Case Study: Montana Limestone Company achieves doubled productivity and a 25% revenue gain with HSI's on-demand MSHA Safety Training System

Montana Limestone Company - Customer Case Study

Montana Limestone Company, a leading limestone quarry operator and subsidiary of Dakota Coal Company, faced rising MSHA compliance demands and heavy costs from traditional classroom training that required shutting down operations. With an aging workforce and MSHA requirements for 24 hours of initial and 8 hours of annual refresher training, the company needed a more efficient, accountable approach and engaged HSI to deliver on‑demand MSHA training via HSI’s Safety Training System.

HSI moved Montana Limestone’s program online with short, interactive on‑demand courses, mobile access, virtual live MSHA sessions, and automated tracking and reporting tailored to the mine’s needs. As a result, Montana Limestone roughly doubled productivity, realized an estimated 25% revenue gain, and avoided the ~2,600 tons (about $20,000) of lost production per day previously spent on live classes, while gaining real‑time training metrics and easier regulatory reporting thanks to HSI.
