SAFER PASSAGE FOR MOTORISTS AND PEDESTRIANS

B EKA Schréder supplied an energy-efficient LED lighting solution for the N1 Botlokwa Road Safety Project in the Matoks area. The key purpose of the project was to provide safety for pedestrians and motorists by reducing conflict zones through the introduction of pedestrian bridges and diamond interchanges. To provide safer passage for motorists and pedestrians through the area, lighting was essential and, having provided a uniform, com- pliant lighting installation, visual safety and easier visual identification of risks has been ensured. BEKA Schréder’s LEDlume-midi street light luminaires were selected to provide a compliant and efficient lighting installation and allow for effective transition lighting from dark surroundings to illuminated roads leading to the interchanges. Lighting of the area is key for the visibility of pedestrians and obstacles along the highway. BEKA LEDstream 19W LED floodlights were chosen for the aesthetic illumination of the arches of the two pedestrian bridges situated at either end of the project. The arches provide an aesthetic night time marker, while the indirect lighting effectively illuminates the bridge deck uniformly to provide pedestrians with safe passage over the N1 highway. The lighting design was by SMEC. BEKA Schréder locally develops and manufactures LED lighting products, designed

HKTDC HONG KONG INTERNATIONAL LIGHTING FAIR

LIGHTING FOR HAZARDOUS ZONES

T he 10 th edition of the HKTDC Hong Kong International Lighting Fair 2018 (Spring Edition) will be held from 6 – 9 April 2018 (Friday-Monday) at the Hong Kong Convention and Exhibition Centre on 1 Expo Drive, Wanchai. Empowered with decades of experience and expertise in organising trade exhibitions, the Hong Kong Trade Development Council is known internationally for its outstanding performance. Its trade exhibitions have been the distinctive platforms where both exhibitors and buyers alike explore business opportunities. At HKTDC’s world-class events where buyers and exhibitors from different countries and regions converge, the comfortable and convenient venue provides the ideal platform to negotiate business, exchange the latest market intelligence, and establish business contacts.

I f you operate a potentially haz- ardous working environment, it is up to you to ensure that workplace accidents are kept to a minimum. Statistics on work- place accidents in South Africa suggest that while only 10% of all accidents are the result of un- safe working conditions, 88% of incidents are the result of an em- ployee’s actions, or lack thereof. This could be due to negligence or poor instruction, or it could be that hazardous zones were not clearly marked. A big part of workplace safety is to ensure that dangerous areas are clearly marked, and one of the most effective ways to do this is with lighting. However, when combustible materials are present in the area, the light fitting itself could pose a potential risk of ignition. For this reason, when lighting is installed, the environment should be considered carefully. More about Hazardous areas As far as lighting is concerned, a hazardous zone is one in which a flammable substance is produced, handled or stored. In such areas, careful measures need to be taken to ensure that these substances are not accidently ignited. They can be outlined as follows: Zones 1 and 2 Zone 1 hazardous areas are those with the presence of high risk gases and vapours that create a potentially explosive environment. There is always a risk of a flam- mable mixture contaminating the atmosphere of the area, in which case a spark or heat source from any nearby lighting could act as a catalyst to disaster. Zone 2 areas are those with medium to low risk vapours and

gases, present in a form where they are unlikely to (but still could) combust, such as in store rooms. Zones 21 and 22 Zone 21 materials are those that take the form of powder or dust, and present a relatively high risk of creating an explosive or flammable atmosphere even during normal operations. Processing areas where these materials are likely to be pre- sent are extremely high-risk areas, and so require protected lighting that is safe to use without posing a risk of ignition. Zone 22 materials are those that would not normally be in the position of creating an explosive environment, but could still do so under the right conditions. Requirements for lighting in these areas Protected light fittings that are suitable for high risk areas (par- ticularly Zones 1 and 21), should always be Ex rated according to the hazardous classification into which they will be installed. That is to say, they should be safe to use and not cause an ignition source for gases or fibres in the air. They should also be dust or water re- sistant (minimum IP54) depend- ing on their intended use, and should be regularly inspected and maintained. Nordland Lighting is a leader in hazardous, industrial and commercial lighting. The company achieved ISO 9001:2015 and ISO 18 000 certification early in 2017. It provides project specific engineering design services to all its customers and its light fitting ranges are robust enough to meet the requirements of the mining and other industries in Africa and around the world.
