How can you verify cooling system effectiveness for reactive hazards?

• A. Only annual review.
• B. Regular maintenance, calibration, real-time temperature monitoring, and alarms.
• C. No monitoring is needed.
• D. Rely on supplier data.

Answer: (B)

To verify cooling system effectiveness for reactive hazards, you need ongoing assurance from regular maintenance, calibration of sensors and controllers, real-time temperature monitoring, and alarms. This combination creates continuous visibility into how the cooling system is performing and provides early warning if temperatures begin to rise.

Regular maintenance keeps pumps, valves, fans, cooling jackets, and related equipment in good working order, reducing the chance of failures that could lead to overheating. Calibration ensures temperature sensors and controllers provide accurate readings, so responses are based on true conditions rather than drift. Real-time monitoring allows you to track temperature trends and spot deviations as they happen, enabling prompt intervention before escalation. Alarms trigger immediate notifications and, if configured, automatic responses to reduce heat generation or activate cooling, preventing runaway scenarios.

Relying on an annual review misses in-between changes and wear; having no monitoring leaves you blind to temperature excursions; relying only on supplier data may not reflect on-site conditions or equipment health.
