Chemists in the 1700′s began using fire extinguishers using a basic form of chemistry. They understood the need for safety and the probability of accidents. That’s why these revolutionary devices were slowly improved upon, developing into a diverse collection of fire extinguishers divided by fire extinguisher class. These different classes are devised to ensure that no matter what type of fire you may experience, you have an extinguisher that can safely and properly put a fire out. Why are different classes so important? Because they tell you the types of fires your extinguisher can be used on, and they tell you how effective it will be on those particular fires.
There are some basic fire extinguishers that are great for every day usage. The Class A or Class B extinguishers are meant to put out some dangerous, but general fires. Class A is all about extinguishing organic materials. This includes organic matter such as paper, wood, or even to put out a flaming garbage can or campfire. Class B, on the other hand, is formulated to help put out fires caused by or including gasoline, oil, kerosene, lighter fluid, or other flammable liquids. If you own a workshop or are trying to get extinguishers for your garage, these may both be a great choice.
Some fire extinguishers are not to be used in everyday fires that are caused by paper, wood, or gas. For example, the Class D fire extinguisher is used to combat flammable chemicals like magnesium or zinc. In laboratories, this can be of particular use, as accidents can sometimes be frequent if the workers are not careful. There are also extinguishers designed to put out fires next to electrical sources. They are known as Class C extinguishers in the US (there is no separate class for these in the UK). These extinguishers are extremely important in high risk jobs, where electrical exposure may be common.
A regular extinguisher would only agitate the situation more, as the Class C extinguisher is the only one that does not conduct electricity at all. Using another extinguisher would do way more harm than good, and the same is true for the Class D extinguisher. These are meant to be used in specific and dangerous circumstances.
If you are dealing with flammable gases you will want to acquire an Extinguisher in class C (in the UK) or class B in the US. These are a smart decision for those who intend to work in a lab as well. There are many different chemical reactions in a lab that must be dealt with in entirely different ways. On a completely different level, there are some establishments that may need a Class F extinguisher to deal with fires that are a result of cooking oils or fats. This gets dangerous in restaurants that fry foods or have large barbecue pits. These are known as class K in the US.
Finding the right extinguisher in the UK can be easy if you know which class will best suit your needs. Fire extinguisher class is very important to pay attention to. In addition to providing you with different classes to choose from, the fire extinguishers provide you with different numeric values that indicate the size of fire the appliance can deal with (the larger the number the larger the fire). If in doubt make sure you check with your local fire authority or an experienced consultant.

A sore throat is an acute inflammation of the lower pharynx. This inflammation usually affects the mucous membrane and causes it to discharge secretions similar to sputum. In some cases, the throat can be very dry that coughing to discharge the secretions can be harsh on the throat. The tonsils and the soft palate may also become inflamed and cause pain when swallowing. A burning sensation and a tightness in the throat are also common occurrences when one has sore throat.
Some common causes of sore throat include colds, allergies, and habits like breathing through the mouth. A sore throat can also be an indication of a more serious disease if it is severe and chronic. However, for mild and random sore throats, the following sore throat relief ideas work effectively:
Consider the cause of your sore throat.
Determining the cause of your sore throat is necessary before you can administer the proper cure and relief treatment. If colds and flus are prevalent in your office or any place you frequent, these viruses are probably the cause of your sore throat. Excessive shouting and eating foods that are too spicy can also cause sore throats. However, if you suspect that your sore throat is caused by something more serious like strep throat, you must have it checked by your doctor.
Take prescription or over-the-counter painkillers.
Your doctor can prescribe prescription medication for your sore throat. Depending on the severity or the perceived cause, he or she can prescribe plain painkillers or one with antibacterial properties. You can also use over-the-counter painkillers like ibuprofen or naproxen to relieve the pain in your throat. You can also take an analgesic to reduce inflammation like aspirin and acetaminophen. Just be sure to inform your doctor of any medication you have taken or are currently taking. This way, you can avoid over-medicating and possibly adverse drug interactions.
Suck on throat lozenges.
Lozenges with zinc, menthol, benzocaine, or phenol are ideal to suck on since they can numb the throat. Menthol hard candies are also good substitutes if you cannot find lozenges. Sucking on lozenges promote saliva production which prevents dryness and scratching in the throat. Saliva production also reduces the chances of bacterial infections in the throat.
Gargle mouthwash or salt water frequently.
The alcohol in the mouthwash has antiseptic properties which can cleanse the throat if there are bacteria. It also disinfects scratches and lesions in the throat which might be caused by dry coughing. Salt water works the same way and is cheaper in comparison. Simply combine a teaspoon of salt in eight ounces of warm water. Gargle the mixture several times a day. This will increase the blood supply to the area by washing away mucus and dilating capillaries, thereby enabling better circulation of infection-fighting antibodies.
Eat a soft or liquid diet.
Instead of meals that require you to swallow solid food like meat, opt for soups, yogurts, and mashed vegetables to avoid irritating your throat further. Supplement this diet with lots of water and natural fruit juices to facilitate the development of antibodies. Remember to avoid too much spices in your meals as these can aggravate your sore throat.
