Pipeline Safety & Potential Impact Radius (PIR) Re-evaluations

/ Chemical Process Safety (PSM/RMP), Free, Hazardous Materials /

NTSB’s historical investigations into major gas and hazardous liquid pipeline ruptures continue to shape current rulemaking tracking. PHMSA has been actively reviewing the established Potential Impact Radius (PIR) calculation methodologies used in integrity management programs. The review aims to determine whether current mathematical models accurately account for human response data, rapid-ignition variables, and modern accident […]

FRC must be the outer layer – NYLON Hi-Vis vest are a problem

/ Chemical Process Safety (PSM/RMP), Emergency Response, Free, Hazardous Materials, OSHA Compliance /

In today’s workplaces, it’s hard to find a large business that does not require Hi-Vis Vest/Workwear. What is not hard to find is a business with HAZLOCs where workers are required to wear FRC but are wearing nylon Hi-Vis vests OVER their FRC. I am all for making workers more visible to powered industrial trucks

When you see it… Flange Jumpers for Flammable Liquid & Combustible Dusts Piping

/ Chemical Process Safety (PSM/RMP), Flammable Liquids, Free, Hazardous Materials, OSHA Compliance /

Many may be familiar with “flange jumpers,” or some may call them “bonding jumpers,” that are used to ensure a continuity to ground across a flange with gaskets that act as “insulators”, such as PTFE gaskets. During a recent walkdown of a flammable liquids process, I came across this “jumper”. Design called for “jumpers” on

Gemini+ analysis of my Double Block and Bleed Isolation and Line & Equipment Opening ppt

/ Chemical Process Safety (PSM/RMP), Free, Hazardous Materials, Lockout Tagout, OSHA Compliance, Process Safety Material /

Establishing a Double Block and Bleed (DB&B) positive isolation is a critical safety protocol when preparing piping and equipment for opening, especially when dealing with Extremely Hazardous Substances (EHS). This process ensures that hazardous materials (HAZMAT) are effectively evacuated and isolated to protect workers from accidental releases. Members can download my .ppt file at bottom
