Which type of extinguisher must not be used if it shows signs of corrosion?

• A. Only water-based extinguishers
• B. Stainless steel shell extinguishers
• C. Dry chemical extinguishers
• D. Foam extinguishers

Answer: (B)

Stainless steel shell extinguishers are designed to withstand harsh environments and resist corrosion, but even they can suffer from wear and tear over time. Corrosion can compromise the integrity of the extinguisher, potentially leading to leaks or failure to function properly in an emergency. If a stainless steel extinguisher shows signs of corrosion, it may indicate a structural issue that could impair its effectiveness and safety during use. It's essential to inspect fire extinguishers regularly, and any sign of corrosion warrants immediate attention, such as removing the extinguisher from service or having it tested by a professional. Ensuring that extinguishers are free from corrosion is crucial for maintaining their reliability and performance, as the potential consequences of a malfunctioning extinguisher during a fire can be severe. In contrast, other types of extinguishers may have different materials and coatings that might handle corrosion differently, making the stainless steel extinguisher's corrosion a particular concern.
