Commercial Refrigeration & Health and Safety

If your refrigeration system can’t hold temperature or recover quickly after door openings, it puts your business at risk both legally and financially.

Key checks to stay compliant:

1. Consistent temperature ranges for each product category
2. Digital or manual temperature logging
3. Working alarms and monitoring for faults
4. Fast cooling recovery after restocking
5. No expired refrigerants or faulty seals
