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...

Airborne respiratory hazards are a very real threat in the chemical process industries (CPI). Existing in a variety of forms including gases, vapors, dusts, mists, fumes, smoke, sprays and fog, such hazards can cause illnesses including cancer and lung impairment, or even death. Examples of respiratory hazards include combustion byproducts; toxic fumes or dust created by metal melting; ozone and nitrogen...
