🔍 Key Concepts

• Difference between cartridge-operated and stored-pressure extinguishers • What items must be checked to ensure the propellant will work when activated • Typical contents of a dry chemical extinguisher and how often they are replaced

💭 Think About

• Ask yourself: in a cartridge-operated extinguisher, where is the expellant gas stored, and what must be true about it for the unit to function? • Which of the listed actions would you expect to do every year, versus only after use or on a longer maintenance interval? • Which item, if not checked, would most directly cause the extinguisher to fail to pressurize when you squeeze the handle?

✅ Before You Answer

• Identify which option deals directly with the separate gas cartridge used to pressurize the extinguisher on activation. • Decide which options sound like they apply more to stored-pressure extinguishers with built-in gauges instead of cartridge-operated types. • Consider manufacturer and NFPA guidance: is the dry chemical usually discarded annually, or only if contaminated/caked?
