Fire Hazards

• Fire Hazards 


  Form of threat to fire protection and safety
• Two causes of fire 


  Natural and Man-made
• Natural Causes 


  Result from natural hazards
• What kinds of natual hazards can fire occur from?

  Lightning, heat, and volcanic activity
• Lightning 


  A form and source of heat that can ignite any flammable material
• Volcanic Eruptions


  Fire can be generated by the objects that get burned along the path of lava or by ejected pyroclasic materials.
• Man-made causes 


  Caused by human or machine errors
• Electrical wirings 


  Faulty wirings, short circuits, overloaded circuit, and loose wirng connections may induce fire in any structure or building
• Unattended ignition sources 


  Lighted candle, improvised as lamps, cooking stoves may topple over if left unattended.
• Fire 


  produced from the rapid oxidation of any material resulting in burning.
• Combustion reaction

  Fire can be generated through a chemical process called?
• Fuel+O2-->CO2 + H2O


  Combustion reaction of fire
• Fuel 


  Any materil given favorable conditions reacts quickly with oxygen to produce fire be it light or heat energy. The products of this chemical reaction is Carbon Dioxide and Water Vapor.
• Fuel 


  A fire needs a fuel source or combustibke material in order to burn. Comes in different types and form. Flammability rat depends on the type of material they are composed of.
• Heat 


  Drving force initiating te combustion process
• Petrol


  A liquid fuel that can be ignited at 43oC below 0
• Oxygen


  constitute 21% of air around us reacts with flammable vapors by fuels and the reaction releases heat
• Cigarette 


  its not-proerly put out butts and thrown carelessly can spark a fire
• Chemicals 


  hazardous and flammable substances found at home
• Keep in cool storage 


  some chemicals have a label in it as change in temperature an cause ignition
• Gasoline leaks from vehicles 


  Caused y corroding or destroyed seals or compartments
• Fire and Smoke


  Two critical issues that need imediate attention
• CPR


  Cardiopulmonary Resuscitation
