Hi,
Halon is a liquefied, compressed gas that stops the spread of fire by chemically disrupting combustion.Halon is an extraordinarily effective fire extinguishing agent, even at low concentrations. A key benefit of Halon, as a clean agent, is its ability to extinguish fire without the production of residues that could damage the assets being protected.
I know a site named Halon.us which buy damaged halon extinguisher from public.
What else can I help you with?
What is the concentrations that have been reduced as a result of the Montreal protocol?
The Montreal Protocol has led to the reduction of concentrations of ozone-depleting substances such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons. These substances have been phased out gradually to protect the ozone layer and mitigate the risk of harmful effects on human health and the environment.
What allotrope of this element is being depleted from earth's stratosphere?
The allotrope of oxygen being depleted from Earth's stratosphere is ozone (O3). Ozone depletion is primarily caused by human-made chemicals like chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the atmosphere. This depletion leads to the formation of the ozone hole, allowing more harmful ultraviolet (UV) radiation to reach the Earth's surface.
If the world was to ban from cfc's who would this law effect?
CFCs are pretty much banned by the Montreal Protocol . HCFCs are being replaced as well except for medical inhalers etc. and fire extinguishing Halons in aircraft and submarines. The regulation affected all users.
What are the primary greenhouse gases released to the atmosphere by humans?
Carbon Dioxide released by the burning of fossil fuels and deforestation. (CO2 contributes 61% to global warming) Methane released from agriculture, and biological activities, including decomposition at landfills. (Accounts for 15% of global warming.) Chlorofluorocarbons (CFCs) are man-made chemicals used in refrigerators and other industrial applications. (Accounts for 12% of global warming). Nitrous oxides from fertilizers and fossil fuel burning (4%) Others: ozone, halons, water vapour (8%) *from Callan, S.J. and J.M. Thomas. 2000.

What is the big hole created by the hazardous gases in the ozone layer?
It's called the ozone hole, though it's actually more like an extreme thinning of the layer of ozone. Ozone is a molecule with three atoms of oxygen instead two. The oxygen gas is a molecule of two atoms of oxygen. But ozone is not so. These ozone molecules are able to arrest the UV radiations those coming from preferably from the sun and re radiate in some other form of energy which are not harmful to the living structures. These ozone molecules will get spoiled by the gas called freon which is being used as refrigerant in case of air conditioning units and refrigerators. The freon is known to be Tri chloro fluro Carbon. If we replace freon by any other refrigerant then this drastic problem can be solved once for all. So let us try to discover such a one soon.
Do halons and CFC's both destroy ozone in the stratosphere?
Yes they do. Halons and CFC's both destroy ozone.
Which chemical are controlled by the Montreal Protocol?
Halons
Do halons contain halogens that are highly reactive with oxygen?
Yes, halons contain halogens such as bromine, fluorine, or chlorine, which are highly reactive with oxygen. This property allows halons to be effective in fire suppression by chemically interrupting the combustion process. However, the use of halons has been largely phased out due to their ozone-depleting properties.
How halons causes ozone depeletion?
Halons contain chlorine and bromine atoms which, when released into the atmosphere, can react with ozone molecules. These reactions lead to the breakdown of ozone molecules, causing ozone depletion. Halons are potent ozone-depleting substances and are now heavily regulated under international agreements to help protect the ozone layer.
Why is halon harmful for ozone layer?
Halons are harmful for ozone. They also react with ozone to deplete it.
What do Halons and CFC s do to the ozone A inhibit ozone formation B cause ozone formation in the troposphere C destroy ozone in the stratosphere D cause excess ozone formation in the stratosphere?
Halons and CFC s both destroy ozone in the stratosphere.
Halons contain halogens which are highly reactive with oxygen?
Up until "with oxygen" you were doing so well, though it should be emphasized that while halogens are quite reactive generally, halons are pretty inert. Halons which reach the upper atmosphere could break down under ultraviolet light, releasing halogen radicals, for which "highly reactive" is far too mild a term. However, they don't really do much with diatomic oxygen (though they do catalyze the decomposition of ozone into diatomic oxygen).
How much fuel does a cat 966 use per hour?
7 halons per hour
What are halans causing ozone depletion?
Halons are a class of chemical compounds that contain bromine and chlorine, which are known to deplete the ozone layer. When halons are released into the atmosphere, they can break down ozone molecules, leading to a reduction in the concentration of ozone in the stratosphere. This depletion of the ozone layer can have harmful effects on human health and the environment by allowing more harmful UV radiation to reach the Earth's surface.
Which pollutants affect the ozone layer?
Chlorine and bromine in the man-made gases like halons and freons (CFCs).
What type of things destroy the ozone?
All the things containing halons destroy it. Chlorine, Fluorine etc are the destroying elements.
What are the chemicals that are being blamed for the destruction of the ozone layer?
one of the chemicals that are being blamed for the destruction of the ozone layer are chlorofluorocarbons.and the halons
