Mining is tough, gritty work. From underground shafts to open-pit operations, workers face dust, debris, heat stress, flash-fire risk and unpredictable conditions every single day. Big Bill builds flame-resistant gear that stands up to these realities. Our FR clothing is engineered to handle heavy abrasion, constant movement and long shifts in harsh environments, while keeping miners protected and comfortable. For full-coverage protection, our FR coveralls and work shirts are made with durable, arc-rated fabrics designed to resist wear in dusty, abrasive conditions. Strategic pocket placements keep essentials within reach, while reinforced seams help garments outlast the grind of daily mining work. When visibility matters, our CSA Z96 and ANSI 107 compliant high-visibility FR options help workers stay seen through haze and low light. Breathable FR base layers wick moisture to keep crews cooler in hot, confined spaces, while heavier layers and insulated FR outerwear deliver warmth during early-morning starts or cold-weather operations. From light shirts to rugged coveralls and bibs, every garment is designed to move with the worker reaching, climbing and bending through demanding tasks. All Big Bill FR products are arc rated and compliant with NFPA 70E, ASTM F1506 and CSA Z462 requirements, giving miners reliable protection shift after shift. Built for dust, built for durability, built to keep you safe underground and above.
