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.
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.
Restaurants and commercial kitchens are notoriously one of the largest consumers of energy per unit of floor area. Moreover, the kitchen ventilation system is often the largest energy-consuming component in a food service facility.
This month's Facility Files will focus on the Back2Basics test addressing the renovation of an existing Metro station with the addition of a new smoke evacuation system located within the building and within the subway’s inbound and outbound tunnels. The associated ADA-compliant elevator will have its own stand-alone, engineered, smoke control, 100 percent outside air fan to a positive-pressurized elevator shaft system.
Whether we’re talking a single building or a larger campus, proper strategy for this key HVAC component requires the right team working at the right times. Both physical and fiscal safety may depend on it.
According to Det-Tronics, its SmokeWatch™ U5015 uses advanced photoelectric smoke detection technology not generally available in an explosion-proof housing. The detector is rated for Class 1 Division 1, 2, and Zone 1 environments found in industrial applications. Used with the Q5016 Duct Mount Accessory, the detector can be installed on ductwork to meet NFPA 90A requirements for AHUs of more than 2,000 cfm.
The codes, personnel, and terms related to the commissioning process for health care may seem to leave room for confusion. The authors delineate the differences for you here because, especially when it comes to these settings, no such room exists.
Life safety design on campus is hardly an academic exercise, but systems built to comply with older codes often get stuck in a senior slump. Execute a smart assessment to identify your upgrade options.
Engineered Systems magazine’s September 2019 issue questions the need for multiple building codes that cover the same subjects, examines the dos and don’ts of power systems for critical facilities, offers tips on how to select the proper centrifugal pump circuit flow controls, and much more.
