Safeguarding the nation’s electrical health


MK Electric has revised its extensive suite of components dedicated to meeting the demands of the healthcare sector, delivering the highest standards of hygiene, safety and security. The portfolio includes anti-bacterial cable management, switches and sockets; Isolated Power Supply (IPS) sockets that meet MEIGaN (Medical Electrical Installation Guidance Notes); lockable and surge-protected devices and accessories dedicated for those with disabilities.


Anti-microbial hygiene in hospital, care home and other medical environments remains a considerable public and Governmental concern which MK Electric has addressed with two products with strong anti-microbial properties – Prestige 3D Antibac Blue, the anti-bacterial cable management solution for power and data distribution, and the market-leading Logic Plus wiring accessories range, which has now been demonstrated to possess significant anti-microbial properties. Together they offer a complete answer to the challenge of designing an entire installation that meets the requirements of an anti-bacterial specification. As the


trunking and wiring devices are both open to contact, the control of the spread of bacteria and infections can only be effective with such a complete solution. Prestige 3D Antibac Blue kills bacteria that can grow on surfaces such as trunking systems through a silver-based additive inherent within the PVC-u that fights organisms such as MRSA, and Klebsiella pneumoniae. Similarly, the Logic Plus range is manufactured from urea formaldehyde, a thermoset material that has similar properties to anti-microbial additives, and produced scratch-free – thanks to highly-engineered moulding tools – so there are no dirt traps where harmful bacteria may breed.


Independent tests showed that the Logic Plus range beat competitors in its anti-microbial properties against the four main ‘killer bugs’ that are now the main concern in hospital, care home and other medical environments. The range is 99.9% lethal to Methicillin-resistant


Staphylococcus aureus (MRSA), compared to 86.4% for similar competitive products; 98.9% lethal to Klebsiella Pneumoniae – compared to 95.4% for other non-MK offerings – and is also 99.9% fatal to E-Coli and Salmonella.


The MK MEIGaN IPS sockets meet the key recommendation that IPS outlets are double pole or un-switched; are ‘Clean Earth’ and are colour-coded blue with engraved white lettering stating ‘Medical Equipment Only’. Where white outlets are preferred; they should be mounted on a blue background, approximately 2cm larger than the socket; with the socket engraved ‘Medical Equipment Only’ in blue lettering. MEIGaN specifies an IPS in order to increase the supply resilience by reducing the impact of first fault conditions downstream of the IPS. The IPS is usually combined with an uninterruptable power supply (UPS) that prevents disruption of the supply owing to problems upstream of the UPS. www.mkelectric.co.uk


New ultra shallow foundation bollard system


A new ultra shallow foundation bollard system, that has a structural depth of only 75mm (3”), has been introduced by Tata Steel (formerly Corus). The Company claims this is the shallowest PAS 68-tested foundation bollard system available anywhere in the world.


The new Tata Steel Ultra Shallow Foundation (USF) bollard system is designed to provide a high level of protection from hostile vehicle attack. The prime purpose of the new shallow design is to avoid re-routing local underground utilities, which may need to be disturbed if deeper foundations are used. This shallow foundation means that excavation time is reduced and local disruption minimised.


Speed of installation of the system is one of its main benefits – up to 20 bollards per hour can be installed (dependent on ground conditions) making the system highly cost effective.


The product has been tested to PAS 68: 2010 standards, which in this case involved the system stopping a 7500 kgs truck impacting at 90 degrees at speeds of 64 kph and 80 kph.


The unique shallow foundation capability has been achieved by designing the base plate and the connection arrangement in such a way as to ensure maximum integrity of the system without the need for deeper foundations. The design also means that the system can be quickly installed with the minimum of preparation in locations where ground conditions are uneven – the


connectors enable the base plates to adapt to different gradients to ensure that the bollards are easily installed and aligned correctly. In addition, the design of the connectors means that, should the need arise, individual bollard

assemblies can be removed and replaced without the need to cut and repair reinforcement that is common to other bollard foundation systems.


Several bollard profiles and styles are available to suit differing client aesthetic requirements.


The Tata Steel USF bollard system is suitable for protecting from vehicle attack at a range of different locations. These include high profile sites where people gather together in numbers – shopping centres, sports stadia, airports and railway stations, large office developments and key public buildings. The system can be purchased separately for a stand-alone installation or can be specified as part of a larger scheme involving several elements of a complete site security plan. The USF bollard system from Tata Steel is the latest addition to the Company’s bollard system product line. This comprises several models in different styles and with different foundation arrangements, all of which are PAS 68 rated. A top-of-the-range high performance bollard system that delivers zero penetration from a 7500 kgs truck impacting at 90 degrees, and at up to 80 kph, is also available.
