When flammable or combustible atmospheres are present, uncontrolled discharges of static electricity are potentially dangerous or even catastrophic. A significant portion of industrial explosions and fires are attributable to static electricity each year. In theory, controlling static electricity by grounding potential sources is simple, but in practice, doing so effectively requires thorough knowledge of...

Big-time security threats and breaches, like the recent Target data breach involving confidential consumer information, remind us of how vulnerable our interconnectivity makes us. And yet, the advantages of the technological advances that we enjoy are so many that there is no turning back. In his keynote presentation at the recent ARC Industry Forum (February 2014; Orlando, Fla.; www.arc.com), ARC Advisory...

About thirty years ago, my golf foursome learned an important safety lesson and we credited the Dalai Lama. We were all big fans of the movie “Caddyshack.” In that movie, Bill Murray’s character talks about caddying in the Himalayans for the Dalai Lama and states, “So I’m on the first tee with him. I give him the driver. He hauls off and whacks one — big hitter, the Lama...

As an owner or manager of a company whose product is regulated by the U.S. Food and Drug Administration (FDA), you will, at some point, be subjected to an FDA inspection. And once an inspection is underway in your facility, anything affecting the drug or food product directly or indirectly in an adverse manner is within the purview of the FDA inspectors. If discrepancies are found during such an...

Workers in the chemical process industries (CPI) can wear chemical protective clothing to protect themselves from exposure to potentially hazardous chemicals in the form of vapor, liquid and solid particles. While chemical protective clothing has not been regulated to the extent that safety glasses, hard hats and some other forms of personal protective equipment (PPE) have been, an international standard...

Dust is a critical consideration in the chemical process industries (CPI) from both a process safety standpoint — as a potential fire and explosion hazard — and from an occupational safety standpoint — as a potential worker exposure hazard. Reinforcing basic concepts about dust behavior and properties can help reduce the risks. Health hazards Airborne particles are solids suspended in the...

Rising temperatures and rapid or excessive heat buildup are useful markers for determining the operational health of many types of machinery and components that are used in a wide array of industrial and manufacturing settings. The types of mechanical and electrical systems for which temperature increases often signal problems include (but are not limited to): rotating machinery, such as motors, turbines...

It is with extreme reticence that I author this page, even though I received permission several months ago to do so. FRI had a near miss in 2010, which was identical to a near miss that occurred in 2007. In the safety world, such things should never happen. In 2007, FRI was running butanes in its high-pressure test column. A gasket blew, releasing butanes to the atmosphere; the butanes did not ignite...

Working in close proximity to the high pressures and temperatures commonly found in the chemical process industries (CPI) is cause enough for concern over a person’s wellbeing; but working in close proximity to chemicals that are considered toxic, hazardous or reactive escalates that concern to a higher degree (Figures 1 and 2). The dangers of such chemicals underline the paramount importance of...

Newson Gale Avert static electricity buildup with this hose-continuity tester The OhmGuard Hose-Continuity Tester is designed to continuously ensure that a string of assembled hoses are safely grounded to the transferring vehicle during operations that may produce potentially combustible gas, vapor or dust atmospheres. These testers protect against static electricity that can accumulate to dangerous levels...

Security of SCADA (supervisory control and data acquisition) and other industrial control systems (ICSs) is a complex subject, and one that has received much attention in recent years. While modern industrial control systems use many of the same computers, operating systems and networking components as conventional business networks, the two kinds of networks are managed very differently. As a result, what...

During process operations, elevated pressure inside of isolated zones within a process or system can be rapidly reduced by the release of gas and vapor to a dedicated blowdown network. Analysis can be carried out to determine whether a given pressure-relief device will provide sufficient protection from potential vessel rupture for an unwetted-wall vessel or a vessel containing a high-boiling-point liquid...

Ongoing advances in the design and use of dry gas seals (DGSs; [ 1]) — as an alternative to traditional oil-lubricated wet seals [ 2] — have helped to improve the reliability and efficiency of compressors throughout the chemical process industries (CPI). One of the major design considerations in mechanical seals is how to protect seal faces from wear, as one face rotates close to a static face...

Some injuries are permanent; some injuries are total. People who work for, or near, small companies need to be protected just as much as those associated with large companies. Small companies, however, usually cannot afford to employ full-time, certified, degreed, safety professionals. From my own career experiences, it seems as though a company with less than 50 employees cannot afford to employ an expert...

The U.S. Occupational Safety and Health Admin. (OSHA; Washington, D.C.; www.osha.gov) has flagged combustible dusts as one of its top issues since the Imperial Sugar Mill explosion in Port Wentworth, Georgia, that killed 14 employees and injured many others in February 2008. Combustible dust is, in fact, one of OSHA’s National Emphasis Programs (NEPs).   The situation today Despite the...

What if someone were to tell you that there is one method available for sizing relief valves that applies to virtually every situation, including two-phase flow and supercritical fluids? And what if they told you that method is more accurate and easier to use than traditional methods or formulas? As it turns out, both of these statements are true. The approach described here — the Direct Integration...

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...
