LOUISVILLE, Ky. - Carbide Industries LLC, the largest domestic producer of calcium carbide, suffered a plant fire resulting in the death of two employees and halting production for what is expected to be an extended period of time. As a result, domestic supplies of calcium carbide, an essential component to acetylene, may be thin until Carbide Industries returns to production. This could impact the availability of acetylene.

basis for the next two months.

said MPS or MAPP gas are potential alternatives, but supplies for HVACR
applications may be very limited. Propylene is the most common alternative

significant backlogs on propylene containers. HARDI stated it is
continuing to monitor the situation.
