CSOC Emergency Response on Site 2 — Questions and Answers
Question 1: What type of fire extinguisher should NOT be used in a confined space on a Singapore construction site?
- Dry chemical powder
- Carbon dioxide (CO2) extinguisher, as it displaces oxygen in enclosed spaces creating a suffocation risk (Correct answer)
- Water extinguisher
- Foam extinguisher
Correct answer: Carbon dioxide (CO2) extinguisher, as it displaces oxygen in enclosed spaces creating a suffocation risk
CO2 extinguishers displace oxygen to smother fires. In confined spaces, this oxygen displacement creates a serious suffocation risk for anyone inside the space.
Question 2: What should be done if a worker is trapped in a collapsed excavation on a Singapore construction site?
- Dig them out immediately with an excavator
- Call 995 immediately, do not enter the excavation (risk of further collapse), mark the victim's location, and wait for trained rescue teams (Correct answer)
- Wait until the next shift to assess
- Use water to wash away the soil
Correct answer: Call 995 immediately, do not enter the excavation (risk of further collapse), mark the victim's location, and wait for trained rescue teams
Untrained rescue attempts in collapsed excavations often result in additional casualties. Call SCDF (995) immediately, keep others away from the unstable area, and let trained rescue teams handle the extraction.
Question 3: What is heat stroke and how should it be managed on Singapore construction sites?
- A minor headache from sun exposure
- A life-threatening condition where the body overheats; move the worker to shade, cool them rapidly, call for medical help immediately (Correct answer)
- A type of sunburn
- A muscle cramp from dehydration
Correct answer: A life-threatening condition where the body overheats; move the worker to shade, cool them rapidly, call for medical help immediately
Heat stroke is a medical emergency common in Singapore's tropical climate. The body temperature rises above 40°C. Immediate cooling (remove excess clothing, apply cold water, fan) and emergency medical attention are critical.
Question 4: What is the 'buddy system' recommended for hazardous work on Singapore construction sites?
- A social programme for new workers
- A system where workers in hazardous situations always work in pairs so one can raise the alarm if the other is injured (Correct answer)
- A training partnership programme
- A carpool arrangement for workers
Correct answer: A system where workers in hazardous situations always work in pairs so one can raise the alarm if the other is injured
The buddy system ensures that workers performing hazardous tasks (confined space entry, work at heights, electrical work) always have a colleague nearby who can raise the alarm and initiate rescue if something goes wrong.
Question 5: What information should be included in a Singapore construction site's emergency contact board?
- Only the site manager's name
- Emergency services numbers (995/999), nearest hospital, site safety officer contacts, poison control, and utility emergency contacts (Correct answer)
- Only the company head office number
- Only the ambulance number
Correct answer: Emergency services numbers (995/999), nearest hospital, site safety officer contacts, poison control, and utility emergency contacts
The emergency contact board should display all relevant emergency numbers including SCDF (995), Police (999), nearest hospital/clinic, site safety officer, company emergency contacts, and utility companies.
Question 6: What actions must the site supervisor take after a workplace accident on a Singapore construction site?
- Only file an insurance claim
- Provide first aid, secure the scene, report to MOM as required, investigate the root cause, and implement corrective actions (Correct answer)
- Only clean up the area
- Only inform the worker's family
Correct answer: Provide first aid, secure the scene, report to MOM as required, investigate the root cause, and implement corrective actions
After an accident, the priority sequence is: provide immediate medical assistance, secure the accident scene (for investigation), report to MOM within the required timeframe, investigate root causes, and implement measures to prevent recurrence.
