For approximately 40 years, unprotected or improperly protected penetrations have presented a subject of much concern to the fire-protection community. The arriving firefighters discovered several fires had broken out in five remote locations, filling many different areas of the building with smoke. According to the National Fire Protection Association's report on the fire, unprotected vertical and horizontal penetrations provided one of the major contributing causes of the rapid, erratic spread of smoke and fire. These openings allowed the smoke to spread beyond the electrical rooms and into occupied floors. Numerous fires similar to this one have emphasized the need for fire stopping the penetrations made by electrical installations. As a result of these fires, the respective committees developed requirements for both the building code and National Electrical Code NEC. These requirements insist on the installation of through-penetration fire stopping.
