Updating on the dimensional criteria for the design of ‘Ex d’, ‘Ex de’ enclosures for Panel Boards: the new standard of cable entry

08/21/2018

The Standards which regulate the installation criteria of electrical products and equipment for use in hazardous areas have been constantly updating. Particularly, it has been recently amended the standard of cable entry/exit from 'Ex d' junction boxes, whether for IIB or IIB + H2 or IIC group. For this reason, we face in this study the changes introduced by updating the technical article of May 2014.

08/14/2018

Explosions and fires at oil refineries and chemical facilities are far more likely to occur during equipment start-ups and shutdowns, notes the U.S. Chemical Safety and Hazard Investigation Board (CSB) in a recent Safety Digest. Workers are typically the first line of victims when such incidents occur. In the Digest, the CSB describes three start-up/shutdown incidents it investigated in which collectively 5 workers were killed and 11 injured.

Process plant owners/operators have an obligation to assess and ascribe the residual risk of an unmitigated explosion occurrence under the ATEX Directives, and in doing so are making a key decision on the acceptability of that residual risk. All safety systems have a residual risk that they fail to achieve their mission, whether it be via hardware failures, personnel errors, errors in the theoretical and design assumptions, or inadequacies in the quantification of the prevailing hazard.

Fires in Industrial and Manufacturing Properties - part 1

06/11/2018

During 2011-2015, there were an estimated 37,910 fires at industrial or manufacturing properties (including utility, defense, agriculture, and mining) reported to U.S. fire departments each year, with associated annual losses of 16 civilian deaths, 273 civilian injuries, and $1.2 billion in direct property damage. The vast majority of these fires (71%) occurred in outside or unclassified locations, with another 20% taking place in structures and 9% of the fires in vehicles. The 20% of fires taking place in structures accounted for the largest shares of losses in all categories – 49% of civilian deaths, 80% of civilian injuries, and 67% of direct property damage. Almost two-thirds (65%) of the combined industrial or manufacturing facility structure fires occurred specifically in manufacturing properties (as opposed to utility, industrial, defense, agriculture, and mining properties).

RIGID IBC Venting In some applications, IBC may be designed to withstand the maximum explosion pressure generated by a dust explosion. These vessels would be designated as pressure resistant vessels or pressure shock resistant vessels, but the cost is high and IBC of this strength are not common. Most rigid IBC are classed as weak vessels with, typically, a metal wall thickness of 2–3 mm with a maximum strength in the order of 0.3–0.4 bar.

Summary Explosions never happen at random, they have their exact laws. And sometimes they need very little – high dust concentration, turbulence and ignition source, often spontaneous combustion. If these conditions are met, explosions always follow. It needs to be mentioned that all organic substances are explosive, for example starch, flour, dried milk, sugar, cocoa, pharmaceuticals, textiles, wood and coal dust and others.

Floating Roof Tank Fires are Common - There are some 15 to 20 known Floating Roof Tank (FRT) fires per year. Floating Roof Tanks are especially vulnerable to the direct and indirect effects of lightning. A direct or a nearby lightning strike can cause electrical current to flow across the tank shell and roof. When these lightning currents arc across the roof/shell interface, they can ignite any flammable vapours present with devastating effect.

10/10/2017

Handpoured tea leaves go through several processing steps before we can enjoy a delicious cup of freshly made tea. One of the steps is drying the tea leaves. This is done using hot air flow. However, the tea leaves generate fine dust particles which, when airborne, may cause dust explosion hazards. To prevent this from happening, Ex-Machinery developed a special ATEX heater that dries the leaves safely with an ingenious airflow – without the risk of burning the tea leaves.

Wiring Requirements in Hazardous Locations

09/26/2017

One common way of minimizing possibilities of electrical wiring and equipment becoming an ignition source in hazardous (classified) locations is to locate the equipment and wiring outside of the hazardous (classified) location wherever possible. This is always a practical approach and a good exercise of ingenuity, although it is not always possible. Often equipment and wiring installations have to be located within hazardous (classified) locations, and safe installations require a thorough understanding of more restrictive wiring rules.
