Where should you keep a fire extinguisher in the lab and how often should it be inspected?

• A. On the ceiling; inspected weekly.
• B. Mounted on a wall or in an accessible cabinet; visually inspected monthly; serviced annually.
• C. In a drawer; never inspected.
• D. In a high shelf; inspected yearly.

Answer: (B)

Keeping fire extinguishers accessible and maintained is essential in any lab. The best approach places the extinguisher on a wall or in an accessible cabinet so you can grab it quickly and unobstructed in an emergency, rather than up on a ceiling, in a drawer, or on a high shelf where it’s hard to reach or easy to forget. Regular checks are about readiness. Visually inspecting each month means confirming the pressure gauge is in the correct range, the safety pin and tamper seal are intact, the nozzle and hose aren’t cracked or blocked, and the cylinder shows no corrosion or dents. The mounting hardware should be secure and the area around the extinguisher clear so you can grab it without delay. If anything looks off, it should be tagged and taken out of ordinary service until it’s repaired. Annual service by a qualified technician goes deeper. It includes a thorough internal inspection, ensuring the extinguishing agent is intact and properly charged, testing safety features, and performing required maintenance or hydrostatic tests as recommended for the extinguisher type. Documentation is updated to reflect the service. Other placements compromise immediacy and certainty of operation. A ceiling-mounted extinguisher is harder to reach and could be blocked or damaged; a drawer or a high shelf makes access slow and uncertain; relying on yearly inspection alone doesn’t provide ongoing confirmation of readiness.
