Flash fire research

This Webcast will discuss the recent advances in protective performance testing of flame resistant clothing, focusing on new groundbreaking research on the duration and energy of actual hydrocarbon flash fires outdoors. This research was able to quantify how long these events last and how much energy they release, and HD video of the work will be used extensively. 

Further research should be conducted toward establishing a better means to categorize the true fire hazard of all flammable and combustible liquids. The flash point, and in some cases boiling point, are measured values that are used for the current classification system. Additional properties, such as viscosity, dissolved combustible solids, and heat of combustion or heat release rate data should be included in a more comprehensive system. 

Research the Internet and find a PowerPoint presentation about fire detection systems or the toxicity of smoke. Download the presentation to a flash drive or CD and bring it to class to be presented by yourself or the instructor. Cite your sources. 

The lowest temperature of a flammable liquid at which it gives off sufficient vapor to form an ignitable mixture with the air near the surface of the liquid or within the vessel used. The flash point has been commonly determined by the open cup or closed cup method (ASTM D 56, Standard Test Method for Flash Point by Tag Closed Cup Tester, ASTM D 92, Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester, ASTM D 93, Standard Test Method for Flash Point by Pensky-Martens Closed Cup Tester ASTM D 3278, Standard Test Method for Flash Point of Liquids by Small Scale Closed Cup Apparatus, ASTM D 3828, Standard Test Method for Flash Point by Small Scale Closed Cup Tester), but recent research has yielded higher and lower flash points depending on the surface are of the ignition source. 

Lower explosive limit the lowest concentration of a substance that will produce a fire or flash when an ignition source is present, expressed as a percent of vapor or gas in the air by volume Low-level waste radioactively contaminated industrial or research waste such as paper, rags, plastic bags, medical waste, and water-treatment residues Lumbar the section of the lower vertebral column immediately above the sacrum, located in the small of the back and consists of five large lumbar vertebrae...
