SAFETY hours to clean and may render a machine or entire area inoperable for an entire shift. Steinz explains that if a mine does its own general breakdown recharges and system repairs, then they would be responsible for the clean-ups and recharges and Sandvik would do the scheduled servicing. In the event of a serious fire the foam- based solution has other advantages, including having a cooling effect which can prevent reignition. It is also able to extinguish the fire without hampering visibility as is the case with powders, which makes it safer and easier to evacuate an area in the event of a serious fire. Furthermore, the foam is not harmful to the environment, is biodegradable, non-toxic and is suitable to be used on all diesel-powered equipment. “Our client also trusts the failsafe triggering ability of our devices, which is kept under pressure and will only activate in the event of a loss of pressure caused by special sensor tubes detecting excessive heat in the presence of fire or when activated manually. Being stored under pressure also provides an additional failsafe when the operator checks the gauges at the beginning of each shift.” Training Training staff is an essential step in protecting people and property against fire, and an appropriate response to fire can save lives and reduce damage. As with the rest of a fire protection plan, fire safety training should be tailored to the unique requirements of a mine site and its staff. “We offer ‘Grey Card’ training, which empowers the clients to do their own breakdown repairs and recharges to minimise their production downtime. Training consists of classroom theoretical training as well as practical, hands-on training,” says Steinz. In addition, Sandvik offers training to equipment operators to ensure that they: • have a basic understanding of how the system works; • know what fire system pre-startup checks to carry out; • understand what to do in the event of an on-board fire; • know what happens when the system activates automatically; • can activate the system foam discharge manually; • know what happens when the system is activated manually; and • are aware of post-fire risks and recommended procedures. Fleet safety In terms of fleet safety it is critical to have fire suppression systems in place to prevent the loss of a machine and give the operator time to safely exit the machine and move to safety. Sandvik ECLIPSE fire suppression foam. 26 AUGUST 2019 Ambatovy’s Mobile Equipment maintenance manager says that in terms of fleet safety it is critical to have fire suppression systems in place to prevent the loss of a machine and give the operator time to safely exit the machine and move to safety. The system also needs to be flexible enough to be used on different types of machines and robust enough to remain functional in typically tough mining conditions. Dealing with a company like Sandvik Mining and Rock Technology also provides reassurance that systems are properly configured to cover all risk areas on a machine and that aftersales service and qualified support are available to ensure the systems stay in good condition and are tested regularly. While appropriate fire protection equipment is vital, it is rendered useless if not in proper working order. Equipment should be regularly inspected, maintained and repaired or replaced as necessary. Equally important is the company’s ability to provide sufficient parts and spares, while also being in a position to outfit new machines as required as was the case recently when 78 earthmoving machines were added to Ambatovy’s fleet. www.equipmentandhire.co.za
