Smoke control systems

摘要

While we endeavor to prevent, minimize, and control the occurrence and severity of fires by installing sprinkler systems, minimizing the use of combustible materials in construction, and minimizing ignition sources, fires still occur and lives are still lost. By now, we all know that it is the smoke (carbon monoxide and other products of combustion) that is the greatest threat to life in the event of a building fire. While the fire may be localized, the smoke will travel wherever the building airflow and its own buoyancy will take it. Without safeguards, smoke will travel through ductwork, up through building shafts, through openings in walls and floors, and throughout open atria spaces and open malls.
