Study Notes
Common Causes of Fire
- Electrical appliances can catch fire if improperly handled or used, or when used while malfunctioning
- Cigarette butts can be dangerous when thrown over areas with large amounts of flammable materials
- Neglected candles or gas lamps can cause fires when left near combustible materials
- Improper use of matchsticks or lighters, especially by children, can accidentally cause fire disasters
- Chemicals can be highly flammable if not stored and handled properly, leading to fires
- Pyrotechnic-related fires can be caused by improper handling and storage of fireworks
- Malfunctioning fireworks can also cause unwanted fires
- Lightning can cause fires when it hits a flammable object on the surface of the Earth
Fire Classification
- Class A: ordinary combustible materials that leave ash, such as paper, wood, plastic, rubber, cloth, and trash
- Class B: combustible chemicals of liquid and gas, such as petroleum oil, gasoline, paint, propane, and butane
- Class C: energized electrical compounds, such as electrical appliances, motor equipment, and machines
- Class D: combustible metals, such as potassium, sodium, aluminum, magnesium, and titanium
- Class K: combustible household liquids, such as cooking oil, animal fat, and grease
Precautionary Measures and Response
- Fire risk assessment is a means to understand the situation of an area and determine the different preventive measures needed to reduce the vulnerability of an area against fire
- Installing a fire alarm system can help in being aware of a fire before it gets big and uncontrollable
- Buying a fire extinguisher and a fire blanket is important in preventing a fire outbreak from becoming uncontrollable
Fire Fuels
- Not all materials can become fuel for a fire
- Solid fuels have definite size and shape, such as wood, paper, leather, grain, cork, coal, cloth, and plastic
- Liquid fuels generate flammable and combustible vapors through vaporization, such as gasoline, kerosene, turpentine, lacquer-paint, varnish-alcohol, and olive oil
- Gas fuels are the most dangerous of all fuel types, requiring less energy for ignition, such as acetylene, hydrogen, propane, carbon monoxide, and methane
