A FREE TOOL/Resource every safety pro should have in their toolbox – CGA Handbook of Compressed Gases

Did you know? The Compressed Gas Association’s Handbook of Compressed Gases is now available online — completely FREE and publicly accessible. Access it here:  https://handbook.cganet.com For decades, the Handbook has served as a trusted reference for professionals across the industrial, medical, food, beverage, specialty gas, and hydrogen sectors.  Now, CGA has transformed this essential resource into […]

Line Break gone bad (H2S – pulling blind)

Shenyang Petrochemical Company “The Big Poisoning Accident“ The gas sub-device of Shenyang Paraffin Chemical Company suffered a poisoning accident during the maintenance and construction process, resulting in three (3) Deaths. The immediate causes of the accident were: When the operator carried out the blind plate swapping operation at the pump relief blind plate, the operator

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

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

Why we want to ALWAYS Hydrostatically Test our chemical hoses vs. Pneumatically Testing

As I have written many times, our bulk chemical transfer hoses MUST be part of an Inspection and Testing Program. These tests follow the same logic as pressure testing piping, and Hydrostatic Testing is far safer than pneumatic testing. So I asked Google Gemini+ to show me the difference in failure energies to demonstrate this

Pressure Wave generated by a 1-ton Cl2 cylinder catastrophically failing (WCS for Cl2 1-ton cylinder inside a Cl2 building)

So I asked Google Gemni + to calculate the pressure wave in a room that is 40′ X 40′ X 20′ tall with the catastrophic failure of a 1-ton chlorine cylinder. In a 32,000 ft3 room, we must determine the volume of gas released during the “instantaneous flash” and the resulting internal static overpressure.

I have created a “cheat sheet” for safe distances during pneumatic pressure testing (ASME PCC-2, Mandatory Appendix 501-III)

DISCLAIMER: This is a “cheat sheet” for safety professionals to get a general idea of the “safe distances.” ALWAYS refer to ASME PCC-2, Mandatory Appendix 501-III) for the exact distance. Just understand, ALL pneumatic pressure testing REQUIRES a “safe distance”. According to ASME PCC-2, Mandatory Appendix 501-III, determining safe distances for pressure testing—specifically, pneumatic testing—requires
