Question 1 of 27070

To operate a portable foam fire extinguisher, you should __________.

🔍 Key Concepts

• Types of portable extinguishers (foam vs. CO₂ vs. dry chemical) • How foam extinguishers are charged and discharged • Standard operation steps: safety device, activation method, and application technique

💭 Think About

• Think about what has to happen inside a foam extinguisher to mix and expel the foam—how is it started? • Ask yourself which option describes a general fire extinguisher safety step, and which describe actions specific to certain older types of extinguishers. • Consider which action could actually damage the extinguisher or prevent it from working correctly.

✅ Before You Answer

• Verify which answer matches how a portable foam unit (not CO₂ and not cartridge-operated dry chem) is normally activated. • Eliminate any choice that would clearly be unsafe or likely to disable the extinguisher. • Check whether the step involves first removing any safety device that prevents accidental discharge, then using the normal trigger/control.
