What indicates that a fire extinguisher is ready for use?

• A. The tag is expired
• B. It is in the green zone
• C. It is damaged
• D. It is not secure

Answer: (B)

A fire extinguisher is ready for use when it shows a reading in the green zone on its pressure gauge. This indicator tells you that the extinguisher has the proper pressure to function effectively in an emergency. Proper pressure is crucial for the device to discharge its contents properly. If the gauge is in the red zone, it indicates that the extinguisher is either over-pressurized or under-pressurized, both of which can prevent it from working effectively when needed.

Other conditions, such as an expired tag, damage, or being unsecured, would not assure readiness for use. An expired tag means maintenance may not have been performed as needed, damage could affect the extinguisher's functionality and security ensures that it is readily accessible in an emergency situation. These factors are important, but the critical element indicating readiness is the gauge being in the green zone.
