What element must be checked on a fire extinguisher during inspections?

During fire extinguisher inspections, it's essential to check the pressure gauge to ensure that the extinguisher is fully charged and ready for use. The pressure gauge indicates whether the extinguisher is in the operational range; if the needle is in the green zone, the extinguisher is properly charged. If the gauge shows pressure below the recommended level, the extinguisher may not be effective in an emergency, necessitating maintenance or replacement.

While the expiration date, color, and manufacturer's label also play roles in the overall assessment of a fire extinguisher, the pressure gauge provides immediate insight into its functionality. Ensuring the extinguisher is pressurized and ready to operate is paramount for safety, particularly in critical fire-response situations.
