Phos-Chek long-term fire retardants, Class A foams, and water enhancing gel are the world’s leading chemical solutions for managing wild land, industrial and municipal fires. In 1962, the Phos-Chek name was born and an era of innovation and partnership began. For several years before and for four decades since, we have worked side-by-side with fire management agencies in North America and across the world to provide safe and effective firefighting chemicals to meet the needs and desires of fire management personnel.
