A STUDY OF SMOKE MOVEMENT AND DETECTOR SENSITIVITY IN HIGH BAY HANGARS
This study sought to develop reliable data that fire safety and security management professionals can use in the development of models for smoke detector types and placement in high-bay hangar facilities. Two research questions were investigated, and hypotheses were tested in relation to each research question. The research questions investigated were as follows:
1. What effect does bay height have on smoke detector sensitivity in a high-bay hangar?
2. What effect does the use of a draft curtain have on smoke detector sensitivity in a high-bay hangar?
Each of the hypotheses was supported by the analyses of the data. The results of the research performed for this study found that, as bay height increases (all other factors remaining equal), smoke detector sensitivity decreases. The results of the research performed for this study found further that smoke detector sensitivity is higher when draft curtains are in place than when draft curtains are not in place.
Based on these findings it was concluded that the use of draft curtains should be mandated in all high-bay hangars. It was concluded further that means should be found to deploy smoke detectors at levels lower than ceiling height in bays higher than 15 meters.
