IMPACT-RESISTANT DRYWALL IMPACTS FIREFIGHTING OPERATIONS

摘要

During recent months, fire service publications and Web site articles have expressed concern about Hi-Impact~® brand impact-resistant wallboard. Concerns include difficulty in breaching it for firefighter rescue and the combustibility of the Lexan~® (polycarbonate plastic) laminated to the back of sheets of this type of wallboard. My part-time job as a construction company safety director allows me to observe closely developments in building materials and construction methods. The Hi-Impact~® brand wallboard is only one of many brands of specialty drywall board that are classified as "impact resistant."
