🔍 Key Concepts

• Basic steps to operate a portable fire extinguisher (PASS method) • How the locking/safety mechanism on most extinguishers works • What actions are not necessary for CO₂ extinguishers (shaking, turning over, side valves)

💭 Think About

• Think about what must be done before the handle can be squeezed to discharge the agent. • Consider which step is required on almost all types of portable extinguishers, not just CO₂. • Ask yourself: which option actually removes a safety device, and which options are unnecessary motions?

✅ Before You Answer

• Verify which part of the extinguisher prevents accidental discharge and how you make it ready to use (safety device). • Check standard fire extinguisher operating sequence often remembered by a 4-letter acronym. • Confirm that CO₂ extinguishers are stored pressurized and do not need to be turned upside down or shaken to work.
