Fire Hazard

• Fire Hazard - Any actions, materials, or conditions that might increase the size or severity of a fire or that might cause a fire to start are called fire hazards
• FIRE - is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.
• Fuel - any material that can be burned such as solid, liquid, or gas.
• Heat - is an energy that flows through an object.
• Oxygen - is released and serves as an oxidizing agent for combustible materials.
• Oxygen is an element, estimated 21% of it can be found in the air.
• Removing Heat - The goal here is to lower the temperature which is usually accomplished by adding water as an extinguishing agent.
• Removing fuel - is not a practical way of extinguishing fire except when dealing with flammable liquid
• Removing 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 - strikes any combustible material which can set trees on fire
• Lightning - The most common natural cause of fire.
• Volcanic Activities - spews hot gases, ash and lava
• Spontaneous combustion - This happens when a hydrocarbon substance unexpectedly creates fire without apparent cause.
• Pyrophoric substances - ignite spontaneously in air at or below 54 ̊C or within 5 minutes after getting into contact with air
• 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 Chemicals - 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
• Class A -Wood, paper, cloth, trash, and other ordinary materials
• Class C - Live electrical equipment or wirings
• Class B - Gasoline, oil, paint and other flammable liquids
• Class D - Combustible metals and combustible metal alloys
• Class K - Cooking media (vegetable or animal oils and fats)
•  fire drill - a process of practicing how an establishment/building would be evacuated in the event of a fire or other emergencies.
