CSOC Emergency Response on Site 2

Question 1

What type of fire extinguisher should NOT be used in a confined space on a Singapore construction site?

Accepted Answer

Carbon dioxide (CO2) extinguisher, as it displaces oxygen in enclosed spaces creating a suffocation risk

Answer

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?

Accepted Answer

Call 995 immediately, do not enter the excavation (risk of further collapse), mark the victim's location, and wait for trained rescue teams

Answer

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?

Accepted Answer

A life-threatening condition where the body overheats; move the worker to shade, cool them rapidly, call for medical help immediately

Answer

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?

Accepted Answer

A system where workers in hazardous situations always work in pairs so one can raise the alarm if the other is injured

Answer

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?

Accepted Answer

Emergency services numbers (995/999), nearest hospital, site safety officer contacts, poison control, and utility emergency contacts

Answer

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.
