* WHO :* WVU Fire Service Extension instructors, local fire fighters

* WHAT :* Media are invited to observe the two-story, 53-foot-long mobile fire training unit of the WVU Fire Service Extension this weekend at a fire school. When they enter the burn unit, firefighters from Putnam, Kanawha, Cabell and surrounding counties will be challenged by the sights, sounds, obstacles and flames of commercial and residential structural fires. The sessions will be led by WVU Fire Service Extension instructors. The safe system is controlled from an observation room by a lead instructor who can shut down the operations and ventilate the units interior within 45 to 60 seconds. Environmentally sound, the unit is fueled by clean-burning propane. It generates benign smoke that does not disturb the community.

* WHEN :* The high-tech unit will be the focus on Saturday and Sunday, May 5-6. Saturdays sessions run from 10 a.m.5 p.m. Training resumes Sunday at 9 a.m. and concludes at 3 p.m.

* WHERE :* Putnam Career and Technical Center, Route 62, Eleanor, W.Va.

* NOTES :* Contact Murrey Loflin, director of WVU Fire Service Extension, to arrange media assistance at the fire school. More information about the unit and the WVU Fire Service Extension will be available at the training.
