What is fire, causes and Prevention?
This a very vauge question but, Since it ends with Prevention, I will presume to answer it in reference to incedental or an unplanned fire.
Fire:
Fire is the product from a chemical reaction between oxygen in the atmosphere and some sort of fuel (wood or gasoline, for example).
"The combustion or burning, in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke."
Causes:

#1 cause of accidental fires- Cooking equipment (also the number one cause of deaths and injuries)
#2 cause of accidental fires- Heating equipment
#3 cause of accidental fires- Electrical distribution systems
#4 cause of accidental fires- Intentional
#5 cause of accidental fires- Smoking

How to Reduce Your Risk:
•Always stay in the kitchen or by the grill when you're cooking. Never leaving cooking food unattended is the single best way to prevent fires, especially if you're frying, boiling, or broiling.
•If you have to leave the room, turn off the burner.
•Keep flammable materials like towels, curtains, oven mitts, wooden utensils, and food packaging away from the cooking areas.
•Keep a metal lid handy to smother grease fires - never put water on a grease fire, it will explode!
•Get out of the house as fast as you can if there is a fire - then call 911. More than half of non-fatal cooking fire injuries occur when homeowners try to put out the fire on their own.
•Keep your fire alarm on while you're cooking - never disable it. Make sure you have a fire extinguisher in your kitchen.
Heating Equipment:

How to Reduce Your Risk:
•If you must use a space heater, keep it at least three feet away from anything flammable, including bedding, mattresses, clothing, and upholstered furniture - that's the biggest factor in heating fire deaths. •Make sure children stay at least three feet away from space heaters and open fires.
•Turn portable heaters off when you leave the room or go to sleep. Don't keep them on all night.
•Always use a screen in front of your fireplace, and have your chimney professionally cleaned annually. Douse any fire or coals at night before you go to sleep or if you leave the house.
•Never heat your home with your oven.
Electrical Systems:

How to Reduce Your Risk:
•Always hire licensed electrical professionals to do electrical work in your home. Don't do the work yourself.
•Plug major appliances like refrigerators, washers, and dryers directly into wall outlets instead of using extension cords or power strips.
•All outdoor, bathroom, kitchen, garage, and basement outlets should be protected with ground fault circuit interrupters (GFCIs), which cut off electrical circuits when they become shock hazards.
•Don't overload outlets, especially with heat-producing appliances like toasters and space heaters. Plug only one of those into an outlet at a time. •Never exceed the maximum wattage on light fixtures.
•Call an electrician right away if you notice potential electrical problems, like frequent blown fuses, discolored, warm, or sparking outlets, or burning smells coming from appliances.
Sorry I answer your question by a question: Does fire exist without oxygen?
What is fire?
A tool that can help us (e.g. cooking, sanitizing, lighting, warming up etc.) or harm others (e.g. attacking, killing, burning down property etc.)
Causes?
Depending on what outcome we want to achieve from fire.
Prevention?
Depending on our human motive or objective.

Apart from the destructive nature of fire, it's also help to break seed dormancy
Fire is a process in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke; combustion or burning. earlier it was Triangle, but now Tetrahedron.
earlier fuel, heat, and oxygen added with chemical chain reaction.
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Fire is hot because the conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.
Causes
For a fire to start it needs a source of ignition, a source of fuel and a source of oxygen. For example, if a smoker falls asleep with a cigarette still lit, and sets fire to the sofa, the cigarette is the source of ignition, the material on the sofa is the source of fuel and the air is the source of oxygen.
