Quiz on 4 Stages of Fire

What actions should be taken during the incipient stage of fire?

• Close all windows and doors to contain the fire

• Run around in panic without a plan

• Activate fire alarm, notify others, attempt to extinguish if safe, evacuate if necessary

• Ignore the fire and continue working

What is the primary characteristic of the growth stage of fire?

• Rapid increase in size and intensity

• Sudden decrease in size and intensity

• Slow increase in size and intensity

• No change in size and intensity

What are the key factors that contribute to the growth stage of fire?

• Metal, wood, and plastic

• Light, sound, and heat

• Water, wind, and fuel

• Fuel, oxygen, and heat

How does the fire behavior change during the growth stage?

• No change in fire behavior

• Slow and controlled spread of flames

• Decrease in temperature and flame intensity

• Intense and rapid spread of flames

What are the main features of the fully developed stage of fire?

• Moderate spread of flames, moderate heat, and potential for structural stability.

• No flames, minimal heat, and no potential for structural collapse.

• Rapid spread of flames, intense heat, and potential for structural collapse.

• Slow spread of flames, mild heat, and no potential for structural collapse.

What are the potential hazards during the fully developed stage of fire?

• Plants, animals, rocks, water

• Light, sound, color, smell

• Heat, smoke, toxic gases, structural collapse

• Water, wind, sand, foam

How does the fire spread during the fully developed stage?

• Rapidly and intensely, consuming all available fuel and oxygen.

• Intermittently and weakly, struggling to sustain the fire

• Erratically and unpredictably, causing uneven consumption of fuel and oxygen

• Slowly and steadily, conserving fuel and oxygen

What are the signs of the decay stage of fire?

• Increase in heat and flame, absence of smoldering materials, no smoke

• Rapid spread of fire, presence of water, strong wind

• Decrease in heat and flame, presence of smoldering materials, heavy smoke

• Brighter flames, absence of smoke, increase in temperature

What are the challenges faced by firefighters during the decay stage of fire?

• Decreased risk of injury

• Structural instability, collapse hazards, and potential re-ignition

• Lack of water supply

• Minimal smoke and heat

What are the key elements of fire control during the incipient stage?

• Using gasoline to try to control the fire

• Ignoring the fire and hoping it will go out on its own

• Using a fire extinguisher, applying water or other extinguishing agents, and ensuring proper ventilation

• Closing all windows and doors to prevent the fire from spreading
