In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe. The pipe is usually covered with thermal insulation to retain heat losses ...
Operating temperature. An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum ...
Stovepiping. In intelligence gathering, stovepiping is the presentation of information without proper context. It can be caused by the specialized nature or security requirements of a particular intelligence-collection technology.

It is outflow from San Antonio de los Buenos, Tijuana's broken-down sewage treatment plant. Mexico says a new $33.3 million plant under construction is scheduled to come online by Sept. 30. For ...
When a hot ember ignites the nests, the fire can be just as serious as one caused by ignition of soot. In very old houses, the chimney may also be very large and thick enough to withstand the fire. The high temperatures may affect the strength of the chimney causing distortion of metal structures, and potential failure of ceramic structures.
When the AFA petitioned the US Secretary of Transportation to set a federal limit for cabin temperatures during boarding of 80 F (26.7 C), or 85 F if in-flight entertainment screens are switched ...
