Chemical Process Safety (PSM/RMP)

At 8:15 a.m. on February 1, 2022, an employee poured paraformaldehyde into an aqueous ammonia solution inside a vessel. There was a chemical reaction, resulting in an explosion. Two employees suffered chemical burns to their backs and arms, and one of the employees was hospitalized…. Membership Required You must be a member to access this...

  The rupture of the V-1 vessel appears to have caused a boiling liquid expanding vapor explosion (BLEVE, pronounced ‘blev-ē). A BLEVE is the “sudden loss of containment of a pressure-liquefied gas existing above its normal atmospheric boiling point at the moment of its failure, which results in rapidly expanding vapor and flashing liquid. The…...

New York City’s Community Right-to-Know Law (Local Law 92) requires facilities where extremely hazardous substances or regulated toxic substances are present at or above federally determined levels (Threshold Planning Quantity), to prepare and submit a Risk Management Plan to the Department of Environmental Protection on or before March first of every year. In situations where…...

We have recently heard the phrase “inherent safety” used by OSHA and EPA as both agencies work at revising/updating their process safety standards.  But what exactly is “inherent safety,” and why is it at the top of the Hierarchy of Controls for process safety? Inherently safer practices are an approach to designing safer chemical plants,…...

Pay close attention to the break in the smoke plumes on the right hand side of the screen… Today, the U.S. Chemical Safety and Hazard Investigation Board (CSB) released its final investigative report into a massive fire and explosions at the Philadelphia Energy Solutions (PES) Refinery in Philadelphia, Pennsylvania, that occurred in June 2019. The…...

Many organizations have become very good at identifying the ACTIVE failures associated with an accident; however, in almost all of the accident investigations I have been involved with, I find LATENT failures to play a bigger role than active failures.  But that is a really hard pill for most organizations to swallow.  But there is…...

A North Carolina Administrative Law Judge found that railcars on a “siding” are a “stationary source,” as such, if they contain an EHS over the RMP threshold, they fall under EPA’s Risk Management Plan. This is in line with EPA’s recently proposed changes wanting to apply a 48-hour time frame to the term “storage, not…...
