Question 1

Which fire suppression agent is classified as a clean agent and leaves no residue, making it ideal for protecting sensitive data centre equipment?

Accepted Answer

FM-200 (HFC-227ea)

Answer

FM-200 (HFC-227ea) is a clean agent that suppresses fire without leaving residue, making it safe for electronic equipment.

Question 2

What is the primary purpose of a pre-action fire suppression system in a data centre?

Accepted Answer

To require two separate events before water is released, preventing accidental discharge

Answer

Pre-action systems require two independent triggering events (e.g., smoke detection plus heat detection) before releasing water, preventing accidental discharge onto equipment.

Question 3

Under NFPA 75, what is the maximum allowable fire compartment size for IT equipment rooms protected by automatic sprinklers?

Accepted Answer

52,000 square feet

Answer

NFPA 75 allows IT equipment rooms up to 52,000 square feet when protected by automatic sprinkler systems.

Question 4

A data centre experiences a fire alarm activation. Staff verify it is a real fire in a raised-floor void. Which action should be taken FIRST?

Accepted Answer

Evacuate personnel and activate the suppression system per the emergency plan

Answer

Immediate evacuation and activating suppression per the emergency response plan is the correct first action during a confirmed fire event.

Question 5

What fire detection technology is most effective at detecting slow, smoldering fires in early stages within a data centre?

Accepted Answer

Very Early Smoke Detection Apparatus (VESDA)

Answer

VESDA (Very Early Smoke Detection Apparatus) uses aspirating sampling to detect extremely low concentrations of smoke, identifying smoldering fires long before conventional detectors.
