Innovation in Safety: The Development of Mobile Lightning Shelters for Field Staff
In an ambitious environmental and safety initiative, Anglogold undertook the reprocessing of Johannesburg's old mine dumps, also known as slimes dams, to extract the remaining gold left by older processes. This project not only represented a significant step in mining technology but also highlighted a commitment to environmental sustainability and worker safety. The introduction of mobile lightning shelters emerged as a critical component of this initiative, addressing the unique challenges posed by the vast and exposed operational fields.
The reprocessing of slimes dams involved creating large fields covered with stabilizing vegetation to mitigate dust blow-off during high winds, alongside cultivating corrosion-resistant walls. This extensive operation required teams to cyclically work across the expansive slimes dam surfaces, necessitating a reliable safety solution against the frequent lightning storms in the area.
Given the large distances between operational zones and the inherent mobility of field staff, traditional lightning protection measures were inadequate. A dynamic solution was needed to ensure the safety of the staff against the sudden onset of lightning storms, a common hazard in the region.
Anglogold, in partnership with Power Quality Consultants (PQC), developed mobile lightning shelters equipped with a novel Lightning Safe Mounting System (LSMS). These shelters were designed to be easily relocatable, providing immediate refuge for field staff during lightning events. The shelters’ mobility allowed for continuous operation across the vast slimes dams without compromising on safety.
The mobile shelters featured a retractable mast system, which, despite a few instances of damage due to mishandling, showcased PQC's solution's durability and effectiveness over two decades. The shelters' design prioritized ease of use and safety, with the LSMS allowing for secure mounting even under the threat of lightning, thus minimizing operational disruptions and enhancing safety protocols.
Integral to the success of the mobile lightning shelters was a comprehensive staff training program, ensuring all field personnel were adept at deploying the shelters safely and efficiently. This focus on training underscored the project's holistic approach to safety, combining innovative engineering with human factors to safeguard the workforce effectively.
Anglogold’s initiative to reprocess slimes dams not only represented a significant advancement in mining and environmental management but also set a new standard for operational safety in high-risk environments. The development and implementation of mobile lightning shelters exemplified how innovative solutions and a commitment to safety could coalesce to protect lives while advancing industrial and environmental objectives.
The project serves as a benchmark for the mining industry and beyond, demonstrating that with the right combination of technology, training, and commitment, it is possible to tackle the dual challenges of environmental sustainability and worker safety. As industries worldwide grapple with similar challenges, the lessons learned from the implementation of mobile lightning shelters offer valuable insights into the potential for technological innovation to drive safety and environmental stewardship.
