Gaseous fire suppression refers to the use of inert gas and certain chemical agents to extinguish fire. It is also often termed as Clean Agent Fire Suppression. The use of this method in extinguishing fire is presided over by the NFPA Standard for Clean Agent Fire Extinguishing Systems.
The fire suppression system makes use of an agent, agent storage containers, fire detectors, agent release valves, fire detectors, dispersion nozzles and agent delivery piping. It also makes use of fire detection systems such as actuation signaling and wiring control panel. In few cases, the agent can also be delivered through a solid propellant gas generator that can give off chemically active gas or inert gas.
To be able to extinguish fire, there are four specific ways on how agents work on a fire suppression system. These methods combined are better known as the Fire Tetrahedron. Here are the four methods of extinguishing fire along with their representative agents.
1. Reduction/ isolation of fuel- in this step, no agents are used as primary source of fire control. 2. Reduction of heat
HFC-227ea (MH227, FM-200)
Novec 1230
HFC-125 (ECARO-25)
3. Reduction/ isolation of oxygen
CO2 carbon dioxide
Argonite / IG-55 (ProInert)
IG-541 Inergen
IG-100 (NN100)
4. Inhibition of chain reaction of components mentioned above
FE-13
FE-227
FE-25

FM-200
Halons
Halon 1301
Freon 13T1

Triodide (Trifluoroiodomethane)
Application: Generally, there are 2 methods on how to apply an extinguishing agent. You can either do total flooding or local application.
Total flooding- systems that work on total flooding applies extinguishing agents to a 3-dimensional enclosed area. The agent is allowed to be concentrated to reach a certain volume percentage of the agent in air. When the specific volume is reached, it is already adequate to put off a fire. Such systems are operated automatically using detection controls. It can also be operated manually using a system actuator.
Local application- systems working in this type of method applies extinguishing agents directly to the fire using a 2-dimensional are or a 3-dimensional region that surrounds the object on fire.
The difference of these two methods is that total flooding does not have physical barriers that encloses a fire space while local application does. When using automatic extinguishing systems, the term local application does not mean that the fire suppression system is using wheeled machines or portable fire extinguishers.
Safety precautions
Suffocation
Carbon dioxide, which is one of the primary representative agents of a fire suppression system, can present a health risk when in an enclosed space. Suffocation is one of the primary effects of inhaling carbon dioxide. There are many incidents where people are killed by the release of carbon dioxide. To prevent suffocation, safety systems should be installed as soon as a warning alarm is turned on in case of fire. The warning should be either a loud siren or something visually seen so that people can be aware of the presence of carbon dioxide, especially in an enclosed area. Evacuation of the area should be implemented. Proper awareness of the effects of carbon dioxide and maintenance of fire extinguisher systems should also be taken care of to ensure safety. Barotrauma, the pressure that is caused by the release of extinguishing and inert agents, including IG-100, IG-55 and IG-55, can actually be enough to break windows, and even walls. It can also harm people and other properties. Proper precaution is advised.
Our homes are our havens and when we are in our homes we need to feel safe and secure. Locks help assure nobody comes in and gas and smoke detectors help protect us from within our homes assuring that if a gas leak or fire occurs we know about it soon enough to get to safety. Everybody should have a gas detector and a smoke detector in their home; it's as simple as that. If for some reason you don't have a gas detector or your gas detector is old then perhaps you could use a little help in what to look for when buying a gas detector.
First of all, check to see how many gases the gas detector can detect. Most people just need a gas detector capable of detecting carbon monoxide however if you live in an area where you may be potentially exposed to more gases you will certainly want a gas detector capable of picking up all of those. Just make sure you know what you need so you will know what to shop for.
Another important aspect of a home gas detector is battery life. You will want a detector that runs on batteries and that has a long life. If the battery life is too short and your gas detector dies then it won't be protecting you. Make sure your home gas detector has an alarm, light, or something of that nature that goes off when the battery is dying so that you will know to replace it.
If you live near a landfill, refinery, power plant, or anything of that nature then a Minirae gas detector system will alert you at any time there are unsafe levels of gas in the air. There is nothing wrong with taking precautions to ensure you and your family are safe and RAE Systems has a variety of gas detectors for your home that will allow you to sleep well at night.
In this day and age we should not rely on companies and our government to let us know when there are unsafe levels of gases in the air. Instead, we should take some responsibility as well and have a gas detector in our home to help us stay safe at all times.

You may well wonder 'why do I have so much gas', but realistically you probably passing about the same as everyone else, although it may well feel like more than this. Most people pass wind, either in the form of burping or flatulence via the rectum, about 14 times per day. This equates to between 1 - 3 pints of gas per person. Most of the gas produced in the body has no smell. When flatulence does smell, this is due to small amounts of sulphur being released by certain bacteria in the large intestine.
What are the causes of gas?
Internal gas is caused in 2 ways, either by being swallowed, or by digestive processes in your intestines.
Air that is swallowed will go down into the stomach, it will then be excreted by burping. A small amount enters the small intestine where it is then absorbed into the blood stream and excreted in other ways. If you chew gum, smoke or eat too quickly then this may well be the answer to your question of 'why do I have so much gas.'
There are certain foods which cannot be digested in the small intestine and are passed through to the large intestine. Here it is more likely that these foods will cause gas as the enzymes work to break them down. The type of foods which cause gas are the following:
Soluble fiber Sugars Starches Carbohydrates
Fats and proteins do not cause gas as they break down. When gas is formed in the large intestine, it is passed out of the body as flatulence.
Whilst not everybody is affected by certain foods in the same way, if you eat a lot of these types of foods it can be a reason to 'why do I have so much gas?'
