What is one requirement for nonrechargeable extinguishers during inspection?

Nonrechargeable extinguishers, also known as disposable extinguishers, have specific requirements during inspection to ensure their reliability and effectiveness. One of the key requirements is the checking of safety seals and tamper indicators. This is crucial because these seals are designed to show if the extinguisher has been used or tampered with since its last inspection. If the seal is broken or the tamper indicator shows signs of unauthorized access, it may indicate that the extinguisher is not in proper working condition and needs to be replaced.

Regular inspection of these components helps in maintaining critical safety standards, as any compromise in the integrity of the extinguisher could lead to failure during an emergency. Ensuring that safety seals are intact contributes to overall fire safety preparedness.

In contrast, while replacing extinguishers on a yearly basis might be a good practice, it is not a standard requirement for all nonrechargeable models. Pressure indicators are generally not applicable to nonrechargeable extinguishers because they are designed to be single-use and disposed of once activated. Additionally, the seasonal timing of inspections, such as only inspecting in winter, is not aligned with safety protocols, which emphasize the need for regular inspections at set intervals throughout the year.
