Author(s) : SEMPLE J. B., BRUCE D. O.

Summary

PRIORTO 1975, NFPA 90 A, STANDARD FOR INSTALLATION OF AIR CONDITIONING AND VENTILATING SYSTEMS, HAD A PARAGRAPH TITLED < WHERE FIRE DAMPERS ARE REQUIRED >. IT WAS A SIMPLE, BASIC APPROACH BUT WAS COMPLICATED BY MANY EXCEPTIONS AND REFERENCES TO OTHER CHAPTERS. THE USE OF CEILING DAMPERS WAS BECOMING WIDELY ENFORCED AND THERE WAS FREQUENT CONFUSION AS TO WHETHER A FIRE DAMPER WAS REQUIRED OR COULD BE USED IN A CEILING, OR WHETHER A DIFFERENT DEVICE WAS NEEDED.
