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.
Flame ionization detectors are used very widely in gas chromatography because of a number of advantages. Cost: Flame ionization detectors are relatively inexpensive to acquire and operate. Low maintenance requirements: Apart from cleaning or replacing the FID jet, these detectors require little maintenance.
Pilot lights were withdrawn because their continual small flame represented a waste of fuel.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.
TS 54 -14 is a technical specification (CEN/TS) for fire detection and fire alarm systems (Part 14: Guidelines for planning, design, installation, commissioning, use, and maintenance). Technical Committee CEN/TC72 has prepared this document as part of the EN 54 series of standards. This standard was published in October 2018. [3]
A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.
A fire in an oxygen tube approaching an oxygen firebreak. An oxygen firebreak, also known as a fire stop valve or fire safety valve, is a thermal fuse designed to extinguish a fire in the delivery tube being used by a patient on oxygen therapy and stop the flow of oxygen if the tube is accidentally ignited.
By definition, an automatic fire suppression system can operate without human intervention. To do so it must possess a means of detection, actuation and delivery. In many systems, detection is accomplished by mechanical or electrical means. Mechanical detection uses fusible-link or thermo-bulb detectors.
