A firebreak or double track (also called a fire line, fuel break, fireroad and firetrail in Australia) is a gap in vegetation or other combustible material that acts as a barrier to slow or stop the progress of a bushfire or wildfire. A firebreak may occur naturally where there is an absence of vegetation or "fuel", such
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
Pilot lights were withdrawn because their continual small flame represented a waste of fuel. [1] Pilot lights required their own FSD, typically a thermocouple which held the valve open. [2] Regular testing of FSD is a part of routine maintenance for gas appliances. [3] Other safety devices may be fitted in addition to an FSD.
Schematic of a flame ionization detector for gas chromatography. A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ions per unit time makes this a mass sensitive instrument. [1]
A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area ...
Firehose on a fire engine that has one end connected to a pump outlet, and usually a nozzle on the other end. May also be a preconnected inlet hose (e.g., soft suction). Reduces steps at scene of fire. Pulaski A tool that combines an axe and a mattock in one head, similar to that of the cutter mattock, with a rigid handle of wood, plastic, or ...
An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...
An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
