CSCS Fire Safety and Emergency 4 — Questions and Answers
Question 1: Which type of extinguisher is MOST suitable for a fire involving a computer server room?
- Water
- Foam
- CO2 (Correct answer)
- Dry powder
Correct answer: CO2
CO2 extinguishers are ideal for electrical fires because they leave no residue and do not conduct electricity.
Question 2: What should a construction worker do if their clothing catches fire?
- Run to find water quickly
- Stop, drop, and roll (Correct answer)
- Remove clothing immediately while standing
- Fan the flames to reduce heat
Correct answer: Stop, drop, and roll
Stop, drop to the ground, and roll to smother the flames — running fans the fire and makes burns worse.
Question 3: Fire doors on a construction site should be:
- Propped open for ease of access
- Kept closed at all times unless in use (Correct answer)
- Removed if they obstruct workflow
- Only closed during fire drills
Correct answer: Kept closed at all times unless in use
Fire doors must be kept closed to prevent smoke and fire from spreading between compartments of a building.
Question 4: What is the primary purpose of compartmentalization in building fire safety?
- To improve ventilation
- To contain fire and smoke and slow their spread (Correct answer)
- To provide extra storage space
- To create emergency sleeping areas
Correct answer: To contain fire and smoke and slow their spread
Compartmentalization uses fire-resistant walls, floors, and doors to contain fire and smoke to specific areas, limiting spread and aiding evacuation.
Question 5: Before using a fire extinguisher, a worker should check that:
- The fire is already out
- The escape route behind them is clear (Correct answer)
- Other workers are watching
- The extinguisher is the largest available
Correct answer: The escape route behind them is clear
Always ensure your escape route is clear before attempting to fight a fire so you can retreat safely if the fire grows.
Question 6: On a multi-story construction site, which staircase should workers use during a fire evacuation?
- The nearest elevator
- A designated fire escape stairway (Correct answer)
- The main goods hoist
- Any staircase regardless of smoke conditions
Correct answer: A designated fire escape stairway
Designated fire escape stairways are designed to remain tenable longer; elevators must never be used during a fire evacuation.
Question 7: What action should you take if you discover that a fire exit is blocked by stored materials?
- Work around the obstruction
- Report it immediately to the site manager (Correct answer)
- Move the materials yourself to the nearest storage area
- Only report it at the end of the shift
Correct answer: Report it immediately to the site manager
A blocked fire exit is a serious safety hazard that must be reported immediately so it can be cleared before an emergency arises.
