Abstract
Thirteen additional preservative-fire retardant systems were applied to Ponderosa pine and evaluated for flammability both before and after water leaching. The more promising four systems were given a thorough evaluation for flame spread, toxic gas and smoke density levels, resistance to decay, and compressive strength. The most promising system on the basis of history of usage in the mine, ease of application, and low cost as well as overall performance is the fyreprufe-acc albi 107a-144 combination. A survey of inspection tools and instruments, identified equipment that could be assembled into an inspection kit for use in determining the extent of decay and/or impregnant retention levels in mine timber. A literature search identified those high fire hazard areas found in a typical mine. Timber and other wooden structures used in such areas should be treated with an acceptable fire-retardant system. A survey of insurance companies revealed that the use of such treated timber in the mines would probably have little or no impact on the rate structure.
