Safety-Instrumented Systems: Focus on Measurement Diagnostics
This article provides guidance to the designer and operator of a safety-instrumented system (SIS), with an emphasis on conducting measurements. The use of best practices to ensure the strength of the overall system design, and the use of instrument diversity to combat common causes of failure, are covered briefly. Greater detail are provided on the use of new technologies — in particular, new...

Are you ready for inspection?
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...

Vacuum Systems: Recommendations For Safe Operation
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...

Working with the CSB After a Major Accident
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...

Does safety milestone at BP Texas City refinery signify a turnaround?
In 2005, an explosion at the BP Texas City refinery facility killed 15 and injured an additional 180. At the time, it was considered to be the worst industrial accident in 16 years, and continues to top the list. While the incident was expected to serve as a wakeup call for the facility management, workplace deaths continued for at least three years following the 2005 event. And, as late as October 30...

Get the Most out of Vibration Analysis
With productivity, growth and reliability as constant drivers, the proactive evaluation of all machinery is critically important. In order to gain useful insight, the maintenance team must capture comprehensive data related to machinery operation and carry out a logical interpretation of the data. The conventional language of equipment components — vibration — transmits relevant information...

Compressed Gases: Managing Cylinders Safely
Compressed gas cylinders are widely used in research, pilot plant, laboratory and small-scale manufacturing and processing operations as a way to provide a convenient, economical and safe source of high-pressure gases for various applications. These gases can be inert, flammable, toxic or oxidizing (or mixtures of any or all), and are typically supplied at pressures from 800 to 6,000 psig, with 2,250 psig...

Comments on Pressure Relief System Design
I would like to draw your attention to a few points on the November 2008 article, Pressure Relief System Design (pp. 40–45): 1. Pressure drop and pressure loss: The inlet pressure “drop” that the author refers to under Relief system piping is non-recoverable pressure loss, and does not include a “drop” in pressure due to elevation increase. It should be labeled as a pressure...

Pressure-Relief System Design
  Pressure relief systems are vital in the chemical process industries (CPI) for handling a wide variety of situations. They are used to prevent pressurization above a system’s design pressure; for venting during an unusual or emergency situation; and for normal depressurization during a shutdown, as examples. In some cases, such as when non-combustible gases including steam, air and nitrogen...

Environmental Manager: A Checklist for Safer Chemical Batch Reactions
A good understanding of the reaction chemistry is needed for a safe process design It is a fact that safety-related incidents do occur in the chemical process industries (CPI). These incidents have, in part, led to increased attention to reactive-chemical issues by industry, government and other stakeholders. We know that good safety-management systems take the reactivity of chemicals as well as the...

Managing Material Safety Data Sheets in the Workplace
To ensure the health and safety of workers, the U.S. Occupational Safety and Health Administration (OSHA) adopted the Hazard Communication Standard (HCS) in 1983. Initially designed to protect workers in the manufacturing sector, the HCS was expanded in 1987 to cover all industries where workers could be exposed to hazardous chemicals. This article gives an overview of the OSHA requirements for material...

Designing for A Safe Process
    Accidents do happen. While not everything can be predicted, addressing safety concerns throughout the design of a process can help to prevent accidents from occurring. Designing with safety in mind can also help to minimize potentially serious consequences that would result if an accident did occur. On April 12, 2004, toxic allyl alcohol and allyl chloride were released from a reactor at a...
