🔍 Key Concepts

• Typical storage pressure range for portable CO₂ extinguishers at room temperature • Difference between stored-pressure extinguishers and cartridge-operated or liquefied-gas extinguishers • Relationship between CO₂ as a liquefied gas and its vapor pressure at about 70°F (21°C)

💭 Think About

• Think about whether CO₂ in an extinguisher is mostly a liquid, a gas, or a mix at room temperature, and how that affects pressure. • Compare the answer choices to what you might expect for a cylinder that must stay compact but discharge forcefully—does it need low, medium, or quite high pressure? • Recall approximate vapor pressure values for CO₂ at normal room temperature and match the closest option.

✅ Before You Answer

• Be sure you know that CO₂ extinguishers contain liquefied CO₂ under pressure, not just compressed air. • Check which of the listed pressures is in the typical vapor pressure range of CO₂ at around 70°F. • Eliminate any pressures that seem far too low to rapidly discharge CO₂ or unrealistically high for standard portable extinguishers.
