and updates SOP/SLP/MIP documentation RMP coordination Unlike large compliance firms, we don’t take a one-size-fits-all approach. We evaluate your system and build a program that actually fits your operation. And because we understand both engineering and compliance, we often identify areas where facilities are overspending—helping clients potentially save thousands over competitors who push unnecessary upgrades or services. PSM isn’t getting easier. Regulations are tightening, and inspections are increasing. If you’re searching for real PSM assistance that makes sense for your facility, give us a call. Let’s get your system where it needs to be.
