1. Instruction: Each student will make a concept map discussing the different hazards that may come from Fire. CONNECTING...

2. Questions: What are the three elements of the fire triangle? How does understanding the fire triangle help in fire prevention? What are some typical causes of fire in homes or workplaces? What safety measures can you take to reduce the risk of a fire?

3. Fire Hazards

4. Identify Fire Hazards and related concepts: Fire Triangle, Causes of Fires, and Phases of a fire emergency. OBJECTIVE

5. FIRE HAZARD Fire hazards involve any situation that can lead to uncontrolled fires. These can be natural or human-induced.

6. FIRE TRIANGLE The fire triangle represents the three essential elements for a fire to ignite and sustain: Heat The energy source that raises the temperature of the material to its ignition point. Fuel Any combustible material (e.g., wood, paper, gasoline) that can burn. Oxygen The element that supports combustion. Typically, air contains about 21% oxygen, which is sufficient to sustain a fire.

7. FIRE TRIANGLE Understanding the fire triangle helps in identifying potential fire hazards. Removing or controlling one of these elements can prevent or extinguish a fire. For example, using water to cool the heat, cutting off oxygen by smothering the flames, or removing flammable materials can break the triangle and stop a fire.

8. CAUSES OF FIRES Fires can be caused by various factors, which are generally categorized as: Electrical Faulty wiring, overloaded circuits, or malfunctioning appliances. Chemical Reactions between flammable chemicals or improper storage of combustible materials. Mechanical Friction, overheating of machinery, or improper use of equipment. Human Error Carelessness with open flames, unattended cooking, or improper disposal of smoking materials. Understanding these causes helps in taking preventive measures to reduce the risk of fire incidents.

9. PHASES OF A FIRE EMERGENCY Incipient Phase The beginning stage where the fire is just starting. It can often be controlled quickly if detected early. Growth Phase The fire spreads as it consumes more fuel. It becomes harder to control, and the temperature rises rapidly. Fully Developed Phase The fire reaches its peak, consuming all available fuel. This is the most dangerous stage and requires extensive firefighting efforts. Decay Phase The fire starts to diminish as it runs out of fuel or oxygen. However, it can reignite if conditions change (e.g., new fuel is added).

10. PRACTICAL SKILLS AND KNOWLEDGE Recognizing Fire Hazards Identifying situations where the fire triangle is complete (e.g., presence of flammable materials near a heat source) helps in taking preventive action. Precautionary Measures Practicing safety protocols such as proper storage of flammable materials, routine inspection of electrical systems, and proper housekeeping can significantly reduce fire risks.

11. PRACTICAL SKILLS AND KNOWLEDGE Basic Response Procedures Knowing how to use a fire extinguisher, when to call emergency services, and how to contain small fires can prevent the situation from escalating. Emergency Evacuation Familiarity with evacuation routes, assembly points, and emergency plans ensures that individuals can evacuate safely and efficiently during a fire incident.

12. INSTRUCTION: Write a short essay (150-200 words) explaining the importance of understanding the fire triangle and recognizing fire hazards. Include examples of common fire hazards in everyday settings and suggest two precautionary measures that can help prevent fires. ACTIVITY

13. INSTRUCTION: Read carefully the questions and write your answer in the quiz part of your big notebook.
