How often should foam concentrate and its storage containers be inspected?

The correct answer is that foam concentrate and its storage containers should be inspected at least annually. This frequency is recommended to ensure that the foam concentrate remains effective and that the storage conditions are adequate to maintain the integrity of the foam. Regular inspections help identify any signs of degradation, leaks, or other issues that may compromise the system's functionality when needed.

Annual inspections allow for a systematic check of the containers, including assessing for proper seals, contamination, and environmental factors that could impact performance. By adhering to this guideline, facilities can ensure their fire suppression systems are reliable and ready for use in emergency situations. The annual inspection schedule also aligns with industry standards and best practices for fire protection systems, promoting overall safety and compliance with regulations.
