With the 2019 editions of NFPA 80 and NFPA 105 came the allowance for remote periodic testing of smoke and combination fire/smoke dampers. For building owners, this can mean significantly reduced costs and increased safety.
Chapter 7 of the International Building Code (IBC)1 requires life safety dampers to protect duct and air transfer openings within building separations — fire walls, fire barriers, fire partitions, horizontal assemblies, smoke barriers, and smoke partitions.
Picking up from my last article in the June 2019 issue, I will explore some context for real-world life safety applications. In this article, I’ll focus on complying with NFPA 99 (Section references to 2018 ed.) and its referenced standards as resources for your health care facilities’ HVAC designs.
A devastating event doesn’t always originate from a natural disaster. At any moment during construction or operation, something could go wrong — and it will.

As the demand for electrical power increases, distribution systems are expanded to accommodate the increased demand. Stiffened transmission systems, increased substation capacity, and added on-site and distributed generation all contribute to increases in available fault currents.
Picking up from my last article, “Smoke Control Infrastructure Pitfalls” (December 2018), we will explore some context for real-world smoke control applications with a focus on using NFPA 92 as a resource for your smoke control rational analysis development in this article.
Code and regulations require that LEL concentration of hydrogen (H2) be limited to 25% of LEL or 1% of room volume. The room ventilation method can be either forced or natural and either air conditioned or unconditioned.
