Study Notes
Fire Hazards
- Fire hazards include live flames, sparks, hot objects, and chemicals that can ignite or aggravate a fire, as well as potential threats to fire prevention, firefighting, and built-in fire safety systems.
- Fire hazards pose threats to life and property, and the primary object of safety systems is to detect, remove, or reduce these risks.
Elements of the Fire Triangle
- The fire triangle is a model that represents the three interdependent elements needed for fire: heat, fuel, and oxygen.
- Heat is necessary for the initial ignition of fire and its spread, and can be caused by various sources such as candles, stoves, and electrical appliances.
- Fuel is any combustible material, and its characteristics (moisture content, size, shape, quantity, and arrangement) affect its ability to burn.
- Oxygen is necessary for combustion to occur, and most fires require at least 16% oxygen content to burn.
Top Causes of Fire
- Cooking equipment is the leading cause of home structure fires and injuries.
- Smoking is the leading cause of civilian home fire deaths.
- Other common causes of fire include faulty wiring, kitchen stoves, smoking in bed, lighting, flammable liquids, candles, and children playing with fire.
Precautionary Measures
- Before a fire incident: have a disaster plan, ensure smoke alarms are installed and functional, keep household fire extinguishers handy, and make sure you can open windows, screens, security bars, and doors.
- During a fire incident: get to the nearest exit immediately, contact emergency services, and do not go back into a burning building.
- After a fire incident: wait for the fire department's instruction before re-entering your home, contact relevant agencies, collect valuable materials, and assess the damage.
NCCC Mall Fire Incident
- The NCCC Mall Fire incident on December 23, 2017, had a main cause and resulted in casualties (research required to identify the exact cause and casualties).
