How long before loading or discharge operations should high-level alarms be checked?

High-level alarms are critical safety devices on tankers used to prevent overflowing during loading or discharge operations. Checking these alarms in advance is essential to ensure that they are functioning correctly. Industry best practices recommend that high-level alarms be tested 24 hours prior to loading or unloading operations. This timeframe allows for any necessary repairs or adjustments to be made if the alarms are found to be malfunctioning, thus ensuring the safety of the operation and compliance with safety regulations.

Conducting a check too close to the operation, such as just 1 hour beforehand, may not provide enough time to address any issues that arise. By testing the alarms 24 hours in advance, crew members can verify their performance under simulated conditions, confirming that they will activate as needed during the actual loading or discharge process. This approach prioritizes safety and operational readiness, helping to mitigate the risks associated with cargo operations.
