halon is use in a fire fighting system. The problem is that the bromine content in Halon media is giving potential to ozone depletion.
Before we start, let's clear something up: The storage, use and sale of RECYCLED Halon is not illegal. In fact, it is encouraged, and many professional fire protection services companies specialize in Halon recycling and recharge. That said, the production of NEW Halon was outlawed in 1994 under the Clean Air Act. Halon is a potent CFC and is very damaging to the atmosphere. However, since their is no known method of disposing of existing Halon supplies (and since it is such a powerful fire suppressant), recycled Halon is still a popular means of controlling fires in many commercial applications. Fun fact: the FAA requires Halon use on all commercial airlines!
The gas discharge fire suppression system uses Halon gas or an EPA-approved gas to replace Halon. Halon interferes with the fire's chemical combustion and does not harm computer systems, which made it a popular solution. Halon was banned in 1994, when it was discovered that it was an ozone depleting gas; however, some of these systems still exist. The replacements, known as clean-agent fire suppression systems, are carbon dioxide, argon, Inergen, and FM200.
Halon, CO2, Neon,Nitrogen
Halon is harmful to the ozone layer as it contains chlorine and bromine atoms, which deplete ozone molecules. Due to its significant ozone depleting potential, halon has been banned by the Montreal Protocol to protect the Earth's ozone layer. Its production and use are restricted to specific critical applications such as aviation and military where no suitable alternative exists.
CFCs, also known as chlorofluorocarbons, are typically not used anymore for extinguishing fires due to their harmful impact on the ozone layer. Instead, other fire suppression agents like halon, CO2, or clean agents such as FM200 are commonly used. These alternatives are effective in suppressing fires without the ozone-depleting effects of CFCs.
A halon extinguishing system can be removed when it is no longer necessary for fire protection, typically after a thorough risk assessment. This may occur if the protected area is no longer at risk of fire hazards that halon is designed to combat, or if alternative, environmentally-friendly fire suppression systems have been installed. Additionally, compliance with regulations and guidelines regarding halon use and disposal must be followed during the removal process.
They use their knowledge and they use EPF spyphone
To deoxidize something, you can use chemical agents such as reducing agents (e.g., hydrogen, carbon) or by heating the material in a controlled environment with limited oxygen supply. This process helps to remove oxygen atoms from the surface of the material, reducing its oxidized state.
I Stictly told you not to do that. (strictly- strongly recommended)
"Be quiet!",the teacher instructed us strictly.
That's an environment where you'd most likely see a halon system in use.
