A fire extinguisher is an absolute necessity in any home or office. While there's a good chance that the extinguisher will sit on the wall for years, collecting dust, it could end up saving your property and even your life.

In this article, we'll see exactly what fire extinguishers do and how they do it. We'll also find out what causes fire in the first place, learn the correct way to use an extinguisher and see what sort of fire suppressant works best on different types of fires.

Fire is the result of a chemical combustion reaction, typically a reaction between oxygen in the atmosphere and some sort of fuel(wood or gasoline, for example). Of course, wood and gasoline don't spontaneously catch on fire just because they're surrounded by oxygen. For the combustion reaction to take place, the fuel has to be heated to its ignition temperature.

Fire is the result of a chemical combustion reaction, typically a reaction between oxygen in the atmosphere and some sort of fuel (wood or gasoline, for example). Of course, wood and gasoline don't spontaneously catch on fire just because they're surrounded by oxygen. For the combustion reaction to take place, the fuel has to be heated to its ignition temperature.

Here's the sequence of events in a typical wood fire:

Something heats the wood to very high temperatures. This could be any number of things -- focusedlight, friction, something else that is already burning.
When the wood reaches about 500 degrees Fahrenheit (260 degrees Celsius), the heat decomposes some of the cellulose material that makes up the wood.
Decomposed material is released as volatile gases, typically a compound of hydrogen, carbon and oxygen.
When the gas is hot enough, the compound molecules break apart, and the atoms recombine with the oxygen to form water, carbon dioxide and other products.
The gases, which rise through the air, make up the flame. Carbon atoms rising in the flame emit light as they heat up. (Check out How Light Bulbs Work to find out why heated objects emit light.)
The heat of the flame keeps the fuel at the ignition temperature, so it continues to burn as long as there is fuel and oxygen.

As you can see, there are three essential elements involved in this process:

Extreme heat
Oxygen (or similar gas)
Fuel

Fire extinguishers are designed to remove at least one of these elements so that a fire will die out.^[1]

Uncertainties may happen anywhere and everywhere. Fire extinguishers helps a lot in putting off fire, so better be prepared and store one, especially this time of the year where we experience extremely hot weather. Always remember that extreme heat is one of the elements that causes fire. Be prepared and be safe!

Mosquitoes are one of the transmitters of the deadliest virus called Dengue. No matter how we protect ourselves by wearing long pants, long-sleeved clothes, and the like, this isn't just enough to keep ourselves free from the danger that these mosquitoes carry.

Dengue is an infectious tropical disease that is caused by the dengue virus. Such disease is transmitted by mosquitoes known as Aedes Aegypti which acts as vector in transmitting the virus. Dengue mosquitoes like to stay indoor and near humans. They rest in cool places such as under the tables, bed, furniture, laundry areas, wardrobes, and other places where moist is abundant. They often bite around legs, ankles, and feet. It is indeed difficult to determine whether a mosquito is a carrier of such disease, so we all must take extra care and keep ourselves apart from places where these mosquitoes dominantly stays.

How do we prevent mosquitoes from multiplying?

A lady mosquito lays 100 to 300 eggs at a time and 7 to 10 days is what it takes for an egg to develop to adult. What’s important to remember is that, the larvae that hatched from the eggs survive in stagnant water for them to become adults. If we keep our home clean and organized, or at least get rid of used containers with stagnant water, we are far from acquiring the disease and prevent mosquitoes from multiplying. Usually these mosquitoes spread and bite two hours after sunrise or before sunset. Always remember that they love to stay in cool places, dominantly where moist is present. So, better keep your children away from these places.

How do we combat dengue?

Prevention is better than cure! Keep away from mosquitoes, as much as possible, if traveling to tropical or subtropical places, wear clothes that cover up arms, legs, and neck. And most importantly, to keep yourself worry-free, use the widely recommended OFF! mosquito repellent. Contains 5% DEET and is available in unscented. Proven and tested in protecting families from the diseases carried by mosquitoes and other insects.

It’s always best to keep your self safe and healthy. Keep your family free from mosquito bites, protect them with OFF! Protection that lasts for 24 hours which doesn't leave stain, nor unwanted odour.
