xviii UK Focus - Gas Detection Wireless Gas Detection with the BM25 Area Monitor
BM25 Wireless is a tough looking transportable multi-gas area monitor designed for worker protection to ensure safe levels of gas before workers enter hazardous areas, monitoring continuously during welding and other maintenance work , and mobile or short term work in areas where fi xed detection systems are not suitable. Applications include shutdown sites, rig overhauls and fence-line surveillance.
The Wireless BM25 utilises a mesh style network ensuring increased reliability in safety-critical situations. In a mesh network all units are connected peer to peer without central hierarchy, thereby forming a net-like structure. Consequently, each unit can receive, send and relay data.
One of the main benefi ts of the mesh style network over ‘daisy-chain’ non-wireless systems is that should one monitor fail, its neighbours go through another route. Once the fault has been corrected, the communication resumes automatically. The two groups merge together to form only one group again.
Up to 30 BM 25s can be ‘meshed’ on the same network of up to 1Km apart and up to 16 networks can coexist with no interference. Adding a BM 25 on an existing network has never been so easy as you just need to turn it on. The BM25 is automatically added on the network.
The Wireless BM25 is capable of monitoring from one to fi ve gases through diffusion or sample draw. There are now 32 interchangeable “smart” sensor options available for the BM25 including PID, IR, electrochemical and catalytic sensors. Interchangeable/fi eld replaceable sensors provide the fl exibility of monitoring in a variety of applications thus reducing operating costs and downtime associated with instrument/sensor service.
When the BM25 detects a hazardous level of oxygen, toxic or combustible gas, the top-mounted beacon sends a fl ashing, bright signal in all directions while emitting a powerful, 103 dB siren alarm. If a BM25 goes into gas alarm, all BM25s in the network will report a corresponding alarm. Similarly, if one BM 25 fails a communication request then all the BM25’s in the chain will alert you of a fault, letting you get straight to the source of the problem. In all cases, the local gas detection capability remains effective and each BM25 will provide local alarm capability in the presence of gas.
The concave face design and construction ensures that gas sensors are protected and not blocked from the atmosphere in the event that the BM25 is knocked on its face or side in chaotic work environments. The IP66 ingress protection rating allows units to be used in harsh outdoor environments without damage from dust and water.
The operating runtime varies between 35 hours and 130 hours (depending on confi guration) and takes only 4 and a 1/2 hours to recharge. A safe trickle charger is also available for long-term area monitoring in classifi ed zones.

At Last, There is Such a Thing as a Free Lunch….
Anyone who has responsibility for health and safety in workplaces where the atmosphere could contain toxic or fl ammable gas, or a lack of breathable oxygen, should visit Telford’s International Centre on the 5th and 6th November 2014. The UK’s leading gas detection instrument companies and service providers will not only be exhibiting their latest products at the WWEM show, but will be presenting a series of seminars to bring visitors up to date with relevant regulations, working practices and technical developments.
Visitors who pre-register at
http://www.wwem.uk.com will gain completely free access to the exhibition and seminars, as well as free parking, free lunch and free refreshments throughout both days. Two days of free walk-in/walk-out workshop seminars on various aspects of gas detection in the workplace will help make this a must-visit event. The trade association CoGDEM (Council of Gas Detection and Environmental Monitoring) has helped to coordinate the seminars being presented by many of its member companies, so that the subjects covered will be educational, useful and interesting. The programme will be listed on the website shortly, so take a look then pre-register. And please stop at the CoGDEM display to say hello and congratulate us on our 40th anniversary this year.

New Guide to Gas Detection Published
A new independent Guide to Gas Detection has been published by CoGDEM (The Council of Gas Detection and Environmental Monitoring) to provide industry professionals with a complete reference document on the accurate, reliable measurement of gas concentrations in both process control and occupational safety applications.
This book provides the latest information on UK, EU and global regulations, guidance on flammable, toxic and asphyxiant gases, workplace safety, gas detection requirements, sensor technologies, calibration and performance evaluation.
“There is an emphasis on providing practical guidance throughout this book. For example, a quick reference guide explains the key issues in gas detection system selection, this book will be essential reading for anyone with a professional interest in gas detection.”
