Here we sit in the year 2018 and here I sit posting about the use of “low-melting-point materials” for use in flammable liquids and flammable gases piping systems – oh the insanity, but this debate seems to happen far too often these days! I have been working with Hazardous Materials, most notably Flammable Liquids and Gases (FLAGs) since 1992 and from my very first fire science class and hazardous materials classes at Murray State University I was taught you NEVER EVER use “low-melting-point materials” for the conveyance of a flammable HAZMAT. And for those of you who are still fighting this fight, either in the PSM arena or just in ordinary uses, we have basic fire codes (even lower in the layers of code than OSHA) that have prohibited this design for decades. The IFC, Chapter 57 FLAMMABLE AND COMBUSTIBLE LIQUIDS states the following: (emphasis by me)
