fire

• Fire is the rapid oxidation of a material in the exothermal chemical process of combustion, releasing heat, light, and various reaction products.
• Fuel is any material that can be burned such as solid, liquid, or gas.
• Combustion takes place when fuel is converted into gaseous state as moisture is removed. 
• Heat is an energy that flows through object.
• flash point The lowest temperature needed to form an ignitable mixture in air near the surface of the liquid is called the 
• Oxygen is released and serves as an oxidizing agent for combustible materials. 
• REMOVING THE HEAT. The goal here is to lower the temperature which is usually accomplished by adding water as an extinguishing agent. 
• removing the fuel from the fire is not a practical way of extinguishing fire except when dealing with flammable liquid fires, valves can be shut off and storage vessels pumped to safe areas to help eliminate the supply of fuel to the fire.
• REMOVE THE OXYGEN Removal of the air or oxygen can be accomplished by separating it from the fuel source or by displacing it with other gases like carbon dioxide, nitrogen and steam.
• Lightning that strikes any combustible material which can set trees on fire that might eventually result to forest fire or wildfire. This is the most common natural cause of fire.
• Volcanic activities During volcanic activity, it spews hot gases, ash and lava and when these hot materials get in contact with flammable materials it might start a wildfire.
• Spontaneous combustion this happens when a hydrocarbon substance unexpectedly creates fire without apparent cause. 
• Cooking equipment. Pots and pans can be overheated when a person gets distracted while cooking or leaves cooking unattended. This is the most common cause of housefire.
• Heaters. Portable heaters can cause fire when it is placed near objects that can easily burn like curtains and laundry clothes.
• Smoking in bedrooms. A cigarette that is not put out properly can cause fire as the cigarette butts can continuously burn in a few hours. 
• Candles. It is not actually a hazard but when left unattended it can easily burst into flames and cause fire.
• Curious children. Kids can sometimes cause fire out of curiosity, so they wanted to see what would happen if they set fire to an object.
• Faulty wiring. Homes with insufficient wiring can cause fires from electrical hazard. 
• Barbeques. This is a great outdoor activity or one of the famous street foods in the Philippines. Avoid doing this activity near tablecloths, trees or even plants.
• Flammable liquids. Petrol, kerosene or other methylated substances are the most common flammable liquids found at home that can cause fire if not properly stored. Always store in cool, dry place.
• Lighting. Lamp shades and light fittings can build heat if they are very close to light bulbs. 
• Cooking is the #1 cause of home fires, and unattended cooking is the top contributing factor 
• Cigarettes are the leading causes of fire deaths in city, state, and national level
• Electrical problem is one of the causes of structure fires and fire deaths. 
• Candle Safety During brown out or power outage, candles are the most popular source of light because it is always available even in sari-sari stores.
• Spontaneous combustion happens when a material can produce or accumulate its own heat and can cause increase in temperature without drawing heat from its surroundings. 
• Water and Foam – only used to put out class A fires
• Carbon Dioxide – can be used to put out class B and C fires
• Dry Chemical – can be used to put out class A, B and C fires
• Wet Chemical – can be used to put out class A and K fires
• Clean Agent – also known as halogenated extinguishers, can be used to put out class A, B and C fires
• Dry Powder – only used to put out class D fires
• Water Mist - can be used to put out class A and C fires
• Fire safety signs are color coded for easier identification and determination which is mandatory and which should be avoided. 
• Fire exit signs are colored green and white as this color combination means a safe condition. 
• Blue fire safety signs are used to indicate a mandatory action or a must do action. 
• Red fire safety signs are used to indicate prohibition or you must not go on that location because it might pose danger or harm. 
• Electricity – neglect or misuse of wiring can lead to short circuits
• Rubbish and waste material – fire is likely to spread through accumulated waste
• Smoking – carelessly discarded cigarette butts or lit matches are one of the major causes of fire
