Safety, Fire & Survival · Fire — Clean Agent Systems
Gaseous clean-agent total-flooding systems (e.g., FM-200/HFC-227ea, Novec 1230) are used in machinery and electronic spaces because they:
- AIncrease the oxygen level
- BAdd large amounts of water
- CAre corrosive to electronics
- DExtinguish without leaving residue or conducting electricity, and are safer for occupied spaces than CO2 at design concentration✓ Correct
Explanation
Clean agents suppress fire (mainly by heat absorption, some by chain-reaction inhibition) and leave no residue, do not conduct electricity, and at design concentration are less hazardous to personnel than CO2 — making them suitable for electronic and some normally occupied spaces.
