INTELLIGENT BRANDS // Cabling POWERED BY Judging the safety of your cabling standards ///////////////////////////// P is also potentially more stringent than the containment that is holding it. erhaps one of the most overlooked elements of Information Technology is also one of the most under- appreciated. How well your cabling infrastructure performs has a massive impact on the speed of your network and your ability to please your customers. We spoke to industry experts asking for their opinions on two cabling topics. Furthermore, in the UK and some other countries, there are local electrical regulations. Those in the UK dictate how a cable is installed to prevent a premature collapse in the event of fire. NARENDER VASANDANI, RCDD, TECHNICAL MANAGER MIDDLE EAST AND INDIA AT SIEMON How can the safety standards of cabling infrastructure be judged? OSAMA ABED, TECHNICAL MANAGER (GULF, MIDDLE EAST, EAST AND SOUTH AFRICA), NEXANS CABLING SOLUTIONS Safety is a top priority in the IT industry and in structure cabling. Safety needs to be ensured in two parts that require careful consideration by the installers. Part one is the safety of products themselves, where each component of the structured cabling products has special considerations for the safety. For example, cables jackets should be LSZH (Low Smoke Zero Halogen) instead of the conventional PVC plastic cable jackets, since LSZH is safe to humans in case of fire while PVC is toxic. Nexans has ensured that all cabling solutions and cables used for indoor operation, including copper and fibre optics cables and patch cords, have LSZH jackets to ensure human safety in case of fires. The second part is the safety of operation. In copper cables, for example, and since the majority of new installations utilise different grades of Power-over-Ethernet (PoE) technologies, it is very important to test the components of the copper cabling solution and ensure that they are designed to prevent accidental exposure of people to PoE powers to avoid the risk of electrical shocks. This is accomplished by implementing robust www.intelligentcio.com Osama Abed, Technical Manager (Gulf, Middle East, East and South Africa), Nexans Cabling Solutions insulation in the components, in addition to providing certain grounding techniques, which are incorporated in the components’ design to ensure that these products are grounded correctly to prevent the electrical hazards and other issues that can result from improper grounding. PAUL CAVE, TECHNICAL PRE-SALES MANAGER, EXCEL This is very much down to local and regional regulation and codes. One example in Europe focuses on cables that became part of the revised CPR, Construction Products Regulation, which goes much further than the IEC 60332–1 flammability rating. Now there are a number of different additional requirements to consider, because it is legally binding and enforceable, the data cable has a new reaction to fire classification that it has to adhere to. It is not only more stringent than before, but it On-the-job safety, whether for the independent cabling contractor or for the cabling technician working for an enterprise, must be an integral part of everyday routine. Although cabling installers are responsible for observing general construction safety standards like all other workers, their main areas of concern will be electrical and low- voltage safety. A KEY TO EFFECTIVE SAFETY PROGRAMMES IS WORKER TRAINING. Electrical safety is a major concern of the National Electrical Code (NEC), which is published by the National Fire Protection Association (NFPA). The NEC accomplishes this purpose, not by outlining specific safety procedures, but by describing safe and effective equipment and procedures. A key to effective safety programmes is worker training.
