During extinguisher inspection, the weight should be what?

• A. Underweight
• B. Overweight
• C. Proper weight
• D. Unknown weight

Answer: (C)

The weight should be the proper weight for that extinguisher. This confirms the unit is charged to the manufacturer's specification with the correct amount of agent and propellant, so it will operate effectively when needed. If it’s underweight, contents or pressure have likely been lost, reducing discharge performance. If it’s overweight, the extinguisher is overcharged, which can cause leakage, venting issues, or even safety problems. Unknown weight offers no assurance of readiness. During inspection, verify the actual weight against the label’s stated weight or tolerance; if it’s not within spec, arrange service rather than using it.
