Question 393 Deck General

The correct answer is D) All of the above. Triethylene glycol is a combustible liquid, and fires involving it can be extinguished using carbon dioxide, dry chemical, or alcohol foam fire extinguishers. All three of these extinguishing agents are effective against triethylene glycol fires. Carbon dioxide and dry chemical extinguishers work by interrupting the chemical reaction of the fire, while alcohol foam extinguishers create a blanket that separates the fuel from the oxygen. Any of these three methods can be used to safely extinguish a triethylene glycol fire.
