Fitting Addition To Boost Safety

Flexicon has extended its range of hazardous area conduit systems with the launch of an Increased Safety EX e and Dust Ignition Proof EX t fitting for use with liquid tight conduits.

Ian Gibson, technical director for Flexicon, says: “While our EXD barrier glands can also be used for Increased Safety and Dust Ignition Proof, we recognised that not all hazardous area applications need a flameproof barrier gland and for these we can now provide a system (Read More) 

E2S publishes an information guide to measuring sound levels in dB

E2S Warning Signals, one of the world’s leading independent manufacturers of high-performance audible and visual signals for commercial, industrial, marine, onshore and offshore hazardous locations, has published an educational guide that seeks to ‘de-mystify’ the dB (decibel), one of the most common units in engineering, yet also one of the most confusing. The guide can be found at www.e2s.com/soundbasics. (Read More)

The main difficulty in comprehending dB measurements is that it is a log-linear scale, which, while it is very useful in representing very large differences in a more user-friendly scale, also compresses the scale. Sound is defined as any pressure variation that can be heard by the human ear. The Threshold of Hearing is defined as 0 dB; the threshold of pain is around 130 dB, a scale that can be readily understood. However, as the power difference between the two levels is 1013 : 1, or, to spell it out in full, 10,000,000,000,000 or ten million million to one, expressing it in these terms suddenly gives a much better idea of the change.

The guide sets sounder output levels in context with some everyday examples. For example, the A151 disaster warning sounder is rated at 150 dB, the same as a jet engine at 1m. It also discusses the effect of frequency on perceived loudness and includes some rules of thumb for system designers who are specifying the output and location of warning sounders to provide the desired sound levels as part of a warning system.

ExVeritas can offer testing and assessment to UL and/or CSA listed standards for North American Hazardous Location approval under our unique agreement with TRaC Global and MET.

Hazloc Testing & Assessment

For North American listing (certification) testing is carried out against the relevant UL and/or CSA listed standard for your product type. This type of testing can only be conducted by an approved test body (NRTL or SCC approval laboratory). ExVeritas is an audited and approved third party test laboratory with MET Lab which entitles ExVeritas to conduct testing in the UK for MET certification under the NRTL and SCC schemes and our agreements with TRaC Global as a Certification Body.

Products requiring Hazardous Area listing in North America are also required to meet general industrial safety standards such as UL61010. This is not self-certification as it is in Europe under CE Marking and can require a significant amount of test and assessment.

NEW IEC/EN60079-14:2014 introduces significant new changes for Ex Installers and Inspectors
EN60079-14:2014 Updates

After a great deal of debate, the new Hazardous Area Installation Standard EN60079-14:2014 has been issued and is published as an IEC and EN Standard. As a BS EN Standard there is a rather unusual section essentially saying that although the Standard is published, the UK takes issue with certain parts/changes!

•     Explosion Protection Levels (categories and EPL) updatesEN60079-14:2014
•     New Protection Concepts updates
•     New Ex Installation requirements covering for cable, glands and all protection concepts
•     New Installation tests (restricted breathing on cables etc.)
•     Different Ex d Barrier Gland requirements
•     New Information on RF devices
•     New Intrinsic Safety Requirements

Chesil Beach is located in Dorset, South Coast of England. The shingle beach is approximately 14 miles long and it is part of the Jurassic Coast World Heritage Site. The Chiswell settlement and the southern neck of Chesil Beach have been flooded many times and this is well documented. Many sea defence systems and flood drainages have been constructed at the Portland end of the Chesil Beach to try to alleviate the overtopping and flooding problems.

LOOKING BACK ON A PROUD DAY FOR FIBREGRID

Prince George’s first birthday has been in the news lately. Seems hard to believe that the Duke and The Duchess of Cambridge have been married three years.

It’s fitting to look back at one of FibreGrid’s proudest moments, as our SlipGrip anti slip stair Tread Covers were used on the majority of press and media platforms around London for the Royal Wedding. (Read More)

REDUCE OPERATING COSTS FOR PUMPS & ASSOCIATED PROCESS EQUIPMENT

The performance and reliability of ‘O’ ring sealing systems within process plants can prove to be critical when examining overall plant costs.

This becomes evident where the process fluids are aggressive, or otherwise dangerous to personnel safety, and environmental concerns become involved in the event of process fluid leakage due to seal failures. (Read More)
