Formation and detection of hydrogen fluoride gas during fire fighting scenarios
نویسندگان
چکیده
Hydrofluorocarbon-based (HFC) fire extinguishing agents generate hydrogen fluoride (HF) gas [HF(g)] during thermal decomposition. Potential HF(g) exposure represents a health risk to any personnel not wearing proper Personal Protective Equipment (PPE) scenarios where HFC extinguishers are deployed. is harmful humans at vapor concentrations greater than 3 parts per million (ppm), with an Immediately Dangerous Life and Health (IDLH) level of 30 ppm. Controlled live-fire tests suppression confirm that produced greatly exceed IDLH levels within seconds demonstrate the need for real-time detection HF high very short time frames. Current commercial sensors limited in capability measuring phase, frame required prevent dangerous this toxic gas. This review provides comprehensive overview methods, including colorimetric, electrochemical, mechanical, optical sensors. The applicability sensor types complex environment event evaluated regarding response time, selectivity, saturation.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
DoS: Fighting Fire with Fire
We consider DoS attacks on servers in which attackers’ requests are indistinguishable from legitimate requests. Most current defenses against this class of attack rely on legitimate users in aggregate having more of some resource (CPU cycles, memory cycles, human attention, etc.) than attackers. A server so defended asks prospective clients to prove their legitimacy by spending some of this res...
متن کاملEradication of poliovirus: fighting fire with fire.
Endemic wild polioviruses have been eliminated from most of the world, and the number of human paralytic cases has been reduced by .99%, from an estimated annual incidence of .500,000 cases to ,2000 cases [1–3]. Circulating wild polioviruses remain endemic in only 2 major locations, Nigeria and a zone extending from northern India west to Pakistan and Afghanistan [1–3]. Furthermore, wild-type 2...
متن کاملFighting Fire with Agents
In this paper we propose a model for coordinating teams of computational agents. This model is especially aimed for coordinating agents performing in a simulated environment of forest firefighting, although it may be used in other domains. We will start by introducing the Pyrosim platform where we are carrying out our experiments. Pyrosim is a tool developed in our laboratory that simulates a f...
