How often do rechargeable fire extinguishers need to be re-inspected?

• A. Monthly
• B. Annually
• C. Every two years
• D. Weekly

Answer: (B)

Regular maintenance for rechargeable fire extinguishers includes a formal re-inspection by a qualified technician on an annual basis. While a quick monthly visual check is important to confirm accessibility, placement, and obvious damage or leakage, the professional re-inspection ensures the extinguisher’s internal mechanism, pressure, seals, tamper seal, and overall condition meet the required standards. This annual service may also note any need for recharge or parts replacement to keep the unit fully operable.

Other intervals described—weekly or monthly—are either routine checks or too frequent for formal re-inspection, and a two-year interval does not align with standard maintenance schedules. So, the best answer is that rechargeables should be re-inspected annually.
