Leading up to this month’s 2012 U.S. Presidential election, the legislative landscape has been relatively uneventful. On top of their preoccupation with the election campaigns, lawmakers on both sides of the political spectrum have been reluctant to pin their agendas to any bill that might significantly alienate large groups of voters. Nevertheless, two relatively significant changes are coming down...

Preventing dust explosions is not rocket science, and still these disasters occur. This article is written to help prevent these accidents. It describes how and why these explosions happen and what can be done to avoid them.   Why they occur Dust explosions occur when three conditions are present simultaneously. The first is that there is a dust cloud of a combustible material (the fuel). The second...

This article is the first in a two-part series, in which the types of process vacuum equipment (steam ejector systems and mechanical vacuum pumps) are discussed.1 Emphasis is given on how they are constructed and operate, and how to design associated parts of the systems (such as foundations, suction piping, discharge piping, and so on), to ensure safe operation. Many unit operations — including...

The U.S. Chemical Safety Board (CSB; www.csb.gov) has released a new safety video that examines the concept of inherent safety and its application across industry; “Inherently Safer: The Future of Risk Reduction” stems from the August 28, 2008, explosion that killed two workers and injured eight others at the Bayer CropScience chemical plant in Institute, W. Va. As a result of ongoing concern...

In designing and sizing relief-device and effluent-handling systems, one commonly overlooked aspect of the performance is examining the potential for low temperatures that can cause the components of the system to reach temperatures below their respective, minimum-design metal temperatures (MDMT), which may result in brittle fracture with subsequent loss of containment. This article points out limitations...

After a serious accident at a chemical plant, petroleum refinery or other freestanding industrial facility, the U.S. Chemical Safety Board (CSB; www.csb.gov) may immediately initiate an investigation, often getting “in the air” while the emergency is still unfolding. The CSB team will consist of skilled accident investigators who are often accompanied by independent experts noted for their...

Circa 1978, Reese and I visited a petrochemical plant in Corpus Christi, Texas. Primarily, our job was to inspect trays that had been installed in three columns. Each of those columns was about 10 ft in diameter and 100 ft tall. Our first mistake: We tried inspecting all three columns on the same day. By the time we got to the third column we were physically drained. Nevertheless, with shaky legs and arms...

An explosion is defined as “a rapid increase in volume and release of energy in an extreme manner,” and is usually accompanied by high temperature generation and gas release. Flammable gases, vapors, dusts and ambient oxygen — all present in chemical processing facilities — can react to cause an explosion that essentially creates a shock wave. As a result of modern production...
