Learn how to identify risks, follow safety procedures, and maintain a safe and compliant work environment.
The 4,000-liter glass-lined reactor on Line 3 doesn’t look dangerous. Stainless jacket, temperature controller, a relief valve piped to the scrubber system. But inside that vessel, an exothermic reaction running 12 °C above its designed operating window can generate enough pressure to rupture the relief header and send a toxic vapor plume across the tank … Read more
The nameplate on a junction box reads II 2G Ex db IIB T4 Gb. Twelve characters. Each one references a specific standard, a specific test, a specific limit on how energy can be released inside that enclosure. To the procurement clerk who ordered it, that string is a part number. To me, standing in a … Read more
The exothermic reactor sat at the centre of everything — three feed streams converging into a jacketed vessel running at 185°C, with a pressure relief system sized for runaway conditions that the original designers hoped would never materialise. The piping and instrumentation diagram showed seventeen safety-critical instruments on that single reactor loop. But a diagram … Read more
TL;DR: I was standing on a high-rise formwork deck in Calgary when the general contractor’s project manager asked me a question I’ve heard dozens of times since: “What exactly does your NCSO® let you do that someone without it can’t?” The answer wasn’t about a piece of paper. It was about the fact that I … Read more
TL;DR I was reviewing gas test records on a petrochemical turnaround in the Gulf when the attendant’s four-gas monitor started alarming at 14% LEL inside a vessel that had been steamed, purged, and signed off as gas-free just forty minutes earlier. The vessel had residual hydrocarbons trapped behind scale buildup on the internal baffles — … Read more
TL;DR I was conducting an air monitoring survey inside a chromium electroplating shop at a metal finishing facility in the Midwestern United States when the plant manager asked a question I’ve heard dozens of times across my career: “Why does it matter that you’re a CIH? Can’t any safety guy take these samples?” I pointed … Read more
TL;DR I was conducting a management system audit at a refinery complex along the Gulf coast when a young safety coordinator pulled me aside during a break. He had three years of field experience, a degree in environmental science, and a stack of training certificates — but every job posting he applied for listed “ASP … Read more
TL;DR I was reviewing incident investigation summaries for a pipeline construction project in Central Asia when a pattern jumped off the page. Eleven recordable injuries over eight months — and nine of them involved workers who had been on rotation for more than 28 consecutive days without a proper rest break. Two of those workers … Read more
Three years into a role managing process safety at a gas fractionation complex, I sat through a corporate leadership review where an executive pointed at the facility’s Total Recordable Injury Rate — it had dropped to 0.24 — and declared the site “the safest in the portfolio.” The operations manager beside me shifted in his … Read more
TL;DR I was standing in a turbine hall during a planned maintenance shutdown at a gas-fired power station in the Gulf when the lead mechanical engineer handed me a three-ring binder. “This is our FMEA,” he said. The binder was two years old. No updates since commissioning. No link to the permit-to-work system. No connection … Read more
