70% to passWhich fire extinguishing agent can NOT be used on an ethylenediamine?
A
Alcohol foam
B
Dry chemical powder
C
Water foam
D
Water fog
AI Explanation
The correct answer is C) Water foam. Ethylenediamine is a flammable liquid that reacts violently with water. Using water-based extinguishing agents like water foam can cause a dangerous chemical reaction, making the fire much worse. Dry chemical powder (B) and water fog (D) are both appropriate extinguishing agents for ethylenediamine fires, but alcohol foam (A) should not be used as it also contains a water-based component.
