When should you not attempt to extinguish with a portable extinguisher?

• A. There is a small, contained flame.
• B. The fire is beyond your ability to control; exit and call for help.
• C. The area is well lit.
• D. The extinguisher gauge is in the green.

Answer: (B)

Knowing when to use a portable extinguisher comes down to your ability to control the fire and still have a safe way out. If the flame is small, contained, and you can reach a clear exit behind you, you may attempt to put it out using proper technique. But if the fire is beyond your ability to control—growing quickly, spreading to new areas, or threatening your escape route—do not try to fight it. Leave the area and call emergency services.

Keep in mind that a well-lit area or the extinguisher’s gauge being green doesn’t by itself guarantee safety. The gauge only indicates pressure, not how large or dangerous the fire is. The priority is always to get out safely and get help if there’s any doubt.
