Security at many U.S. chemical facilities is currently regulated by the U.S. Department of Homeland Security (DHS; Washington, D.C.; www.dhs.gov) under the Chemical Facility Anti-Terrorism Standard (CFATS). This rule, however, is about to expire this month, October 2009. All expectations are that CFATS will be extended for a year, while proposed modifications to the standard continue to be debated in the...

By definition, integrated safety instrumented systems (SIS) have the potential to reduce risks. But recent advancement is also enabling the use of more sophisticated instruments and tools that can benefit the process. For these reasons, integrated control and safety systems (ICSS) are receiving recognition across the chemical process industries (CPI). “There have been developments from a technology...

The Department of Homeland Security established the Chemical Facility Anti-Terrorism Standards (CFATS) to impose mandatory security regulations on high-risk chemical facilities. Interpreting and fulfilling the regulations present challenges to security directors, but finding the right guidance and working with a security integrator who has experience in the chemical industry can help achieve compliance...

By continuously monitoring for abnormal situations, such as a fire, and combustible or toxic gas releases, fire and gas (F&G) detection and mitigation systems are the linchpins to maintaining overall safety and operation of industrial facilities. The premise of these systems is to protect processes and the environment by providing early warning of incidents and enabling actions that prevent them from...

Protecting process systems from overpressurization is vital throughout the chemical process industries (CPI). Both safety relief valves and rupture disks are commonly used for this purpose. Sometimes the combination of a relief valve with a rupture disk can add service life to the relief valve and prevent process leakage, which is important from safety, conservation and financial standpoints. This article...

Rupture disc devices provide overpressure protection for a variety of storage and process vessels and equipment. The objective of the rupture disc is to maintain a leak-tight seal and be a passive bystander until called upon to relieve excess pressure. While this is generally the case, there are times when rupture disc performance can be adversely affected through various installation, operation and...

Eye injuries of all types occur at a rate of more than 2,000 per day in the U.S., and half of those occur in the workplace. In 2006, the U.S. Bureau of Labor Statistics (BLS) reported over 52,000 workplace injuries to the eyes and face, and approximately 70% of those were eye injuries [1]. The need to protect the face and eyes in the workplace is clear. FIGURE 1.  Safety glasses help shield eyes from...

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 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...

Since the original invention of the steady-stream eyewash over 50 years ago, the accepted practice in the chemical process industries (CPI) and other industrial circles has been to flush the eyes with two, separate, arc-shaped water streams, each one flowing from the outside corner of the eye inward (diagram). A little-known, but potentially serious problem with this approach, says Michael Markovsky, vice...

This article presents the fundamental concepts of the discharge coefficient, KD, of a relief valve or a safety relief valve, and flow resistance factor, KR, of a rupture disk, and their proper use in sizing an emergency relief system. When these devices are used to protect a pressure vessel, they must be certified according to ASME code in the U.S. Both the discharge coefficient and the flow resistance...

Workers in the chemical process industries (CPI) would certainly benefit from the "perfect" glove that would be thick enough for thermal insulation, thin enough to promote dexterity and tough enough to protect workers from cuts and abrasion. The glove would also protect against all known chemicals and be offered at a minimal price. This perfect glove, however, does not exist. Processors and...
