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

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?'
Home security is a growing concern for millions of people. Even though the housing market is in the tank, the average value of a home these days is still 0,000. Not exactly chicken feed! It is still the largest investment most families will ever have. Yet more people have their cars alarmed than have their homes protected. Part of the reason for that is because of cost concerns.
And it is true that you can spend a ton of money on all kinds of home security systems and devices. Here's a review of four of the best motion detector alarms that are meant to improve your home security and provide some level of home invasion prevention and home burglary prevention.
With one out of six homes annually the victim of home burglary, home burglary prevention and home invasion prevention are uppermost on the minds of homeowners not only to improve their home security but to protect their family and their personal possessions.
1. The HomeSafe home security system. It includes: one base unit with programmable keypad and 105 dB alarm siren; one window and door sensor that's wireless with a range up to 300 feet; a wireless motion sensor with the range up to 25 feet; and one key chain remote that can be used to arm and disarm the unit and a panic button. If motion is detected when the unit is armed. It will call up to five preset phone numbers with a prerecorded message. The system can be used for invalid elderly people who live alone as a caretaker emergency notification system.
2. The Voice Alert System. This system includes a base unit and up to six wireless sensor transmitters that can transmit up to 1000 feet in open space and 300 feet through walls. Each area is protected by a sensor and each zone has its own prerecorded message to alert you when activity is in the area. The annunciator system not only protects areas but can activate up to four relays to operate equipment like outdoor floodlights. This system can be used for commercial applications as well.
3. The Laser Sensor Alarm includes a transmitter and receiver that transmits an invisible IR light between them that can extend to 60 feet long. When that beam is penetrated a loud alarm or pleasant chime sounds. The volume on the chime can be set to low, medium or high and is a perfect application for a retail store to announce customers.
4. The "Electronic Watchdog" is a wireless system that uses PIR technology. When somebody enters the protected area up to 20 feet away the sound of an angry barking dog starts. A remote control unit allows you to arm and disarm the watchdog. The barking dog alarm can also be used for commercial purposes to protect warehouses offices and fenced in areas.
These are four of the best motion detector alarms for your home security.

There are plenty of more reasons why the Safety Siren Pro Series 3 Radon Gas Detector is the best available but I am sure you already get the picture.
Why should I be concerned about radon levels for me and my family?
The simple fact is exposure to high levels of radon has been linked to the development of lung cancer. This isn't just a problem for the elderly either. Lung cancer due to exposure can even affect children. Certain areas of the country are prone to higher concentrations and it is essential for every home to have continuous radon detection. There are several one time detection kits on the market but this is simply not good enough. Danger levels vary depending on the amount of humidity and season, thus leaving a person exposed without continuous monitoring. The safety of one's family is of utmost importance when it comes to purchasing a model that offers continuous protection.

You are working very hard to give your family a good life. Nice cars, state-of-the art equipments like home theater systems, personal computer, cellular phones, jewelries and other expensive items are inside your home. As you leave your house every day, are you not worried that these things might be stolen and you might lose everything you have worked so hard for? If so, a home alarm system could help you protect your home from burglaries. You see break-ins occurring every 4 minutes normally during the day, when homeowners are least likely to be home. Most often than not, unprotected homes are always the target. Leaving a dog in the house and a well locked home with a siren could scare small time burglars from intruding your home.
However, there are professionals out there that carefully plan how to get into your home the moment you leave your house. Professional thieves plan beforehand how and when they would break into your home. For months, they would monitor your activities. They observe at a distance your habits, what time of day people come and go, when you pick up your mails, or whether you try to deceive thieves by having lights that automatically turns on and off while you are out.
Usually, thieves break into homes that have no home alarm system. There are so many houses that are still left unprotected. According to convicted thieves, they avoid houses which they know have installed alarm systems. You need a good home alarm system to safeguard your home.
Wireless home alarm system with 24/7 monitoring is an excellent choice. This alarm system is very easy to install. You could do it by yourself or with the help of a professional. It comes as a complete kit or you could buy the base unit and purchase other extras as needed. It is one of the most dependable among those available in the market. It may have a pet immune motion sensor, an important feature which enables your pets to move safely without setting off the sensors. It also has a latchkey feature that allows you to check, remotely, whether your children have gone home at the specified time.
If break-in happens, the system can dial up to three different phone numbers. It can actually talk to you with a synthesized voice and explain the problem. It could also be programmed to call your security monitoring company. It also gives you other secondary benefits like fire and smoke detection or the presence of poisonous carbon monoxide gas. Wireless home alarm system could also be linked to a remote personal computer that enables you to see your home when you are away. You can also insure your home at 20% less of regular insurance coverage. Some insurance companies offer as much as 20% discount for homes with security system, just scout for them.
With the wireless home alarm system, you could spare your home from possible break-ins. However, you still have to do your part of locking your doors and closing the windows when you leave. Such double protection could afford you the luxury of being away from home without the fear of losing all your valuables.

Where to install a smoke detector and its positioning are as important as having this life saving device installed at all. Placing a smoke detector in a wrong location might delay its response to smoke or even prevent it from sounding an alarm at all.
Although, you should install smoke alarms by following device manufacturers guidelines, and the NFPA standards (National Fire Protection Association), your local jurisdiction might have a different idea. This idea is usually LESS smoke detectors - Chicago is one of the examples.
Since it is your life we are talking about, following just a minimum requirement is not enough - for literally a few dollars more, you can get maximum protection.
Proper Placement of a smoke alarm based on IRC (International Residential Code), IBC (International Building Code) and NFPA:
New construction:
Smoke detectors must be hard wired (power supply from the electrical panel) and require battery backup. Your jurisdiction might require a dedicated circuit for this purpose - if such isn't required, make sure that you smoke detector hasn't been installed on a circuit / tapped to the wall switch controlled ceiling light fixture or outlet receptacle. Putting a smoke alarm on a GFCI protected electrical circuit also isn't a good idea. Do not use rechargeable type batteries for smoke detectors, good quality alkaline type battery is the right choice. Smoke alarms shall emit a signal when the batteries are low - replace the battery with a new one as soon as you hear that repeating sound. Smoke detectors are required in each sleeping area and adjoining bedroom. Like I've mentioned before, some jurisdictions require less - Chicago is one of the examples where smoke detectors are not required inside the bedroom / sleeping area. Instead, you have to install a smoke alarm within 15' from the bedroom entrance. In larger homes / apartments, where bedrooms are located more than 30' apart, two or more smoke detectors might have to be installed. At least one is required on each story of the house and in the basement. Crawlspaces and uninhabitable attics do not require a smoke detector installation. However, in case your attic or crawlspace contains a furnace, water heater, or any appliance that could become a source of fire (gas, oil, electric), have a smoke alarm installed as well (required by some jurisdictions and highly recommended if not required). Smoke detectors must be interconnected - one triggered smoke detector activates all of them. Not all types of smoke alarms have the "interconnection" feature, which is extremely important - smoke developing in one section of the house would activate the closest device and automatically all of them at the same time.
Existing construction:
While remodeling, hard wiring and interconnection of smoke detectors is not required if finishes would have to be removed. However, you can still achieve maximum protection by using an interconnected wireless smoke alarm system.
The smoke alarm shall be clearly audible in all bedrooms over the background noise levels with all intervening doors closed. That's why regular testing of the smoke detector siren is so important - just like any mechanical / electronic device - sometimes they fail. Enclosed interior staircases also require a smoke detector, and one shall be installed on the ceiling of the top floor. Staircases act like chimneys and smoke rising from the lower floor would activate the device giving you an early warning.
Smoke detector placement - rules apply to all of the locations described above.
This is extremely important and at the same time quite simple, unfortunately very often done completely wrong. It's probably because we don't like to read the manuals and often assume that we know what we're doing.
When installing a smoke alarm on the ceiling (preferable location / might be required in some jurisdictions), place it as close to the center as possible, never closer than 4" (10cm) to the sidewall or corner. If for any reason, ceiling installation is not practical and wall installations are permitted, you can install smoke alarms on the wall with its top edge at a minimum of 4" (10cm) and a maximum of 12" (30.5cm) below the ceiling.
Before placing a smoke detector on the ceiling or wall, consider checking the house insulation. Older homes might be missing a ceiling (if open to the attic) or exterior wall insulation. This would allow extreme heat or cold transfer from exterior into the house, creating a thermal barrier, and prevent smoke from reaching / activating the alarm. If this is the case (you can simply touch the wall or ceiling during very hot or cold days), mount a smoke detector on an interior wall of the house.
Install smoke detectors in rooms with cathedral, sloped, peaked, gable ceilings at or within 3' from the highest point (measured horizontally). Install smoke detectors in each section of the room / area that has been divided by a partial wall. The wall might be coming down from the ceiling (at least 24") or up from the floor. Install smoke alarms on a tray-shaped ceiling (also called coffered ceiling) on the highest portion of the ceiling or on the sloped portion of the ceiling within 12" (30.5cm) vertically down from the highest point.
DO NOT install smoke detectors in following areas to minimize possibility of false alarms:
Areas where combustion particles are present (Combustion Particles - the by-products of burning process) garages poorly ventilated kitchens close to furnaces and water heaters - I wouldn't agree with this one, because presence of those particles would be a sign of combustion process problems If you decided to have one installed in those areas, photoelectric type smoke alarm might be less annoying. Damp or very humid areas such as bathrooms. The humidity levels after taking a hot shower could result in a false alarm. Within 3' from the forced air heating and / or cooling system air supply vents, in a direct airflow area, close to the whole house fan locations. High air flow could blow smoke or shift it away from the detector preventing it from responding properly or at all. Near fluorescent lights, where electronic "noise" may cause nuisance alarms. Dusty areas, where particles of dust could cause smoke alarm failure or false alarm In areas where air temperature may fall below 40°F (4°C) or rise above 100°F (38°C) Avoid areas near the doors and windows while installing a smoke alarm
If you got that far, I hope you have more than a general idea on where to install smoke detectors in your house, and what is the optimal smoke alarm placement.
