Question 743 Deck General

The correct answer is D) CO2. According to the Chemical Data Guide for Hazardous Materials, carbon dioxide (CO2) is the recommended extinguishing agent for an ethyl chloride fire. Ethyl chloride is a flammable gas, and CO2 is an effective extinguishing agent that can displace oxygen and smother the fire. The other options, such as carbon tetrachloride, alcohol foam, and water foam, are not recommended for an ethyl chloride fire as they may not be as effective or could potentially react with the fuel source.
