Roof collapse studied to help protect firefighters. (News Briefs).NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. , in cooperation with the Kinston, NC, fire department, and the Bureau of Alcohol, Tobacco, and Firearms, conducted a house fire test in part to measure the deflection deflection /de·flec·tion/ (de-flek´shun) deviation or movement from a straight line or given course, such as from the baseline in electrocardiography. de·flec·tion n. 1. of the roof from ignition to collapse. The feasibility study The analysis of a problem to determine if it can be solved effectively. The operational (will it work?), economical (costs and benefits) and technical (can it be built?) aspects are part of the study. Results of the study determine whether the solution should be implemented. , funded by the U. S. Fire Administration, examined the potential to measure changes in roof position as an early warning technology for structural failure. Data from the tests are being analyzed and compared with other visual observation of fire conditions to determine if position measurements provide any significant additional information for making decisions about the safety of firefighters who might be on roofs to provide fire ventilation. Venting smoke though roofs is a common practice in fire fighting fire fighting, the use of strategy, personnel, and apparatus to extinguish, to confine, or to escape from fire. Fire-Fighting Strategy Fire fighting strategy involves the following basic procedures: arriving at the scene of the fire as rapidly as . It helps clear the smoke from structures to aid other firefighters entering the building. This study follows another conducted in cooperation with the Phoenix fire department to look at the use of thermal imaging as a means to warn about unsafe roof structures.
