1. Fire Prevention
   • Key Aspects: Training, proper construction, availability of supplies, and ensuring reachability of fire-fighting equipment.
2. Fire Detection
   • Manual Detection: Using pull boxes to manually alert fire services.
   • Automatic Detection: Systems like automatic dial-up that notify the fire department (Auxiliary station alarm).
   • Types of Detectors:
     • Smoke-activated
     • Heat-activated
     • Flame-activated (infrared)
3. Fire Classes and Suppression Methods
   • Class A (Common Combustibles):
     • Extinguishers: Water, Soda Acid.
     • Method: Remove temperature.
   • Class B (Flammable Liquids):
     • Extinguishers: Gas/CO2, Soda Acid.
     • Method: Remove fuel.
   • Class C (Electrical Fires):
     • Extinguishers: Gas/CO2.
     • Method: Displace oxygen.
   • Class D (Metal Fires):
     • Extinguishers: Dry Powder.
     • Method: Specialized agents for metal fires.
4. Fire Suppression Agents
   • Water: Suppresses temperature.
   • Soda Acid: Reduces fuel supply.
   • CO2: Reduces oxygen levels.
   • Halon: Disrupts the chemical reaction in fires.
5. Fire Extinguisher Placement
   • Should be positioned 50 feet from equipment and towards the exit door.
6. Heat Sensitivity
   • Computer Hardware: Sensitive at 175°F (80°C).
   • Magnetic Storage: Sensitive at 100°F (37°C).
   • Paper: Ignites at 350°F (176°C).
7. Sprinkler Systems
   • Wet Pipe: Always filled with water, activated at 165°F.
   • Dry Pipe: Water fills pipes only when activated by heat.
   • Pre-action (Most Recommended): Water is initially held in tanks; pipes fill when air is lost due to heat detection, followed by water release when a thermal link melts.
8. Halon Fire Suppression
   • 1211: Portable Halon units.
   • 1301: Used for flooding areas.
   • FM-200: The most common replacement for Halon (alternatives include CEA, NAF, FE-13, Argon, INERGEN, and Low Pressure Water).
9. Fire Resistance
   • Walls: Rated for 1-hour fire resistance.
   • Adjacent Rooms with Paper: Rated for 2-hour fire resistance.

These concepts are essential for understanding how to prevent, detect, and respond to fire emergencies, particularly in environments with sensitive equipment and materials.
