WHP Training Towers' engineers have developed the WHP Modular Training Simulator (WHP "911" TRAINER), designed to provide a multi-level simulator while staying within federal guidelines for the grant program. The movable trainer is a two-story tower with attic and sloped roof alongside a single story annex housing a live fire burn room. It may be set on any suitable surface and relocated as needed with the use of commercially available equipment. Design for the WHP "911" TRAINER is based upon a tower developed for the U.S. Army. The WHP TRAINER is weather-tight and designed to require minimal maintenance. The structural skin is 18 gauge steel. Stair stringers and railings are heavy-duty welded structural steel and meet OSHA requirements. A single sloped roof with chop-out and rappelling anchors provides for a realistic roof operations training.
