Fire Hazard

• Fire has been used by early humans for survival. Important tools in building both ancient and modern civilizations
• Fire can also influences the type of population of flora and fauna
• Fire Tetrahedron is a triangular pyramid. A visual aid that reminds us of the four important ingredients to initiate and sustain fire namely: Heat, Fuel, Oxidizing agent, Uninhibited chemical reaction
• Heat is an energy that flows from an object of high temperature to an object of low temperature and can be produce in many ways both by man and nature
• Fuel are any solid, liquid or gaseous substance that can be burned.
• Pyrolysis is a chemical decomposition of solid fuels which produces gas fuel through application of heat
• Oxidizing Agent is an element or a compound which releases oxygen or other oxidizers during a chemical reaction
• Other oxidizing agents: Bromates, Bromine, Chlorates, Chlorine, Flourine, Iodine, Nitrates, Nitric acid, Nitrites, Perchlorates, Peroxides, and Permanganates
• Uninhibited Chemical Chain Reaction are combustion or burning-an exothermic reaction becomes selfsustained because the heat given off during combustion is used again to heat the fuel and maintain the burning
• Wildfires is any natural or anthropogeniccaused uncontrolled fire in remote areas where the is extensive combustible vegetation or organic material like forest grasslands, shrublands, brushlands, scrublands, and peatlands
• Types of Wildfires: Ground Fires, Surface Fires, Crown Fires, and Ladder Fuels
• Causes of Wild Fire: Natural and Human Activities
• Different Types of Fire: Class A, Class B, Class C, Class D, Class K
• Class A are fires involved fuels such as cloth, wood, paper, plastics, rubber, and trash
• Class B are fires involve combustible liquid such as fuel, alcohol, gasoline, lacquers, oil, base paint, petroleum oil
• Class C are fires involve fuel that belongs to either class A or B but also involve powered electrical equipment like home appliance, motors and transformers.
• Class D are fires involve combustible metals such as aluminum, lithium, magnesium, potassium, sodium, titanium, zirconium
• Class K are fires involve fuels such as cooking oil and grease
• Choosing Fire Extinguishers: Water Foam, Carbon Dioxide, Dry Chemicals, Wet Chemical, Clean Agent, Dry Powder, and Water Mist
• Fire Emergency Response: Rescue people from immediate area of the smoke, Alarm activate the nearest fire alarm pull station, Contain the smoke or fire by closing all windows and doors, Extinguish the fire by using the appropriate fire extinguisher
• Fire Extinguisher: Twist, Pull the pin breaking the plastic seal, Aim at the base of the fire, Squeeze the handles together, Sweep from side to side
