SAFETY EFFECTIVE FIRE SUPPRESSION By Tarren Bolton | All images by Sandvik Ambatovy Nickel Mine in Madagascar, one of the biggest nickel mines in the world, has an enviable fire safety record. Plant Equipment & Hire looks at how Sandvik’s fire suppression systems are contributing to this. The success of the Ambatovy’s safety interventions speaks volumes for its policies and procedures and points to astute selection of fire suppression systems that are correctly suited to the kind of risks associated with its type of surface mining activities. F lammable liquids, combustible materials and extremely hot machinery combine to make the mine site a veritable tinderbox, and the hazardous and remote nature of mining puts mine sites at a high risk of fire. Not only is adequate fire protection a financial and regulatory necessity, but an ethical one too. Fire protection for the mining industry requires detailed assessments, planning and execution to meet the unique requirements of a site. Fire hazards differ for surface and underground mines and also vary according to a mine’s size, structure, materials, equipment and staff complement. And, while hazards vary from one site to another, common fire hazards can include mobile equipment and mining vehicles. Engaging a fire protection expert to conduct a detailed risk assessment can reduce the chance of hazards being overlooked. Ambatovy and Sandvik synergy Sandvik ECLIPSE Fire Suppression Systems are contributing to an enviable fire safety record at the Ambatovy Nickel Mine in Madagascar, one of the biggest nickel mines in the world. www.equipmentandhire.co.za With several mobile machines, as well as other risk areas protected by Sandvik Mining and Rock Technology’s ECLIPSE Fire Suppression Systems, Ambatovy has not lost plant equipment nor exposed onsite workers to hazardous fires since beginning production in 2012. The success of the mine’s safety interventions speaks volumes for its policies and procedures; and points to astute selection of fire suppression systems that are correctly suited to the kind of risks associated with its type of surface mining activities. Progressive approach According to Sandvik Mining and Rock Technology business developer for fire suppression, Nick Steinz, Ambatovy’s fire record is a good example of a mine’s management engaging with its supplier to adopt the right technology and systems to best protect its assets and, by implication, safeguard its people and production. “Our relationship with Ambatovy spans back to 2008 when their maintenance manager at the time first made enquiries about Sandvik’s ECLIPSE Fire Suppression Systems. Having used and seen our fire suppression systems in action while at a previous mine, he enquired about the suitability of our systems for plant equipment, pump houses and other at-risk equipment on the mine, which was still in the developmental stage. “Having met all the mine’s requirements, we won the supply tender and were able to supply systems for mobile earthmoving equipment including dump trucks, dozers, excavators, wheel loaders and graders, as well as pump engines and generators throughout the mine. Every new piece of equipment since then has also been outfitted with a Sandvik ECLIPSE Fire Suppression System,” he says. Foam extinguishing agent Steinz continues that Sandvik’s ECLIPSE Fire Suppression Systems use an entirely water-based foam system that attacks all aspects of the fire triangle (heat, fuel source and oxygen). A chemical chain reaction between these three elements results in fire, and a fire will burn for as long as all elements are maintained. The water-based foam system attacks all three. Clean-ups and recharging after triggering of the system is quick and easy, as opposed to powders, which can take AUGUST 2019 25
