How do you tell if a lavatory extinguisher has discharged?

• A. Red Dot
• B. Black Dot
• C. White Dot
• D. No Color Change

Answer: (B)

A lavatory fire extinguisher uses a simple visual discharge indicator to show if it has been used. There’s a small indicator window on the extinguisher with a dot that changes when the agent is released. When the extinguisher is discharged, the indicator turns black, so you’ll see a black dot. If it hasn’t been discharged, there’s no black dot present (no color change or a different, unused appearance). That’s why the presence of a black dot is the best cue that the unit has already been activated and needs servicing or replacement.
