Q

As compared to carbon dioxide, dry chemical has which advantage?

🔍 Key Concepts

• Characteristics of dry chemical extinguishers (how they leave residue, how they discharge, how they affect visibility) • Characteristics of CO₂ extinguishers (how they discharge, range, cleanliness, effect on equipment) • Types of fires each is commonly used on (Class A, B, C, and special metal fires)

💭 Think About

• Think about what happens physically when each type is discharged. Which one comes out under higher pressure and can project farther? • Consider which agent is preferred in spaces with sensitive equipment or electronics and why. • Ask yourself: which agent is more likely to leave residue or cause cleanup issues, and which is considered ‘clean’?

✅ Before You Answer

• Verify which agent is known for being clean and leaving no residue. • Check which agent can create a cloud that travels farther from the nozzle due to the way it is expelled. • Confirm whether standard dry chemical (not special-purpose powders) is actually rated for metal (Class D) fires.
