The majority of guidance available for design of heat and smoke building vents installed in buildings is restricted to nonsprinklered, single-story buildings. [4] This is partly a historical consequence of the installation of heat and smoke vents following the August 1953 General Motors, Livonia, MI major fire in a nonsprinklered manufacturing facility which effectively stopped the production ...
Round duct is made using a continuous spiral forming machine which can make round duct in nearly any diameter when using the right forming die and to any length to suit, but the most common stock sizes range evenly from 4" to 24" (10-60 cm) with 6"-12" (15-30 cm) being most commonly used. Stock pipe is usually sold in 10' (300 cm) joints.
Vertical ventilation takes place through holes cut in the roof, typically by truck companies during the early stages of a fire in a process known collectively as roof operations, while horizontal ventilation usually takes place through doors and windows. The goal of each is to clear heat and smoke to increase chances of survival for trapped ...
A typical system incorporates a series of disposable or cleanable pre-filters, a disposable vee-bag or cartridge filter. HEPA or carbon final filter modules can also be added. Various models are available, including free-hanging or ducted installations, vertical or horizontal mounting, and fixed or portable configurations.
HCCS – horizontal clamp connection system; HCM – horizontal connection module (to connect the christmas tree to the manifold [citation needed]) HCS – high-capacity square mesh screens; HD – head; HDA – helideck assistant; HDD – horizontal directional drilling; HDPE – high-density polyethylene; HDT – high-resolution dipmeter log
Valve guard – A fitting (cap or collar) screwed or clamped to the shoulder, defending the valve from impact during transport, and in some cases, when in use. [ 1 ] Permanent markings – Information identifying the cylinder and its specification, stamped into the outside of the shoulder on metal cylinders. [ 5 ]

A single installation point is simpler, requires less maintenance and is less prone to errors. Commercially available optical flowmeters are capable of measuring flow from 0.1 m/s to faster than 100 m/s (1000:1 turn down ratio) and have been demonstrated to be effective for the measurement of flare gases from oil wells and refineries, a ...
